NGC6888: The Crescent Nebula Widefield (Ha)

[Euan]

I still have a few gremlins to sort out before Kielder, a bit of tilt that I can't seem to track down and a weird spike effect in DEC that is causing it to guide slightly worse than in RA

Despite this I managed to squeeze a quick two hours Ha on the Crescent Nebula. I've never imaged this area before and I'm surprised at how much nebulosity there is, a mosaic could be on the cards here

Superb focusing and tracking. Very nice processing too.

I like it a lot !

I think I love the background of the crescent more than I love the crescent, and this shows it off to the full!

Wow, I had no idea there's so much nebulosity! I'm planning on having a go at this myself but I'm going to have to rethink my plan - a mosaic is a definite!

Very, very nice

Another superb Ha Image .

Totally agree, but the Crescent is really singing in this rendition and just 'hanging there' in space. I love that 3D look. Splendid picture.

Wot a lot u got! That 383 is starting to earn its keep i'd say

Nice shot Euan, very well presented.

Shocking(ly good).

This one really appeals to my "mono" sense a great deal. Such amazing detail.

All said above . Excellent shot . Regards , Trevor

Thanks for the comments. I've gave it a bit of a re-do I was getting carried away with the Dark Structure Enhance in PI and it was clipping a bit of detail

I got 7 x 20mins of O3, which I've tried to make a bi-colour with, but the moon was too bright and the O3 data was rubbish, hence the puffed up stars to try and push it a bit more

It's hard going this narrowband lark!
