Improving NGC7331.

[ollypenrice]

In the original version of NGC7331 and the Quintet, posted a while back, I had 14x15 minutes of luminance. Since 7331 is quite small (10x4 arcmins ) I had to push the processing pretty hard to sharpen up the details and, seen fullsize, this showed. We decided to add the same again in L to see if we could sweeten it up a bit. This is a crop.

The whole thing now looks like this:

Small improvements take a long time in this game!

PS This was with TEC140/Atik 460 mono and Mesu 200 mount.

A very impressive result.

Your original image was what inspired me to have a go at Stephan's Quintet at 2800mm posted last week - but even your original image at around one third of the FL seemed to show more detail than mine.  Now this one is even more smooth.  That TEC140 is certainly a capable scope.  Apart from the processing skills......

Spectacular.

Wow Olly, that is my kind of shot, just superb.

I have to confess I prefer galaxy vistas like this over nebulae every time, must be something to do with the scale of the universe....

Awesome image! I have fond memories of first spotting Stephan's Quintet through your 20" Dob. I should also have been paying attention to those little fuzzies above NGC 7331, it seems

well mine of that area was not nearly as good as this one   I have a long way to go  

[Allinthehead]

Beautiful.

That's got to be one of the most amazing sights in the night sky, and gloriously captured and processed.  I keep debating with myself just how much luminance data to capture.  I invariably lose the debate.

Great image, Olly. I think that one of the things to strive for when imaging this group, is to resolve the arms of NGC 7340 (the leftmost galaxy above NGC 7331), and resolve the star and the galaxy's core. Both those boxes are ticked, end then some.

Putting that TEC under dark, clear skies helps. A little.

I just love the unusual composition Olly, with so much going on all around and nothing in the center.

Be fair to yourself, Peter. It's a debate in which you're up against a formidable opponent...

It's a simply gorgeous field of view - beautifully done.

Exquisite work Olly: harmonious colour, composition, processing . . . top drawer!
