Title: Binned Bias Frame? for Binned Flat Frame calibration
Post by: cdavid on 2014 September 28 06:39:16

Hi, wondering if someone can clear something up for me.  I have previously created some superbias frames for my ST-7 camera.  I was imaging LRGB and obtained 2x2 binned RGB light frames and took 2x2 binned Flats for each filter.  I just realized my Super Bias Frame which I wish to calibrate the Flats with was taken at 1x1 binning mode.

Is this an issue?  Should I have 2x2 binned Bias frame to calibrate my Flats?

Thanks
Carlos

you should get bin 2 bias frames, as the hardware binning produces a bias file that in theory should be different than what you'd get from software binning.
