This is NGC7023 aka the Iris Nebula, a bright reflection nebula in Cepheus. NGC7023 refers to the open cluster inside the nebula. The entire is also known as Caldwell 4.

 

Imaging is a total of 3 hours RGB, with a small amount of Luminance added, captured from Bortle 2 Kerry Dark Sky Reserve on 20th July but unfortunately with no astro darkness.

 

Imaging: Esprit 80, ASI160MM Pro @ -20C, gain 139, Baader RGB filters.
Guiding: Starwave 50mm, ASI290mm Mini, HEQ5 Pro belt mod.
Capture control: NINA, PHD2, SharpCap PA.
Processing: APP, Gimp, Noise Ninja.

I love the IRIS Nebula, I have been imaging this target ever since i started the hobby about a year ago, I need to let go, i always think i can get a better image of it next time i go out. I love this image, every time i see a great image of the Iris Nebula i just have to have another go, you've done me no favours. 🖖

Thanks @Carastro, I did take some L data (25mins) but it tends to wash out the RGB colours, and in particular I lose those dark clouds as the detail isn't really there in the L. I'm assuming that I just haven't got enough L data to form the basis of an LRGB image. I may come back to it if we get another clear night, and grab a few more hours.
