Ok not bad just need to balance the green out of the background you look like you've overdone curves on the larger image

One of my favourite galaxies. Shame the FOV isn't that bit bigger to fit in those other nearby galaxies.
Nice work.

If you look carefully you can still see Supernova 2011ja which went of in this galaxy late last year.
See Here .
cheers

That's a great result but I bet you wished you'd taken more subframes?
I would like to try this one too.
Thanks for posting.

The small was made from the large with just a resize. The large and small images should be the same. I must see why there might be a difference. The small was saved at a higher compression but it shouldn't alter the colour?

Of course I was shooting for a number of targets to see how the RC would handle them and went for longer exposures with M16 (already up) and M20 (yet to be processed). Still I like what I see so I will definitely come back for more subs with this one.

Thanks Ross and to you all for the interest and feedback.

Stretching an image induces noise etc which isn't as easy to decern in a smaller image because it's so small, your eye can't take in enough information to know what is out of focus etc, so you brain conjures up an image that "feels" sharp!

If the image is bigger, your brain can see the artifacts and in the larger image these are apparent
