NGC 7000 - North America Nebula LRGB

[Han Solo]

Hi, this is my first proper attempt at an LRGB image. I chose the North America Nebula and framed the shot to capture the Cygnus Wall. What do you guys think? Do the colours look good? I think my focus was off slightly for the red channel as the stars look a little bloated?

120mins integration time 1x1 binning.

WO Z73 + Altair 183m Pro Tec + Baader LRGB filters

 

Thoughts, comments welcome as I really want to learn and improve!

Thanks

Really nice, natural look to this 👍🏻How long were your subs?

[Han Solo]

Hey there, R,G,L Subs were 2mins at gain 400. I decided to shoot the Blue at 1min at gain400 due to intermittent cloud cover. I don’t know if that was a good idea or not really.

Nice framing, on Gain i have been advised that for these Sony imx183 chips ( i Have ZWO 183mm pro) , a maximum of 178 should be used as Noise tends come to the fore.

How is it with Unity Gain on short exposures as i have good results on those settings.

Hi Roger,

Thanks for for the information, I wasn’t aware of the gain level being so low. I’ll have a read of the linked post. Thanks.

Unity gain of 400 and black level 50 for the 183 is often recommended too
