Hi Robin,
Just read an intriguing article on the Siril website here:
https://siril.org/2021/12/enough-with-dark-flats/
about using a constant instead of a dark or bias image with flat frames. Was wondering if this is something that can be added to the 'Capture Flat Frame' routine - say 'Capture and Subtract Constant' with maybe a routine to determine the constant as described in the article? Might simplify and speed up flat frame capturing with many cameras.
Also, it would be good if there was a 'cancel' button on the flat frame capture routine - I've had trouble stopping it when needed (have to kill SharpCap to do it). Thanks for your consideration!
Syntheic Bias for flats?

Re: Syntheic Bias for flats?
Hi,
yep, that makes sense - in fact if the camera has a sensor analysis done then SharpCap already has all the data needed to work out the bias level for any given set of offset/gain values. The only problem comes if people have used the image manipulation controls that some cameras have - white balance, gamma, contrast, etc - those will throw off the calculation of the bias level, but a bias frame would work.
Another thing would be to blur the bias frame to remove noise from it - that might help a little too.
thanks for suggesting,
Robin
