Object name: NGC6503
NGC 6503 is a nice flocculent galaxy in eastern Draco and thought to be about 17 million light-years distant based on HST images of its red giant stars. Most sources call it a dwarf though NED doesn't. Nor should it in my opinion. Most sources give its diameter at 30 million light-years. I find that quite wrong. That is the diameter of its brighter disk but the disk extends considerably further both directions in my data. I find it nearly 10 minutes of arc across which makes it 49,000 light-years across. The faint extensions appear full of fuzzy objects. Since the HST image doesn't begin to go out far enough I don't know what these may be. Likely star clusters I would think. Some may be globulars I suppose but they seem to be in the disk making that unlikely. This is a very active galaxy with an active core and many star-forming HII regions. It was discovered on July 22, 1854 by Georg Friedrich Julius Arthur von Auwers using a 6.2" telescope.
