King 6 (Open cluster)
Right ascension: 3h 28m Declination: 56° 27'
Constellation: Camelopardalis
Date/time: 2008.03.15 19:00 UT
Equipment: 12" f/5 Newtonian
FoV: 27' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Even the brightest star of this 6-7' cluster is only 10m, and all the rest of its brighter stars (about half a dozen) are also near 12m. Hidden in the background are even fainter members (about 30-35), which can be seen by averted vision to the 14th magnitude or so. It has a fuzzy background, suggesting plenty of even fainter stars.

M52 + OCL261 (Open cluster)
Also known as: NGC 7654 + Czernik 43 (Cz 43)
Right ascension: 23h 24m Declination: 61° 35'
Constellation: Cassiopeia
Date/time: 2008.01.24 18:00 UT
Equipment: 12" f/5 Newtonian
FoV: 40' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

These two star clusters can be found easily nearby the constellation Cassiopeia. The Messier object M52 is a quite large open cluster with clearly identifiable boundaries and has a diameter of at least 20'. Its image is determined by a very bright star, however the cluster itself looks quite rich, even though the brightness of other stars is not even close to their brightest companion. To the east from M52, behind a wall of shiny stars lies the open cluster OCL261 (also known as Czernik 43), populated with a dozen dim stars.

Stock 10 (Open cluster)
Right ascension: 5h 39m Declination: 37° 56'
Constellation: Auriga
Date/time: 2008.02.12 18:00 UT
Equipment: 12" f/5 Newtonian
FoV: 52' Magnification and filter(s): 45x
Seeing: 7/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

If I wouldn't check this object out previously with my planetarium-software, I would most probably didn't even notice this sparsely populated open cluster through the telescope. Catalogues claim that it has a diameter of around 25', however it looks larger to me. Its three brightest 7m members rule the field of vision. Unfortunately at the time of this sketch, the Moon was in a phase of around 35%, painting the entire sky gray, which is probably the reason why I haven't noticed any stars brighter than 13m in the area even by using averted vision, no matter that there were an excellent seeing this time.

Stock 23 (Open cluster)
Right ascension: 3h 12m Declination: 60° 0'
Constellation: Camelopardalis
Date/time: 2008.02.20 19:00 UT
Equipment: 12" f/5 Newtonian
FoV: 20' Magnification and filter(s): 71x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This is a large open cluster with a diametre of around 15'. Not that spectacular, although it can be clearly distinguished from its environs that is relatively poor in stars. It has two separate shiny parts, with the brightest stars as shiny as 7.5-9 magnitudes, sparkling in all different colours. The Western part of the cluster has an optical double at its end towards the middle of the cluster that can be easily separated, and where both members are also real doubles in themselves. However, I could not resolve those doubles at this magnification level.

Trumpler 1 (Open cluster)
Also known as: Tr 1
Right ascension: 1h 36m Declination: 61° 17'
Constellation: Cassiopeia
Date/time: 2008.02.19 19:00 UT
Equipment: 12" f/5 Newtonian
FoV: 18' Magnification and filter(s): 167x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

In the neighborhood of the M103 located this tiny but spectacular open cluster. 71x: the object probably looks the nicest on this magnification. It's notable figure is a little line formed by four stars of around the same (11-12) magnitude. 167x: the cluster itself is less spectacular on this power, however one of the four stars splits to a binary of two dim (13m) stars. The OC has an easy position, and is a very interesting, spectacular view, worth taking a look at it.

Trumpler 2 (Open cluster)
Right ascension: 2h 37m Declination: 55° 59'
Constellation: Perseus
Date/time: 2008.01.26 18:00 UT
Equipment: 12" f/5 Newtonian
FoV: 30' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Nice open cluster in the neighborhood of the famous double-cluster of the constellation Cassiopeia. It has a quite large diametre of 20'. Its most notable member is the 7.38 magnitude red giant star, HD 16068.

Trumpler 3 + PNG138.1+04.1 (Open cluster)
Also known as: Tr 3
Right ascension: 3h 12m Declination: 63° 15'
Constellation: Cassiopeia
Date/time: 2008.01.26 20:00 UT
Equipment: 12" f/5 Newtonian
FoV: 45' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This open cluster is located in a star field that's free from bright stars. Its most remarkable figure reminds me of a reaping-hook, and is composed by four stars between magnitudes 9 and 10. These are also considered the brightest members of the cluster, besides these only a couple of stars of 8-10m are visible in the field of vision, but most of the members are fainter than 12m. For about 20' to the south is the planetary nebula PNG138.0+04.1, but its nebulosity can only be suspected even by using averted vision - the large, 5.5' diameter planetary cannot really be seen even with the UHC filter on. However, its 13m central star can be found and a little haziness can be detected next to this star that is probably illuminated by the brighter stars next to the central one.

NGC 1545 (Open cluster)
Also known as: Collinder 49 (Cr 49)
Right ascension: 4h 21m Declination: 50° 15'
Constellation: Perseus
Date/time: 2008.02.11 19:00 UT
Equipment: 12" f/5 Newtonian
FoV: 40' Magnification and filter(s): 71x
Seeing: 3/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This cluster is not too dense and not at all spectacular, for me its only charm was the northern star of the triangle made up of three bright stars with its nice red/orange colour. Its environs are moderately rich in stars, its boundaries are hardly noticeable, because it perfectly fades into its surroundings.

NGC 2281 (Open cluster)
Also known as: Cr 116
Right ascension: 6h 48m Declination: 41° 5'
Constellation: Auriga
Date/time: 2008.01.24 19:30 UT
Equipment: 12" f/5 Newtonian
FoV: 15' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This open cluster can be located easily, yet it doesn't cover a large area. It has half-dozen brighter and at least 20 fainter members. Its most notable pattern is the diamond made up by four bright stars in the middle of the cluster. The OC is clearly separated from its environs.

The Coathanger (Asterism)
Also known as: Collinder 399 (CR 399), Brocchi's cluster
Right ascension: 19h 27m Declination: 20° 09'
Constellation: Vulpecula
Date/time: 2009.06.19 21:00 UT
Equipment: 10x50 binoculars
FoV: 3° 30' Magnification and filter(s): 10x
Seeing: 4/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This famous cluster demands a huge FoV, that can only be achieved by binoculars. At a NELM of about 5 magnitudes, you may notice it with your bare eyes as a large, diffuse spot. The coathanger shape is formed by 10 shiny stars, and the background is painted grainy by the Milky Way.

FoV: 21' Magnification and filter(s): 167x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

The component A is estimated at 4.6m with white colour, component B at 5.5m and looks like it has a touch of blue in it. At 71x they are only separated if the seeing permits. At 167x they are perfectly separated, B looks definitely fainter. Separation is estimated at 4.1" with a position angle (PA) of 315°.

Lovro 2 (Asterism)
Right ascension: 0h 22m Declination: 24° 50'
Constellation: Hercules
Date/time: 2009.09.16 00:00 UT
Equipment: 12" f/5 Newtonian
FoV: 1° Magnification and filter(s): 71x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

A fairly large asterism made up of stars of similar brightness and colour. It clearly separates from its environs, however it is only an asterism and not an open cluster according to the data I could put my hands on. It resembles either a double questionmark, or the flames of a large torch. Sofar I couldn't find any catalogue that listed this object as an asterism, so I decided to use the designation of Lovro 2. However, please not that this is a totally unofficial designation.

Appeared in Sky & Telescope 2013/01.

3C 147 (Quasar)
Also known as: PGC 2355407
Right ascension: 5h 43m Declination: 49° 40'
Constellation: Auriga
Date/time: 2010.02.15 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: 34' Magnification and filter(s): 100x
Seeing: 7/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This is actually an unsuccessful observation, I still believe it should be posted here because it shows how hard is the life of an ordinary visual observer. :) The map I'm using (Triatlas B) shows stars and DSO's to approximately 12 mags. I found this quasar in Auriga and I was sure I'll be able to take a glimpse of this distant object. Without exact position data, I decided to sketch the field of stars and identify the actual quasar later. Unfortunately my astronomy program did not show any quasar here to the 16.5 magnitudes. The reason is that it lists the quasar at 18.2. I've googled the Vmag of this QSO, and found brightness data anywhere from 15.0 to 17.8m. At 15 magnitudes I should be able to see the object surely with averted vision (we had 100% snow coverage, so the NELM was not as good as it used to be). So, what I've learned from this is that brightness information must be handled with special care, especially for faint and exotic objects.

C/2009 K5 (McNaught) (Comet)
Also known as: Comet McNaught K5
Right ascension: 22h 40m Declination: 79° 31'
Constellation: Cepheus
Date/time: 2010.05.10 22:00 UT
Equipment: 12" f/5 Newtonian
FoV: 13' Magnification and filter(s): 100 x
Seeing: 6/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Even the finderscope displays this comet like a very faint spot. At 100x it shows a very nice occultation with two brighter stars. Very nice gradient change in its brightness, slightly oval shape, bright but tiny core. A very small diametre of about 1.2'.

C/2009 K5 (McNaught) (Comet)
Right ascension: 23h 21m Declination: 81° 10'
Constellation: Cepheus
Date/time: 2010.05.12 23:30 UT
Equipment: 12" f/5 Newtonian
FoV: 25' Magnification and filter(s): 100x
Seeing: 6/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

The comet is easy to find in the finderscope as a very faint spot. Nice gradient change in its brightness, definitely oval shape, bright and tiny core. The diametre looks much larger than two days ago, perhaps this is because of the better atmospheric conditions. I estimate a size of about 2.5' x 1.9'.

Hickson 68 (Galaxy)
Also known as: NGC 5350 + NGC 5353 + NGC 5354 + NGC 5355
Right ascension: 13h 54m Declination: 40° 17'
Constellation: Canes Venatici
Date/time: 2010.05.12 22:45 UT
Equipment: 12" f/5 Newtonian
FoV: 20' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Fantastic spectacular group of galaxies. I can catch 4 of 5 group members. NGC 5353 and 5354 are showing star-like core, NGC 5350 does not show such a feature, although this is clearly the largest of all. NGC 5355 is the faintest, it's so dim that it's hard to detect its exact shape and position angle (PA). Hickson designations are: 68a = NGC 5353 (11m), 68b = NGC 5354 (11.4m), 68c = NGC 5350 (11.3m), 68d = NGC 5355 (13.1m), 68e = NGC 5358 (13.6m). Unfortunately I was unable to detect the last one of the quintet, but it should be visible on a better night.

NGC 2655 + SN2011B (Galaxy)
Right ascension: 8h 57m Declination: 78° 11'
Constellation: Camelopardalis
Date/time: 2011.01.28 17:30 UT
Equipment: 12" f/5 Newtonian
FoV: 25' Magnification and filter(s): 167x
Seeing: 7/10 Transparency: 2/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Unfortunately the galaxy is located on a light polluted portion of the sky, yet it is easily visible with 71x including the suprisingly bright supernova SN2011B to the ESE. I estimate that the brightess of the supernova is around 12.8m, about the same as the star-like core of the galaxy itself. Because of the light pollution, sometimes it looks as if the SN is just outside the galactic plane: this is because I probably see only the internal regions of the GX. SQM reading: 20.53m/arcsec2, high humidity, -7°C.

NGC 3972 + NGC 3982 + NGC 3990 + NGC 3998 + SN 2011by (Galaxy)
Right ascension: 11h 58m Declination: 55° 16'
Constellation: Ursa Major
Date/time: 2011.05.06 20:30 UT
Equipment: 12" f/5 Newtonian
FoV: 32' Magnification and filter(s): 100x
Seeing: 4/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

My original plan was to observe the supernova SN 2011by, the newest celebrity in the stellar world. However, as it is located in an area full of spectacular galaxies, I decided to sketch the galactic neighborhood too. The supernova itself is very bright, even brighter than what I expected, and compared to the nearby stars, I estimate a brightness of abour 13.2m! It is by far brighter than the surface of the parent galaxy, NGC 3972. The two large face-on galaxies (3998 and 3982) are the brightest in the FoV, the tiny 3990 is only slightly fainter than these, The 3972 is however very faint, and I cannot detect the nearby 3977 at all. Perhaps I should try again on a night with better seeing. SQM: 21.12m/arcsec2, 2°C.

M51 + SN 2011dh (Galaxy)
Also known as: Whirlpool galaxy
Right ascension: 13h 30m Declination: 47° 8'
Constellation: Ursa Major
Date/time: 2011.06.21 21:30 UT
Equipment: 12" f/5 Newtonian
FoV: 25' Magnification and filter(s): 167x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Today was the Summer solstice, so it's not surprising that even at 11pm the Western horizon is still shining in bluish colour, however at East the hazy patch of the Summer Milkyway is already easily noticeable. The spiral structure of the M51 is readily visible at 71x, surprisingly easy and so is the supernova SN2011dh, which I estimate to be at 12.3m and is located in the middle of a large outer spiral arm towards ESE from the galactic core. At such a high brightness this supernova is possibly one of the brightest for this year, at a very easy position for Northern hemisphere observers also with much smaller scopes.

Crater Gutenberg (Our Moon)
Also known as: Crater Gutenberg, Rimae Goclenius
Right ascension: h m Declination: ° '
Constellation:
Date/time: 2011.08.17 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: ' Magnification and filter(s): 167x
Seeing: 6/10 Transparency: 2/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This crater catched my attention because of its weird potato shape. Being near the terminator, half the crater is in a shadow, but it shows plenty of little details especially at 375x : small domes and mountains scattered inside. Below the crater you can see two rimae originated from the nearby crater Goclenius. A spectacular view!

STF 2723 (Binary star)
Also known as: Struve 2723
Right ascension: 20h 45m Declination: 12° 22'
Constellation: Delphinus
Date/time: 2011.08.26 21:00 UT

Seeing: 3/10 Transparency: 4/5
SQM: 21.20 m/as2 Temperature: 22°C
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Slightly different close pair. I estimate component A (to the NW) to be 7m bright with B being about 8.5 magnitudes. Both components are white, A with a touch of blue. The estimated separation is 1.2", position angle (PA) being 125°.

Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Splits very nicely, although at 71 it displays no signs of being a binary, but at 250x it splits with a thin slit, however the component B is sometimes still covered by the diffraction spike of component A (to the SE). At 375x this very close binary splits nicely. It shows large difference in brightness. Both is white with A a bit yellowish while B very lightly bluish. I estimate A being 6.5m bright and B 10m. Note that catalogues list B as 7.7m, but I belive visually it's MUCH fainter than that! The estimated separation is 2" with a PA of 295°.

Difficulty: 2 - easily visible, some dark adaptation needed, averted vision might add to details
Position: 3 - moderate, some starhopping needed
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

When I first glimpsed this star, my jaws simply dropped and I regret, but the first thing I said was "oh f*ck". This is most probably the reddest star you can ever find. Everything I ever saw is surpassed by the looks of this star, although WZ CAS still rules the world of colourful stars with its nicely contrasting blue companion star. This variable star is a lonely one, and with its beautiful colour it's also an easy find, although it is a bit faint and you must prepare yourself for finding something in the FoV that is not a shade of white: interesting, but this uniqueness makes it a bit hard to find for the inexperienced eye!

This star is a MUST see object!

Observer: Ferenc Lovró
Description:

A very nice, colour contrasted binary. Not really tight. The primary member (A) is intense golden yellow while the secondary member (B) is blue with a tint of purple. In fact, this is not simply a binary of two stars, but I found out later while doing a research on this object that many of the other stars on this sketch are connected to the primary (as described in this document).

Location: Lipótfa, Zselic, Hungary
Observer: Ferenc Lovró
Description:

Spectacular yellow binary star, makes a nice couple especially at low magnification. The fainter companion is a little bit bluish. The primary aim for this sketch is to observe this star once every year from now on on the approximately same day in order to display how this star drifts through space compared to the other field stars - this is one of the fastest apparently moving star with about 5" per year.

Difficulty: 1 - instantly visible, no dark adaptation or averted vision needed
Position: 3 - moderate, some starhopping needed
Location: Lipótfa, Zselic, Hungary
Observer: Ferenc Lovró
Description:

One of my favorite variable/binary stars. I've found it years ago just by wandering on the sky with my telescope, and it was very easy to notice it because of the beautiful red colour of the primary star. The companion has a bright blue colour, contrasting very nicely with the primary. Their luminosity is nearly similar, they resemble me of a miniature Albireo. In fact the diameter of the FoV was about 1.5 times as large as displayed, but the sky was so dark that it was hard to see the border of the FoV in the eyepiece.

Sight: 3 - definite details, interesting look
Difficulty: 1 - instantly visible, no dark adaptation or averted vision needed
Position: 1 - very easy, many bright stars nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Beautiful golden star also known as Herschel's Garnet Star. With its high luminosity it dominates the field. As it is easily visible also with the bare eyes, it's a very easy target. If T Lyrae is unbeatable in redness, this star is probably the winner in the golden category. This star is actually one of the brightest known stars, a supermassive giant nearing the end of its life. How sad.

Sight: 3 - definite details, interesting look
Difficulty: 1 - instantly visible, no dark adaptation or averted vision needed
Position: 1 - very easy, many bright stars nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

A nice binary star, not that close to eachother, but with large difference in brightness. The colour is best noticeable with fresh, non dark adapted eyes. The primary member has a golden colour with a touch of green while the companion is deep blue with a very little purplish tint. The strong moonlight combined with moderate humidity is not a favorable condition for observation, perhaps that's why the field is lacking faint stars.

Difficulty: 4 - hardly visible, dark adaptation and very dark skies needed, averted vision is required to see details
Position: 2 - easy, bright star nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Surprisingly bright comet, its cone shape can be noticed even with the smallest magnification. Its a rather large object, by increasing power and especially by using averted vision its N-S elongated tail becomes more and more spectacular, can be separated to three definite parts: on its Western border a longer tail can be seen, in the middle a little but bright cone can be noticed and finally to the South I can see another brighter filament that's not as spectacular like the two others. Unfortunately it's not easy to observe this bright object this time, because thin clouds are going by, sometimes completely covering Alpha and Beta Herculis.

Position: 2 - easy, bright star nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

A rarely observed protoplanetary nebula I've first read about in Cloudy Night's Sketching forum. It's as small as expected, but much fainter. Elongated to the N-S, with a clearly visible dark band divinding the nebula to to halves, when the seeing gets better for a few moments. Reminds me of a faint little nearly edge-on galaxy. I haven't checked photos of this object before my observation, so I'm quite surprised now that I've seen the dark band, because even on a sketch made with 600mm scope it does not show up. But I know that my eye did not lie. A highly recommended gem.

Description:

A close colour contrasting binary. The B component wasn't easy to see as the bad seeing made the bright A component dancing in the FoV, hiding the close companion star. The main component is bright golden coloured, while its companion is much fainter white with bluish hue. Nice but difficult binary.

OK, I agree that its colour is unimaginable based on this definition, so I guess you will have to see it yourself. Quite difficult object thanks to its field and faintness.

NGC 7250 + SN 2013dy (Galaxy)
Right ascension: 22h 19m Declination: 40° 38'
Constellation: Lacerta
Date/time: 2013.07.21 01:00 UT
Equipment: 12" f/5 Newtonian
FoV: ' Magnification and filter(s): 300x
Seeing: 7/10 Transparency: 2/5
SQM: 20.01 m/as2 Temperature: 11°C
Humidity: dry Wind: none
Sight: 1 - nothing spectacular
Difficulty: 5 - almost invisible, total dark adaptation, very dark skies and averted vision is a must to see the object
Position: 4 - hard, complex starhopping needed
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

The host galaxy of the supernova SN 2013dy, NGC 7250 appears as a very faint patch of light in the FoV. I try to compensate for the bright sky background by increasing the magnification, caused by the rising full Moon and the dust in the air caused by harvesters. Yesterday my observation was negative, but today I succeeded, although it was still a very difficult task. I estimate the brightness of the supernova to nearly 12.3m visually.

Description:

Comet C/2014 Q2 (Lovejoy) is at its brightest, therefore it's easily visible with your unaided eyes in the constellation Taurus the Bull. With bare eyes it resembles M44 only brighter. With my telescope it reveals many details in its curvy tail which I can follow for about 2 degrees. The head or coma of the comet is oval, or a little bit egg shaped. The core is bright, looks like an out-of-focus star. Just beautiful! The sketch is a mosaic of about two fields.

KIC 8462852 (Variable star)
Right ascension: 20h 6m Declination: 44° 27'
Constellation: Cygnus
Date/time: 2015.11.01 17:45 UT
Equipment: 12" f/5 Newtonian
FoV: 12' Magnification and filter(s): 250x
Seeing: 7/10 Transparency: 4/5

Description:

This average-looking star hides some secret: it has a rather unusual light curve that riddles astronomers. Most probably a large swarm of comets occults the star here and then, but some believe this star may be the home of the first evidence of extraterrestrial activities: a Dyson-sphere under construction.

Humason 1-1 (Planetary nebula)
Also known as: Hu 1-1
Right ascension: 29h 09m Declination: 56° 03'
Constellation: Cassiopeia
Date/time: 2015.12.01 19:45 UT
Equipment: 12" f/5 Newtonian
FoV: 10' Magnification and filter(s): 375x
Seeing: 7/10 Transparency: 4/5
SQM: 21.12 m/as2 Temperature: 6°C
Humidity: low Wind: breeze
Sight: 1 - nothing spectacular
Difficulty: 5 - almost invisible, total dark adaptation, very dark skies and averted vision is a must to see the object
Position: 3 - moderate, some starhopping needed
Location: Talpa Minor Observatory
Observer: Ferenc Lovró
Description:

Bright but very tiny, therefore really difficult object: even at 250x it looks completely stellar. I looked for about 45 minutes at a wrong place nearby thanks to some really inaccurate sketches I used to find this planetary nebula. Turns out, some fellow sketchers did not really see this object, yet confidently drawn a similar fuzzy in a field that is nearby, even resembles the real field a bit, but they were wrong. So I've just learned that it's not only astrophotographs a visual observer shouldn't trust, but one must be precautious with sketches too. Higher magnification may be better, but I couldn't go any higher because of my rather poor condition Dobsonian mount. I've tried O-III, UHC-S and UHC filters, but neither enhanced the view worth mentioning.

PK 80-6.1 (Planetary nebula)
Also known as: Egg nebula
Right ascension: 21h 02m Declination: 36° 42'
Constellation: Cygnus
Date/time: 2017.08.14 21:30 UT
Equipment: 12" f/5 Newtonian
FoV: 11' Magnification and filter(s): 375x
Seeing: 7/10 Transparency: 4/5
SQM: 21.34 m/as2 Temperature: 15°C
Humidity: dry Wind: none
Sight: 3 - definite details, interesting look
Difficulty: 3 - moderately visible, dark adaptation needed, averted vision might add to details
Position: 4 - hard, complex starhopping needed
Location: Talpa Minor Observatory
Observer: Ferenc Lovró
Description:

At 71x it looks like a slightly de-focused star which is moderately faint and seem a bit elongated. At 250x the elongation becomes obvious in the N-S direction, and the protoplanetary nebula splits into two lobes. At 375x it looks somewhat large. The Northern part is clearly brighter and has a denser inner region. The Eastern part is smooth and resembles an arrowhead. The whole nebula appears to have a very faint halo around it. Its light is polarized: by using a polarization filter I sense a change in brightness by about 1-2 magnitudes when I rotate the filter to the correct position.

M1-92 (Planetary nebula)
Also known as: Minkowski 92, Footprint nebula, Minkowski's footprint
Right ascension: 19h 36m Declination: 29° 32'
Constellation: Cygnus
Date/time: 2017.08.14 22:10 UT
Equipment: 12" f/5 Newtonian
FoV: 6' Magnification and filter(s): 652x
Seeing: 9/10 Transparency: 4/5
SQM: 21.05 m/as2 Temperature: 15°C
Humidity: dry Wind: none
Sight: 3 - definite details, interesting look
Difficulty: 4 - hardly visible, dark adaptation and very dark skies needed, averted vision is required to see details
Position: 3 - moderate, some starhopping needed
Location: Talpa Minor Observatory
Observer: Ferenc Lovró
Description:

This protoplanetary nebula is much fainter than what I expected, but it has an easy location so it's very easy to recognize. At 71x it is completely stellar. At 250x you can suspect that it is an extended object. However, to be able to fully understand the nature of this object, you need to go into extreme magnification levels. Fortunately I had an excellent seeing this evening, so I was able to use my 2.3mm eyepiece (for the first time in the past decade) and view the object at 652x. It has a strong NW-SE elongation, and the shape of an eye. Its NW side is brighter and it has the shape of a drop. The SE side consists of a faint arc and an area that is even fainter and completes the eye shape. Between the two sides of the protoplanetary nebula a thin slit can be seen. The most interesting feature of this object is that it definitely looks blue!
