Hello,
What could be the reason I'm getting a "CRITICAL WARNING: flat-field calibration can not be performed correctly!" message?
I'm getting this message even though the flat and dark flat files were taken with the same equipment on the same night. Is there a way to troubleshoot this error and does it have an influence on the final stack? I'm not using any Bias frames.
As a reference, refer to the attached image.
When you load a flat and darkflat; do you see it having the same ISO and such?
I am also seeing this message. It is true that I am not using a bias frame, HOWEVER I am using a flat frame generated by SharpCap with the "subtract bias" option selected during generation. In this case, SharpCap (presumably) already measured a corresponding bias frame and subtracted it when saving the flat. In this case, am I correct in assuming that no further bias frame is needed. Can this message be safely ignored, or is a bias frame required by APP to process correctly even in this scenerio?
Ah, yes in that case APP doesn't know about it. It's always advised to use APP itself to calibrate the data.
