Steve's Notes

===== NGC 685 30" (11/4/10 - Coonabarabran, 264x): bright, large, slightly elongated ~WNW-ESE, broad concentration with a large brighter core, 3' diameter. Just outside the core, the surface brightness is irregular or mottled and a couple of extremely faint quasi-stellar knots (HII regions) are just visible in the outer halo. There is an impression of spiral structure in the halo, but I couldn't trace the arms.
