I've just begun the process of imaging Jupiter with the following setup:

8" f4 Skywatcher Newtonian
4x Powermate
ZWO ASI462MM
Astrodon 1.25" Gen 2 E-Series CCD RGB filters

The goal was to use what I had (the Newt and the filters) plus a few extra things (Powermate, camera) to capture planets, despite the smallish aperture.

I've been imaging using Sharpcap and get around 100fps for 45s, using a small ROI and hitting around 80% on the histogram for each channel. I use Sharpcap's solar system sequencer to get three RGB runs in a row, with a focus set before I begin (hard to see any difference with focus between each filter). I've then been running the Mono8 SER video files through Autostakkert, Registax (wavelet sharpening) and WinJUPOS. I use regular Derotation on each channel (Red, Green, Blue) and then RGB Derotation on the complied Red, Green and Blue images (saving images as TIFFs). It seems I'm getting some rather odd colours (see image), particularly in the dark bands. I wonder what might be causing the pink/maroon colour? Registax RGB balancing doesn't solve this and I've been working around it using a red colour mask in PixInsight, upping the green and lowering the blue.

The Astrodon filters have a clear gap between the Red and Green transmission peaks (to avoid light pollution) so I wonder if this lack of cross over is to blame? I've seen other images using Astrodon filters that don't seem to have this issue however, but have also heard mention, via a very imformative YouTube video, that Astrodon filters don't perform so well on planets. Perhaps for this reason? I've attached each sharpened RGB channel if that helps?

Would love any thoughts on this. Maybe I'm doing something wrong or missed a setting somewhere? Cheers.
