Re: Live Stack with Flat Frame Bug?

An update to this issue:

I am getting better flat correction with the ASI294 using mono-bias with image controls set to Red 50 & Blue 50, zero for brightness/offset and exposure around 1/4 sec, and gain adjusted for exposure between 120>300. When capturing images I balance the color as best I can first in Image Controls for the specific exposure settings and calibration frames. Unfortunately ZWO still has not provided drivers that allow light pollution filters to AWB using the Red and Blue settings in Image Controls; the red channel is always set to max and still is not enough. I use Idas LPS D1 and also Idas LPS P2 filters, which are noted to be some of the most neutral LPS filters.

Additionally there is less of an issue and flats appear better when there is less vignetting which generally occurs when I use my scopes in native format without focal reducers.
