Description

M3 - Mag. 6.3 Globular cluster in Canes Venatici.
25 x 180" light frames
15 darks
15 flats
30 offset/bias
ISO 800
Waxing gib. moon - so not ideal conditions - but thought I'd take a stab at it anyway as nice nights have been rare lately. Looks like I might have been able to get my focus a little tighter.
This was with Cel. .7x focal reducer. Maybe I'll try it again at native FL and see how that looks.
This was my first shot of a glob... any comments and criticisms are most welcome!
Thanks for looking!
