Leírás:
Nagyon halvány, éléről látszó galaxis, K-Ny elnyúltsággal. Felülete sima, semmilyen központi fényesedés nem látszik, de a mag mandula formájú, és ennek déli oldala némileg laposabbnak tűnik, mint az északi. Alacsony nagyítással vizsgálva egy látómezőben szerepel a közeli NGC 3021 galaxissal.

A very faint edge-on galaxy with an E-W elongation. Its surface is very smooth without any sign of a brighter central region, but its central bulge is almond shaped with its Southern side somewhat flatter than its Northern. When viewing with low magnification, it appears in one FoV with the nearby galaxy NGC 3021.

Leírás:
Közeli társánál, az NGC 3003 galaxisnál fényesebb, de nagyon kis méretű galaxis. Majdnem tökéletesen kerek alakja van, kivéve, hogy - főképp elfordított látással vizsgálva - a nyugati oldala nagyobbnak tűnik, ettől a galaxis alakja esőcsepp-formát vesz fel. Ezen részletet leszámítva nem mutat más érdekességet, habár magát a látómezőt elég látványossá teszi egy előtércsillag, nagyon közel a galaxishoz, attól DK-re.

Description:
Brighter than its nearby companion, the NGC 3003 galaxy, but it is very tiny. It has an almost perfectly circular shape, except that especially with averted vision its Western side seem to grow, making the galaxy look like a raindrop. Beside this feature it shows no details, although the FoV itself is interesting with the foreground star to the SE very close to the galaxy.

Description:
The famous double galaxy of Ursa Maior is an easy target with any kind of telescope. The brighter M81 spiralgalaxy can be detected even in the finderscope. Its smaller and fainter companion, the irregular M82 is interesting especially when looking at larger magnification levels, with several clearly detectable dense areas. Looks best when having a FoV of at least 1°, as in that case both of the galaxies can be fit into one picture. The nearby NGC 3077 is also worth a look, although it's even smaller and fainter than the M82.

Description:
NGC 3184 is much brighter, a perfectly round, face-on galaxy, while its companion is a much fainter nearly edge-on galaxy dancing on the border of direct visibility. The 3184 has a brighter core that isn't round but rather amorphous, and features a brighter arc on the SW side of the galaxy. Later by checking photos I've found that these are all spiral features, it's a really exciting object. NGC 3179 has an almost star-like core, with a real star nearby.

Description:
Extremely faint - at least to my little Newtonian. Elongated by 1:4 in the E-W directions. It has a somewhat heavy position, and to tell the truth, I've found the galaxy after a longer search. I can detect the GX only with averted vision most of the time. Its core is only a little bit brighter than its surface, and has a shape of an almond. Sometimes its Southern half appears brighter than the Northern.

Description:
An interesting and very spectacular trio of galaxies in the constellation Leo. NGC 3222: the westernmost member is a really faint slightly elongated galaxy of about 13 magnitudes only. Its core is like a star, with quickly increasing luminosity. To the SW of this I can detect a faint little star in front of the galaxy. NGC 3226 and 3227: spectacular, closely interacting couple, no wonder it was included in Halton Arp's famous catalogue of peculiar galaxies with the number 94. Among them the latter is much brighter and larger with a star-like core which brightens quickly. The 3226 is the opposite of this with a really homogeneous surface and almost no visible core.

Északra és délre ettő két körívet látok, melyek a galaxis felületénél némileg fényesebbek bár nem vagyok benne biztos, hogy nem csak egy optikai illúzió áldozata lettem. A későbbi ellenőrzés alapján vizuálisan csak a galaxis központját láthattam.

Description:
Tiny, faint galaxy with a strong elongation to the SW-NE direction. Its core is definitely brighter but instead of featuring a star-like core, it displays a little central disk. To the North and South of this I can see two arcs that are somewhat brighter than the surface of the galaxy, although I'm not sure if what I see is only an illusion. According to a check I've done later, I've only witnessed the central part of this object.

Description:
Faint but star-like core with a magnitude of about 13.5. The galaxy itself is faint, does not show any structures. This may be because of the terrible atmospheric conditions, as on astrophotographs it shows arms that seem quite an easy catch. These arms can only be suspected because of the slightly elongated ellipse shape, as the galaxy is in fact almost perfectly face-on - this means that the ellipse shape is formed because of the two arms in the N-S directions. An interesting feature is a bright foreground star.

Description:
The M97, also known as the Owl-nebula is a very spectacular, famous planetary, in the vicinity of M108. It's a nearly regular circle, slightly elongated in E-W directions. Also on the Eastern and Western corner one can find two darker spots, the eyes of the owl. The planetary itself is quite an easy object, looks much brighter than the 11m as listed in catalogues, a homogenous shape with sharply fading edges. Discovering the eyes is a bit harder: especially the Western spot is tend to blink. Using your averted vision helps a lot to see the details. I was using my Baader UHC filter to finish this sketch, however according to my experiences a slightly better seeing helps much more than the filter.

Description:
This triplet of galaxies always make me smile: I'm calling it a "dumb face" cluster. The M65-66 double is a classic, easy Messier-object: both can be well seen - perhaps the latter having a brighter, almost star-like core region. It's not clear for me why the NGC 3628 was left out of Messier's catalogue: it's not at all a difficult object either. Its brightness is quite close to that of M65 and while wandering around looking for its more famous companions, you may most probably bump into this one also.

Description:
A very spectacular interacting couple in an environment sparsely populated by field stars. NGC 3718 is much larger, a perfectly face-on spiral galaxy, that is also catalogued by Arp with number 214. It feels as if it has a much larger area than what can be detected by direct vision. To the East of the galactic core I notice a brighter arc, however apart from this little detail and the little bit brighter core it has a really homogeneous look. The smaller NGC 3729 shows the typical core area of an edge-on galaxy, however according to astrophotos, what I see is a bit tricky, and the galaxy itself is far from being edge-on.

Description:
Two bright but small galaxies are visible in the exepiece. Although the catalogues say that the face-on NGC 3738 is is almost 1 magnitude brighter than the nearly edge-on NGC 3756, visually the later one is clearly a lot brighter. The NGC 3738 is barely brightening near its core, and shows no star-like nucleus. The oval shaped NGC 3756 is almost perfectly even in brightness, displays no brighter parts. I notice that it's a bit asymmetric, the Western side of the ellipse is a bit flatter. SQM reading: 21.19,/arcsec2, 0°C (guess we're having a negative temperature record, where's the global warming?).

Description:
Large, spectacular galaxy. Perfectly round, shows no sign of a star-like core, although its central region is a bit brighter. It's very faint, but I can observe some brighter details around the core. By checking out photographs today, it's now obvious that these spots are parts of a spiral structure. SQM reading: 21.20m/arcsec2, 5°C, very humid.

Leírás:
Apró, halvány, ovális galaxis, É-D nyújtottsággal, bár valódi alakja leginkább csak elfordított látással mutatkozik meg. Magja igazán látványos apró, fényes kerek alakjával. Az objektumtól északra és délre rengeteg fényes csillag láthtó, de érdekes módon a használt nagyítás mellett a látómező viszont teljesen kihalt.

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.

Description:
A very faint galaxy, I see no star-like nucleus, however the central regions are somewhat brighter, and show many barely discernible brighter knots on the long axis of the galaxy. High humidity kills details.
This is my first real observation in self-made observatory (besides a quick check of Jupiter without proper collimation after I've transferred my light-bucket to the dome). Climate is excellent, plenty of space, the radio is on, very cozy place. What I've quickly discovered is that I must pay attention not to reach the side of the slit with the OTA's light path plus I've found that the SQM sees quite a lot in infrared despite the block filter in front of its detector. I have a strong infrared floodlight to support my security cameras that are watching the dome, and if I leave the infrared lights on, the SQM measures about 16 MPSAS instead of 21. Sorry for this interruption, now back to the observations. ;)

Description:
WNW-ESE elongated, almond shaped galaxy. Visible directly at an instant. Small, no stellar core visible. Its Northern half appears slightly brighter. I've observed this galaxy as a mistake, because I've already bagged it almost exactly one year ago: here. Seems that my logs are not really accurate and some of my observations may be missing from the "already observed" list of mine. :)
