ASI585MC Amp Glow?

hughes

I'm getting a light area on the right side of my dark frames as well as slight light "spot" in the lower right corner. This also shows up in all the light frames. Is this normal? Do I have a defective camera? It's not a light leak, the cap was on the camera. For some reason this is difficult to process out as the calibration tends to over-compensate and I end up with a dark spot in the final image. Attached master dark and Image processed in ASIDeepStack. Stretched to clearly show the spot and right edge gradient.

Thanks

It could just be light leak somewhere in your imaging train.

Sorry, FITs files seem to be too large to upload on the forum.

hughes You can share it via google drive or other cloud drives.

Thanks. I opened a support ticket and emailed the master flat file. Please let me know if you need anything else.

Thanks. I've found that the camera cap can let some light in. I've been able to solve the problem by just leaving the darks out of the calibration.

The 585 definitely need darks if uncooled. Both of my 585's show exactly the same bright areas as yours. No light leakage here.
