Description:
A small, triangle shaped open cluster sitting in a sparse stellar environment. A very bright star dominates the cluster at one of its corners, but I suspect that this star is not actually a part of this group. Apart this, the cluster shows about a dozen of brighter and another dozen of fainter members.

Description:
A very nice, large open cluster, covers half the FoV, nicely separates from its stellar neighborhood. I count 8 brighter and dozens of fainter stars in the cluster. There are two especially nice features: one of them is the stellar arc between two brighter stars in the middle of the sketch, and the other one is the nice trapezoid of stars right above this arc. Full moon is getting closer and closer to the cloud-covered horizon preventing me from further observation.

Description:
A rather small cluster, but still with many bright members in the constellation Orion. You can find it easily, tho a medium magnification will be neccessary to reveal fully its figure, that is made up of two separate parts. At the end of one of these patterns sitting a very close binary star, both stars with high magnitudes yet can be separated easily, even with a power of around 100x. This cluster is ofter referred as "The 37 cluster", as its stars form a large cosmic 37. :)

Description:
You can find this sparsely populated, large open cluster near the star ß Mon in Monoceros. In its center shines the star HR 2344 (HD 45546), which is a mag 5 star - therefore it is visible with the naked eye even from moderately dark places. The cluster has many members brighter than 10m, so it looks nice even through an ordinary finderscope, and because of its size and sparse density you shouldn't go for powers higher than 50-75x when looking at it.

Leírás:
Ez az aránylag ritkán említett Messier-objektum már a keresőtávcsőben is nagy, diffúz foltként látszik. Alacsony/közepes nagyítással egy sűrű, tömör nyílthalmaz tárul szemünk elé. A halmaz egy különösen szép tagja a középponttól körülbelül 9'-re északra látható vörös óriás 1.7-es szín indexszel, HD 52938 névvel katalogizálva. 7.82 magnitúdós fényességével ez egyben a halmaz legfényesebb tagja. Fényes vörös színe miatt érdekes módon nem gondolnám, hogy 2 magnitúdóval fényesebb a többi csillagnál a halmaz központjában, inkább utóbbiak látszódnak fényesebbnek.

Description:
This rarely mentioned Messier object looks like a diffuse, large spot even through the finderscope. On a low/moderate magnification a view of solid, dense open cluster appears in front of our eyes. A very nice member of the cluster can be found around 9' north from the middle of the cluster: a red giant of a color-index of 1.7, catalogued as HD 52938. With its 7.82 magnitude luminosity its also the brightest star of the cluster. Interestingly, because of its shiny red colour, I wouldn't think that this star is nearly 2 magnitudes brighter than the other stars in the centre of the cluster, which look like they're the brightest by far.

Description:
A tiny, faint planetary nebula in the constellation Gemini, a relatively easy find. Its double lobed shape can be recognized even with very small magnifications (at 71x its shape was very obvious), but shows much more details with high powers. In the two parts two star-like false cores can be seen. Its Northern half looks a bit triangular, while its Southern half appears to grow significantly to SE when using averted vision. UHC filter helps a little but is not necessary and ruins the looks of the stellar neighborhood while an O-III makes it even fainter so is not recommended.

Description:
Also known as the Eskimo or Clown face nebula, this planetary is the real gem of the constellation Gemini. It's a very bright object, showing much details and is quite unresponsive on filters. I estimate the brightness of its tiny, star-like core about 11 magnitudes, with two perfectly regular concentric circles around it, each with surface brightnesses about 1 magnitudes fainter than this. The diametre of the inner circle seems exactly the half of the entire object.

Description:
I've sketched this planetary about a year ago, but obviously I did not mark it as "SKETCHED" in my list of objects, so the result is a new drawing. However, when I compared the two sketches, it was obvious to make this mistake, because now - even if conditions were not ideal thanks to the 50% Moon nearby - I was able to see and record much more details: the brighter arcs around the central star were not at all visible for me, but now they were easily noticeable. The UHC filter was not neccessary to observe this object, however it boosted the intensity of the brighter central bubble.

Description:
Quite large and bright galaxy that already appears as a tiny fuzzy object in my 8x50 finderscope. Many foreground stars appear over its surface. A feature that resembles a dust lane shows up immediately on the Southern side of the galaxy and after a deeper observation the Northern side starts to display a similar dust lane although it's less defined. As progressing with the sketching a real spiral galaxy starts to appear in front of me, which fact is confirmed after checking astro images after my sketching session - I never look up an object before observation, so my memories about them will not change my vision.
This is a real showpiece spiral galaxy, I wonder why it's so rarely mentioned.

Description:
Perfectly circular shaped globular cluster with gradually brighter core. Can't resolve to separate stars, although there are many faint stars just around it - one of them on the East is actually located on the surface of the GC. I'm not sure whether these faint stars are actual members of the cluster, or simply foreground stars. The Intergalactic Tramp (or more recently called Wanderer, because the word Tramp was a bit politically incorrect) is one of the farthest globular clusters, once believed to be in the intergalactic space, but recent studies prove that it's actually physically linked to the Milky Way.

Ez a nagy, közepesen fényes halmaz könnyedén észrevehető már az 50mm-es keresőtávcsőben vagy binokulárban is. Távcsövön keresztül megszámlálhatatlan csillagot látni, melyek fényessége és szine közel azonos. Némi ködös hátteret is észlelek, amely további rengeteg halványabb tagról árulkodik. A körülmények nem voltak ideálisak az objektum észleléséhez, mivel a közeli félhold jelentősen lecsökkentette az ég határmagnitúdóját (az SQM 17.33-at mutatott a Hold felé, 19.46-ot a Holddal átellenes irányban, -3°C és alacsony páratartalom mellett).

This large, moderately bright open cluster can be detected easily in a 50mm finderscope or binocular. When looking through the telescope I see countless number of stars that are very similar both in colour and luminosity. I can also detect some foggy background which may be miriads of unresolved stars. The conditions were not perfect to sketch this cluster because the 50% Moon caused a low NELM (SQM reading was 17.33 towards the Moon and 19.46 opposite the Moon, -3°C, low humidity).

Leírás:
Hatalmas, fényes nyílthalmaz, a Rák csillagkép közepén. Annyira fényes, hogy még szabadszemmel is könnyen felfedezhető 4-4.5 határmagnitúdójúnál jobb égen. Átmérője a telihold kétszerese, ezért legjobban nagy látómezejű távcsövekben (rövid refraktorok, binokulárok, keresőtávcsövek) mutat. Ez a halmaz számomra kiváltképp különleges, mivel ez volt az első mélyég-objektum amit távcsővel megpillantottam (2001-ben egy 114/900-as tükrössel). Tucatnyi viszonylag fényes fehér és kékes tónusú csillag emelkedik ki a rengeteg halványabb tag közül, némelyek érdekes háromszögeket alkotnak. Az időjárás nem volt túl kedvező a rajzoláshoz, -11°C-ot mértem az észlelés végeztével.

Description:
Huge, bright open cluster in the middle of the Cancer constellation. It's so bright that it can be easily noticed with the naked eye on a sky that has a NELM of at least 4-4.5 magnitudes, as a faint fuzzy spot. It's actual diametre when viewed in a telescope is twice as large as that of the full Moon, therefore it's best viewed in a wide field telescope like a short rafractor, finderscope or binoculars. I've some sentimental feelings about this object, because it was the first deep space object I've ever observed with my own telescope (a 114/900 newt back in 2001). It has some dozens of relatively bright stars with white or a bit bluish colours, some of them forming spectacular triangles. The weather conditions were not favorable for sketching, I measured -11°C when I finished this session.

NGC 2648 (Galaxy)
|
Right ascension: 8h 43m
|
Declination: 14° 17'
|
Constellation: Cancer

Description:
This spiral galaxy is one of the brightest galaxies in Cancer, with a luminosity of 11.8-13m according to catalogues, however to me it looks much brighter than this, with an especially easily noticeable bright galactic core. The almond-shaped star city is small, yet an easy target thanks to the three nearby bright stars.

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.

Description:
This object is also identified as the "UFO galaxy", and resides on the boundary of the constellations Lynx and Cancer. There are no bright stars nearby, which makes finding it a little bit harder, although it has quite a high surface brightness of 9.8 magnitude. The edge-on galaxy of W-E direction has a clearly visible core that seems asymmetric: looks as if it's getting wider Eastward.

Description:
The UFO galaxy, take two. I've already sketched this galaxy back in March 30, 2008 (see here), but because of an unfortunate administrational mistake, I've give it another go tonight. :) The UFO shape can hardly be noticed - if this galaxy resembles a UFO, then we could call all edge-on galaxies UFO's. However, the object is very nice, large and very bright, and the star rich environment makes the view even nicer. Its core brightens up slowly, a starlike core can be barely recognized. It looks as if there was a faint arm to the north of the core. Another interesting point is that although the stars are about at the same spot on the two sketches, the West direction indicator is at really different positions. I should check this out later.

Description:
Small, round spiral galaxy that is slightly elongated to the N-S. Its central region is moderately brighter than its disk. I estimate its dimensions to 1.5x2' with the center shining at about 13.5m and the surface at about 14m. I find the official 11m brightness catalogue data very misleading.

Leírás:
A Rák csillagkép második legnagyobb halmaza az M44 (Jászol halmaz) után. Híresebb társához hasonlóan ez is észlelhető szabadszemmel átlagnál kicsit jobb égen. 71x nagyítás mellett a látómező felét kitölti. Megtalálása könnyű, már a 8x50-es keresőtávcső is fényes elmosódott foltként mutatja. Az M67 egy szép, sűrű nyílthalmaz, tagjainak fényessége nagyon változatos: nagyjából tucatnyi 12 magnitúdó körüli csillag dominálja, de a háttérben sok 13-14 magnitúdós csillag könnyen észrevehető. A teljes általam látható csillagpopuláció legalább száz tagból állt, de az objektum háttere erősen diffúz, így feltételezésem szerint még nagy számú halványabb csillagnak kell a háttérben rejtőznie.

Description:
The second largest open cluster of the constellation Cancer, right after the M44, which can also be seen with naked-eyes even under suburban skies. On a power of 71x, it fills the neary half degree field of vision. It was easily found: even the 8x50 finderscope displays it as a shiny little blur. The M67 is a nice, dense open cluster, with a members of high variety of brightness: there are about a dozen dominant stars of the 12th magnitude, but in the backround you can easily detect stars of 13-14m. The entire population visible to me were at least 100 stars, however the background looks really diffuse, so I assume there must be plenty of even dimmer stars in this cluster.

Description:
Slightly fainter galaxy with an elongation of 1:4 in the SSE-NNW direction. Its core is like a faint, out of focus star. Surprisingly easy to see this galaxy with my little 114/900 Newtonian, with direct vision, although I believe a strong reason behind this is my superb sky in the Zselic Starry-Sky Park.

Leírás:
Érdekes, de nagyon halvány galaxispáros az Oroszlán csillagképben. Mindkettő ovális, a délnyugati NGC 2964-nek nagoyn enyhe csillagszerű magja van, valamint egy főképp elfordított látással megpillantható részletet is tartogat: az északkeleti oldala enyhén fényesebb, mint a másik, és háromszög-szerű alakot vesz fel. Méghalványabb társa, az NGC 2968 semmilyen részletet sem mutat.

Description:
Interesting but very faint pair of galaxies in the constellation Leo the lion. Both of them is oval, the galaxy NGC 2964 to the SW has a very delicate star-like core. This galaxy also displays an interesting detail mostly with the averted vision: its NE side is a bit brighter than the other, forming a triangular shape. Its even fainter companion, the NGC 2968 does not show any detail.

Description:
Tiny galaxy with a slight elongation on its NS axis. Sometimes I suspect seeing its spiral pattern, but it's a very difficult sight with the current sky conditions and the Half Moon lurking nearby. I can see a star to the SE of its center that might be a possible supernova, but unfortunately by checking images later, I find that it's simply a foreground star.

Description:
A very hard catch in the faint constellation of Lynx. I expected something larger based on my map. It's perfectly round, with a definitely denser nucleus. Very faint - catalogues list it between 12 and 13.1 magnitudes, I believe it is closer to the latter. The air is full of dust particles because of fireplace heating in the neighborhood, which makes diffuse details hard to see.
