Saturn Nebula
SPX350 F9 with 2xPM, Mintron (GStar-Ex), Baader RGB, Astronomik UHC.
Gave this a quick go and the UHC filter again showed iteself to be better than Luminance for contrast and structure letting through 30nm blue green and 50nm red light. The two ansae with red tips showed well.
UHC-60mins
RGB-7.5mins each all 2.56sec subs.
Thanks, John.
