The Iris Nebula in RGB

NGC7023 Imaged over two nights and plagued by satellite trails. Imaged before moon rise on Monday 29th and Tuesday 30th nights. Exposure times were 8x 900s in Red 8x 630s in Green 8x 820s in Blue. Tricky one to process, pushing it so close to the noise levels really brings out faint gradients. Processed in Photoshop.

Looks pretty good to me Peter. Nice vibrant colour and you've bought the dust out well.

It’s come out really well, faint dust really requires a lot of integration to get a clean result butyouve done well.

Dust has come out very well, lovely dark blotches and dust extensions across the image.

John.

Thank you for the encouragement ....Im pleased with want I have especially for just over 5hrs total exposure ... I was going to carry on and get some more frames but the bad weather has set in again it doesnt look good for the next couple of weeks here...by that time the moon will be getting bright.

Lovely result Pete, although perhaps a tad more noise than you would like, it never the less still shows that mega data is not always needed to get a pleasing image, especially with 12" of aperture and at F3.8

This area reminds me of our southern beauty, the Corona Australis dusty region.

Fine image.



If you are worried about noise, I'm sure a little judicious noise reduction of the linear frames using Pixinsight wouldn't hurt the detail.

Thank you for the feedback....the small version does look noisier that it actually is...the full res version isn't too bad....The plan is to get more frames which should help with it.
