Barnard 92

I needed a subject that I could shoot all night around my trees and such, as I am not fully automated yet.

So, my first stab at a dark nebula was in order. Here is Barnard 92, 28x5 min.

I tried a bunch of 10 minute subs too, but I need a narrower H-a filter; the background was really high on those, which really ate into my dynamic range, so I just used the 5 minute data. The full moon and clouds of smoke from fireworks didn't help the 10-minute subs, either.

I had to clip the dark end, otherwise the nebula is too noisy.

Lots of stars in this region, sheesh!

Alec, it looks good despite the troubles!

Thanks for the comments, guys.

Here is another version of the 5-min subs, with the dark not as clipped. See the noise in the nebula proper?

Is this better?
