294MC Pro amp glow calibration issue

MatFayden

Hello everyone!
I recently purchased the ZWO 294 MC Pro camera, which exhibits a significant amp glow issue. I've heard from many people that this problem can be effectively eliminated using dark frames. However, after stacking and calibrating with dark frames, I still have a persistent blue glow in the area where the amp glow used to be. What's surprising is that the dark frames seem to perfectly calibrate the R and G channels, but unfortunately, they don't address the amp glow in the B channel, resulting in this persistent blue glow. I'm confident that my dark frames are prepared correctly, so I'm starting to wonder why the problem remains unresolved.
If any of you have any ideas about what might be causing this phenomenon, please, I would appreciate your help. Thank you in advance for any suggestions!
(Below are screenshots of the stacked images and individual channels.)

MatFayden Could you share some darks and lights of B channel frames with us? we will check it, thanks.

I used MC camera so its RGB image, I just split it into channels.

Here are my lights and darks: https://drive.google.com/drive/folders/1zJT0VZ5vl2FrSROxY48Ekgcs6HnT3FSG
I took them at 10C, but the temperature makes no difference, since my second set of data at -10C and darks also at -10C still had the blue thing after stacking.

Tech@ZWO Hey, did you manage to to solve or find the cause of my problem?

Tech@ZWO

MatFayden I'm still looking into this problem.

The problem is probably with the light frames, The G channel has more data than the R and B channels in usual, but the B channel data is the most in all your light frames, which is strange.

Could you tell us what device you use and do all light frames have this problem?

MatFayden

Tech@ZWO Like I said, I used ZWO 294 MC Pro and yes, all light frames have this problem.

Tech@ZWO I used L-Extreme filter. Maybe it has something to do with this problem.

Tech@ZWO

MatFayden Probably yes, remove the filter to see if the problem disappears.

Tech@ZWO whole amp glow almost disappears without the filter, but I've seen many amazing pictures with 294mc and L-Extreme, without encountering any issues like the one I'm experiencing.

Tech@ZWO So I took some pictures yesterday, but now with 121 gain and the results are the same 🙁

Hey MatFayden. Had the same issues before with this camera and the l-ultimate filter and in my case my darks were faulty. Took new darks in the fridge beacuse my rooms aren´t dark enough and it works.

Hope this will fix your issue too.

PS: Can´t upload images to show you the differences and issues.

This was my result with the old and faulty darks:
