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 5466 (Globular cluster)
Right ascension: 14h 6m Declination: 28° 29'
Constellation: Boötes
Date/time: 2009.04.25 21:00 UT
Equipment: 12" f/5 Newtonian
FoV: 34' Magnification and filter(s): 100x
Seeing: 4/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This globular cluster is located in the constellation Boötes. It's quite bright with large apparent size (I estimate a diametre of about 8'), however unfortunately it has a more spectacular neighbour, the M3 that draws attention away, although the two have similar size. About a dozen of its stars can be separated easily with direct vision, and the whole surface is very grainy with a lightly brightening core.

NGC 5529 (Galaxy)
Right ascension: 14h 16m Declination: 36° 10'
Constellation: Boötes
Date/time: 2010.05.12 23:25 UT
Equipment: 12" f/5 Newtonian
FoV: 23' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Very thin edge-on galaxy. Although it can be detected with direct vision, I can see its real shape and size using averted vision. By looking far beside it and a bit away from the eyepiece it seems as if it doubles its extent. To the East of the galaxy an interesting triplet of stars can be found which is quite noticeable to help to locate this object. I estimate its surface brightness to be around 14.4 magnitudes, with its core a little bit brighter. To the East there's a very faint star of 14.8m that sometimes seem to be inside the galactic body.

NGC 5857 + NGC 5859 (Galaxy)
Right ascension: 15h 08m Declination: 19° 33'
Constellation: Boötes
Date/time: 2009.06.13 22:00 UT
Equipment: 12" f/5 Newtonian
FoV: 23' Magnification and filter(s): 167x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

An extremely faint pair of galaxies in a sparsely populated starfield, therefore it's recommended to have some experience with starhopping. The brighter one is the NGC 5859, that is a small edge-on galaxy. Its core is brightening slowly. To the NW you may notice a small foggy star which turns out to be the core of another faint galaxy, the NGC 5857. It's much fainter than its companion, and features a star-like core. It nearly touches the outer regions of the NGC 5859. The faintest star of the sketch is catalogued at 15.21m, which is considered to be excellent in such a terrible atmospheric conditions.

NGC 5899 (Galaxy)
Right ascension: 15h 15m Declination: 42° 0'
Constellation: Boötes
Date/time: 2010.05.13 0:20 UT
Equipment: 12" f/5 Newtonian
FoV: 24' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Tiny, extremely faint object. The core is barely brighter, not starlike. I estimate an average visual surface brightness of 14.6m and a dimension of 2' x 0.8'. Unfortunately the bad seeing is not ideal for its observation

NGC 5689 (Galaxy)
Right ascension: 14h 36m Declination: 48° 42'
Constellation: Boötes
Date/time: 2010.06.05 20:00 UT
Equipment: 12" f/5 Newtonian
FoV: 24' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Medium brightness, small galaxy, elongated in the E-W directions, it's shape reminds me of an eye. Its Southern side looks a bit brighter near the fuzzy star-like core. The core is only slightly brighter than the rest of the galaxy and I estimate it to have a brightness of about 13.9m. The air is very humid.

NGC 5707 (Galaxy)
Right ascension: 14h 38m Declination: 51° 31'
Constellation: Boötes
Date/time: 2010.06.05 21:00 UT
Equipment: 12" f/5 Newtonian
FoV: 15' Magnification and filter(s): 250x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Very tiny and faint galaxy, I find it a definitely hard object. At 71x all I can notice is that next to a bright star there's some star that looks a bit fuzzy. By increasing the magnification the surface of the galaxy slowly becomes visible. I find it a lovely little galaxy and a real challenge!

NGC 5875 (Galaxy)
Right ascension: 15h 10m Declination: 52° 29'
Constellation: Boötes
Date/time: 2012.06.16 22:45 UT
Equipment: 12" f/5 Newtonian
FoV: 15' Magnification and filter(s): 250x
Seeing: 7/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Small and very faint galaxy, elliptical by direct vision, but seems lentil-shaped by averted vision, bit more shiny to the SW side. With averted vision its core looks star-like, but it's only a little bit brighter than its surface.

NGC 5876 (Galaxy)
Right ascension: 15h 10m Declination: 54° 28'
Constellation: Boötes
Date/time: 2012.06.16 23:20 UT
Equipment: 12" f/5 Newtonian
FoV: 10' Magnification and filter(s): 300x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Very tiny elliptical galaxy near the galactic companion NGC 5874. According to my map the latter should be brighter, however that is almost invisible while this one's definitely visible already with 71x power. It has a tiny star-like core. Lies in a trapesium asterism. It has a perfectly even surface except for its core.

SQM reading: 21.3 MPSAS, 13°C.
