ooooh, its my first post.... Hello! ( long time lurker, regular reader, hoarder of good things from FLO )
So I have dived into monochrome imaging - I'm shooting on a Qhy268 m with Antlia V-Pro LRGB filters and in this case im using a Starfield 102.
I have stacked and processed the L,R,G and B channels separately in Pixinsight using the Weighted Batch Preprocessing script. I'm getting no rejected frames and each channel has its own set of calibration frames. L,G and B each take around 15 mins to process, but R takes closer to 2 hours.
The following image shows the result of these stacks with a single STF applied to make them visible. As you can see, the R channel ( top right ) is really oversaturated which obviously doesn't work well when I combine the LRGB. I've tried rerunning WBPP but the result is always the same.
Any thought or suggestions? Am I missing something obvious in Pixi or could it be something more fundamental like a back to front filer ? ( they are 36mm unmounted )
