I am currently going through the process of trying to get a good process of my panorama. Had another go at it this afternoon, this is a 10x9.
Issues that I am aware of are:
Banding - Trying to figure out how to remove this, having serious difficulty in figuring this out. The banding is imprinted into the background and at different levels in each frame depending on how close the signal is to getting over the read noise (banding is created on sensor readout).
There is also some banding moving through the middle of the image, same thing. Low signal area; lots of black.
Satellites - This is my very last thing I will be removing. Going to do it on the small handful of frames individually as a final step.
Blue cast - (along the lower two panels and in the middle a little) This is a consequence of the banding, the lower three panels (I haven't included the first panel at all) which have the lowest signal of all of them. Will be dropping the lowest and maybe both, not sure yet.
As a final attempt I may end up trying to rectify this in PS but that won't be on the individual images like everything else.
What I am unsure of:
Mostly colour at this stage. I was at a friends place last night for dinner and asked his opinion (on my non colour calibrated laptop) on colour when I was doing some pre-processing testing. He has no idea on astro colour btw, I was mostly just asking whether the upper region was golden speckle without any random colour casts
I still want to go and attempt to do some contrast enhancement on the black regions (dust) to make them pop more but one thing at a time. Just needing some clarification to see if I am on the right path now before moving further on in processing.
