My astronomy sketches. Hover mouse over image for the inverted look. For fainter objects, take a look at the black-on-white original, sometimes it reveals more details.

By constellation:



NGC 2683 (Galaxy)
Right ascension: 8h 53m Declination: 33° 25'
Constellation: Lynx
Date/time: 2008.03.30 22:00 UT
Equipment: 12" f/5 Newtonian
FoV: 25' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
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.

NGC 2683 (Galaxy)
Also known as: UFO galaxy
Right ascension: 8h 53m Declination: 33° 23'
Constellation: Lynx
Date/time: 2009.04.25 20:30 UT
Equipment: 12" f/5 Newtonian
FoV: 35' Magnification and filter(s): 100x
Seeing: 4/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
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.

NGC 2549 (Galaxy)
Right ascension: 8h 20m Declination: 57° 46'
Constellation: Lynx
Date/time: 2011.05.02 20:30 UT
Equipment: 12" f/5 Newtonian
FoV: 19' Magnification and filter(s): 167x
Seeing: 4/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Tiny, almond shaped galaxy with a star-like core that has a brightness of about 13m, around this core a brighter oval central bulge is also visible. The galaxy is elongated in the N-S direction, at a ratio of about 1:5. SQM reading: 20.96m/arcsec2, 6°C, humid air - as it was raining all day yesterday.

NGC 2419 (Globular cluster)
Also known as: Intergalactic Tramp, Intergalactic Wanderer
Right ascension: 7h 39m Declination: 38° 51'
Constellation: Lynx
Date/time: 2013.02.07 19:15 UT
Equipment: 12" f/5 Newtonian
FoV: 25' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 4/5
SQM: 20.88 m/as2 Temperature: -3°C
Humidity: dry Wind: gusts
Sight: 2 - minor details, somewhat interesting
Difficulty: 3 - moderately visible, dark adaptation needed, averted vision might add to details
Position: 4 - hard, complex starhopping needed
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
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.

NGC 2344 (Galaxy)
Right ascension: 7h 14m Declination: 47° 8'
Constellation: Lynx
Date/time: 2015.01.13 22:30 UT
Equipment: 12" f/5 Newtonian
FoV: 17' Magnification and filter(s): 214x
Seeing: 6/10 Transparency: 3/5
SQM: 20.99 m/as2 Temperature: -4°C
Humidity: low Wind: none
Sight: 2 - minor details, somewhat interesting
Difficulty: 4 - hardly visible, dark adaptation and very dark skies needed, averted vision is required to see details
Position: 5 - extremely hard, difficult to starhop due to lack of stars nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
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.
