A few days ago while going through one of my backup drives I found some data that I'd calibrated and briefly looked at but never processed so I figured I'd have a bit of a play.
I've been doing some non-scientific testing between PixInsight and AstroPixelProcessor and Bayer Drizzle. Between the two of them, APP is growing on me because it can be more click and forget for a while. I'm not a fan of PI BPP as it doesn't allow a lot of tweaking so I find myself doing everything manually. I will continue to do all of my calibration but I am thinking I may do my stacking in APP and then subsequent processing in PI again.
First off I have some data taken over two nights 3 months ago with my unmodded Nikon D810 and Sky Rover 130mm.
Processing has been nothing other than colour calibration, MaskedStretch and then a slight histogram stretch to brighten the field and then some arbitrary saturation.
NGC 2070 RGB
This afternoon I remembered that I had some OIII and Ha data on my laptop from this region and thought I'd have a play in combining the two together. Attempted combining the Ha and OIII into the RGB while in linear and wasn't happy with the complete abolishing of the fainter stars with nebulosity.
Decided to do something that Placidus suggested a while ago and that was to combine after stretching. This is what I ended up with, processing was the same as with the RGB, just colour calibrating, stretching and saturation.
NGC 2070 HaRGBOIII
I'm reasonably happy with how the narrowband and RGB have combined together.
