New images of R CrB from BSM_TX are all good except for B. The B exposures of 6 seconds saturate the target. The max ADU in the measuring aperture is 62K, and the linearity limit is set at 55K.
In order to keep the SNR's of the comps up, I'd recommend first trying B exposures of 5 seconds. If we eventually have to go down to 4 seconds I'd recommend increasing the number of B exposures.
Tracking, focus, and image quality are excellent.

How do I access my currently active observing proposals in order to make comments?
