Usually I have no problems with WBPP. Now I am getting thses "three dimension" rings.

 

 

 

Luminance channel. Using ASI2600MM Pro. 

Stacking with Bias frams (50), flat frames (30).

After stacking, gradient removal using GraXpert and stars removed with Starxtermminator.

The rings match the flat pannel dust rings.

 

I tried using 100 and 300 for pedestal without any difference in the results.

 

Any ideas?

 

Thanks!

The embossed look like this usually means that the dust motes have moved. But you have so many, which makes me think that the whole filter has moved. I've seen something like this happen only once when I momentarily lost power to my rig. The filter wheel is supposed initialize and put itself in position 1 (Lum for me,) but something went wrong with that. Doing a single full cycle of filters fixed it. Also, do you have the option for unidirectional movement turned on in Ascom properties?

Try processing it without the flat.  If those patterns go away, at least you know that it's a flat issue and maybe is the issue above.  Try reshooting the flat.

 

I doubt this will help, but you may also want to try resetting WBPP to its default parameters and try again.  In general, this is always a good thing to try if things come out wonky.

I've seen something like that with my ASI2600MM. It was related, for some reason, to using darks. I stopped using those and the pictures greatly improved.
