Title: NGC6888 Ha From Home
Post by: RobertM on Jun 10, 2011, 09:50:49
Been meaning to revisit this with a bit more resolution since my last effort with the Sky90 and SXV-H9  Curiously the SW MN190 + ML8300 has almost exactly the same field of view so I'm not quite sure it was worth the extra effort.

This has been more heavily processed than the HS image I just posted which has had virtually no processing other than simple levels and curves.  Even so it's interesting to compare the two - I'll let you draw your own conclusions.

Optics: Skywatcher MN190
Focal length: 1000mm
Focal Ratio: f/5.3
Camera: FLI ML8300
Filter: Baader Ha
Scale: 1.1 arcsec/pixel
Subs: 3 x 600s + 24 x 600s (4.5 hours total)
Location: Orpington
Date: 05-06/06/2011
Imaging start time: 23:00

Fantastic image!

Maybe the best H-alpha image of this I've ever seen.   Lovely big scale with excellent detail!
