NGC 7000 in false color

This is the picture taken with my new ToupTek ATR533C. So far, I am really happy with that camera. I have only used a stock DSLR before, so the upgrade was drastic. I wanted to do 300s exposures, but it was almost full moon so I decided to do 180s ones instead. Right now, I am happy that I did that, because probably I did my polar alignment inaccurately and even on the 180s exposures I can see star trails. The original picture was Ha dominant so I decided to try to process it in false color.

This was my first time trying to process something in false color and I think it turned out beatufully. I am still learning so any advice is appreciated.


Equipment:

* ToupTek ATR533C (gain 101, offset 40, cooled to -10)
* Askar FMA180 Pro
* iOptron skyguider pro
* sv220 7nm Ha OIII dual narrowband filter
* ToupTek GPM462M guide camera
* SvBony 30mm f/4 guide scope
* Mele Quieter 4C

Acquisition:

* 60 x 180s lights
* 50 darks
* 50 flats
* 50 dark flats
* Bortle 5, almost full moon

Software:

* NINA
* PHD2
* Siril

Processing in Siril:

* Stacked in Sirilic which created monochromatic images of Ha and OIII
* Processed Ha and OIII separately using Graxpert background extraction and Cosmic clarity sharpening
* Pixel math to create one colorful image (R=Ha, G=0.6Ha+0.4OIII, B=OIII)
* Starnet star removal
* Modified arcsinh transform with even weighted luminance
* Generalised hyperbolic transform
* Black point to reduce background
* Syqon prism denoising
* Star recomposition
