By constellation:



NGC 1023 (Galaxy)
Right ascension: 2h 41m Declination: 39° 7'
Constellation: Perseus
Date/time: 2010.01.03 19:45 UT
Equipment: 12" f/5 Newtonian
FoV: 11' Magnification and filter(s): 167x
Seeing: 7/10 Transparency: 2/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This galaxy shows an almond-shaped bright core and an ellipse-shaped body, with some brighter bulge around the core as its only special feature. The NELM was quickly getting worse because of the rising Moon, so I'm absolutely sure it would show a much larger size under a truly dark sky, but this time I estimate dimensions of only 2'x0.5'. SQM readings (just to give you an idea how much the Moon adds to light pollution): 19.95m/arcsec2 (Moon slightly below the horizon) down to 19.58m/arcsec2 (Moon slightly over the horizon) just within a 30 minute timeframe.
