My amateur interest in astronomy brought out the term 'magnitude,' which is used for the brightness of a star.

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 3938 (Galaxy)
Right ascension: 11h 53m Declination: 44° 3'
Constellation: Ursa Major
Date/time: 2011.05.02 21:15 UT
Equipment: 12" f/5 Newtonian
FoV: 42' Magnification and filter(s): 71x
Seeing: 4/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
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.
