I'm not experienced with LRGB imaging, so thought i'd give it a go on M81. However, when i combine the 4 individually processed integrations i end up with horrible colour hues across the image - they're all aligned and wotnot. Am i running into the issues of light pollution (inside the M25), which i can only remove with aggressive DBE application? Individual files attached.
I've got a 5 year old desktop, which i think performs decently and does my Pixinsight processing pretty well. However, i want to change to a laptop for the form-factor, but i don't want to compromise on performance.
This is my rig: https://www.userbenchmark.com/UserRun/27054387
What machine do you use and how does it perform with Pixinsight? Any folk familiar with computer hardware able to provide steer on whether i'm due an upgrade?
Looking to understand how others do their processing.
Hi, I have taken mono LRGB images of M51 with my new ASI1600mm-PRO.
I have a mix of 30s, 60s, 120s subs. 100 darks, and 100 flats for each filter. About 4 hours total.
I Used DSS for alignment and stacking, then Pixinsight for LRGB combination.
My issue is that i'm not happy with the colours, the stars all appear white and the background is strange.
I have attached the Aligned LRGB images.
Can anyone point me in the right direction? Thanks!

I recently posted a picture of B33 using my Optolong L-Enhance filter which was not too bad, a bit red, for my first time trying out Pixinsight. Last night I managed to get nearly 2 hours using my IDAS D2 LPS filter and after watching many Youtube videos I've managed to get the following using my Esprit 100ED and modded canon 450D, 21*300s Lights, flats, darks and bias frames. I think I'm starting to get my head around post processing.
