Heart nebula 7.5 hours
This is my latest picture of the Heart nebula. I spent three nights photographing this target, but I ended up using data from only two of them, because of a background gradient caused by the moon during one of the nights. I found it quite difficult to process the image with the gradient, so I decided not to use the data. I think 7.5 hours total is already quite a lot. I would love to do one more session just for the stars with an uv/ir cut filter, since the Ha/OIII filter makes the stars look quite unnatural.
One of the things I found challenging was manually framing the target as similarly as possible each night with the Skyguider pro. I am really looking forward to getting a proper GoTo mount.
Another thing that was quite difficult to deal with was the background when going for this false color look. There's still some blue in the background, that was hard to get rid of. This seems to happen to me every time I make a false color image.
Lastly, I think the stars are probably the weakest part of the image. I kind of gave up on them knowing that I will hopefully replace them with better ones soon.
I'm still a beginner, so any feedback is appreciated!
Equipment:
* ToupTek ATR533C (gain 100, offset 45, 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:
* 153 x 180s lights
* 15 darks
* 40 flats per night (2 nights total)
* 30 dark flats
* Bortle 8
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 and BlurXTerminator
* Pixel math to create one colorful image (R=Ha, G=0.1\*Ha+0.9\*OIII, B=OIII)
* StarXTerminator
* Color calibration
* NoiseXTerminator
* StarXTerminator
* Modified arcsinh transform with even weighted luminance
* Generalised hyperbolic transform
* Black point to reduce background
* Saturation stretch
* Negative transform, remove green noise and negative transform again
* Curves adjustments
* Stretching the stars image
* Desaturate the stars image
* Star recomposition
* Final adjustments on phone
