Gonzo started following M45 , NGC 7635 (re-processed) , Weird "amp glow" looking on an 533MC and 1 other

NGC 7635 41x300s Redcat51,CEM25p, 533MC (U/V filter). I have reprocessed the data, using better flats and a better use of the starnet.

It was the OAG stick... with the stick backed out: with the stick where it should be (in this test, I did not align the prism with the main camera sensor)
-
yeah, at least it's not an issue with the camera. Just me doing something wrong.

This is a Siril stack of 41x300sec and I get this on the side, it looks like amp glow but the 533MC does not have amp glow. The camera/scope/mount was in a dark place with no direct light or ambient anywhere near it, it's always on the right side of my images. This time it's really present. Not sure if I'm doing something wrong with my Siril processing.

Redcat51, 533MC (u/v filter only), CEM25p, Siril processed (using 1.2.0). Messed up something at the Star recomposition stage and lost my previous stretching (it was nicer than this). 41x300s (+darks+biases+flats), bortle 4 location If you zoom in, you can see the bubble 😁

It should be for the next 3 nights, I'll add more data to it.

Before I took M45 I was on M31 for about 4 hours but something went wrong with the mount so I switched over to M45 and only got 50 min, I was getting tired and needed to go to bed.

I feel that I could have pulled more of the dust clouds for 300 seconds frames, I would also like to know how to get the actual background more dark. The image feels a bit washed to me.

M45, RedCat51 + 533MC + CEM25p[unguided]... and a very crappy process with Siril. 10x300sec lights + 25 of darks/bias/flats

@ONIKKINEN This is what I came up with, using the Asinh transformation tool and following your "Start processing with a crop, a background extraction, colour calibration and a stretch (in that order)" It really does look way better now (I think) than the one I've posted at the start of this thread.

Thanks for the detailed response, I shall try the Asinh transformation tool. Overall I'm quite happy with the capture, but I do need to get my main computer sorted out to be able to work with Pixinsight and on a large monitor instead of the laptop...
