Crescent nebula NGC6888

Recommended Posts

This is "sort of" a reprocess from November 2018, except I didn't use the full frame at that time, so this is the first full frame process.  I think I cropped it because I wasn't happy with the corner stars, and wasn't all that pleased with my processing of the outer nebulosity, so decided to give it another "go".   Still not 100% happy with those items, but it's a lot better than previously, but probably doesn't bear close scrutiny. 

Ha 12 x 600
Oiii 7 x 300 binned
RGB stars R x 3, B x 4, G x 4 (all 150secs binned)

Atik460EX & WOZS71 + FR x 0.8 HEQ5

Slightly tweaked image, converted to starless and put major stars back in to try to get rid of those tiny background stars.

Done a bit more tweaking as wasn't happy with those background tiny stars (see earlier version).  So did a starless version and then put the stars back.

Very nice indeed Carole.I especially like the way you have captured the surrounding area of Nebulosity.It really brings it out.

I,m torn between the original and the last re-process without the stars.

Either way its a really good capture.

Mick.

I think the first image justs romps home in 1st place,for me anyway.

My preference is the first version, I think that the stars almost look like noise when they have been reduced in the second version.

Third version for me.

Lovely image, and I like the FOV/ framing.

Still Trevor.  Still got your ED120.  Don't use it all that often now though as I have a dual rig with ED80 which gets most use - been toying with selling it, but keep thinking I'll regret it.
