NGC 2903 Spiral Galaxy in Leo.
LMV: 6.9 - 7.2
RA 9h 32.2
XT10, 13mm Stratus with 2x barlow; 92x & 184x
Shows a bright inner core that is star like at first but with averted vision came out quite strong. Dust lanes/mottling evident with a strong lane that came and went with conditions in the center of the galaxy. A strong halo around the core that diffuses as it goes toward the edge. Hint of two arms are evident at either end. Sorry, I noticed I did not put my cardinal points on this. The galaxy sits north-south if I remember right. I'll check that tonight (it was my last item of the night). As Mark has noticed, it you are on a laptop and tilt the screen you should see more or less detail.
Charles Messier missed this by only by a small amount when completing his catalog. Three times he had comets he discovered come quite close to this object. William Herschel discovered it on November 16, 1784. It is estimated to be 20.5 million light years away.

Thank you for sharing this great sketch! NGC 2903 is one of those galaxies that I've kept missing, too - much like Messier. Maybe later this spring with the next new moon cycle I'll try to catch this bright little galaxy.

This is a very, very nice sketch of this easy to locate galaxy in Leo.
I did get a good look a few nights back but no sketch for me.
