Another great shot of this Summer favourite. Yes, it was a clear night for a change with a few hours before the Waning Gibbous moon rose to spoil the show. I was out there too, shooting the same target. I got less than 25mins of RGB and 24mins of Ha as the moon came up, so not a patch on yours. Well done Steve.
Compared to some of the other HH images doing the rounds at the moment, I think I was a bit heavy-handed with the processing - as evidenced by the missing streak of H-Alpha that gives the 'mane' within the horse's neck. (Check Peter's image and you'll see what I'm referring to.)
Looking like a very good image there.
Just a suggestion here, but have you tried just using Bias fames instead of Dark Flats?
So you end up with Lights, Darks, Flats , Bias
Top image though.
I don't use bias frames because the '183 doesn't cope well with exposures under 3 seconds. I have tried them in the past, and they do not work very well at all. A bit of research showed a lot of other people with the same problem, so I followed their advice and started using darkflats. So far, they've worked really well.
Me not so lucky!!
