Greetings from Florida.  The skies have been clear so I powered up the observatory to grab some data.  I have been noticing a red fringe on my stars and upon closer inspection the PSF of the color channels are not uniform.  I have read that color channels need not be critically sharp since L channel does that.  I would tend to disagree.  Normally I don't inspect too closely the color channel subs but I guess I will have to in the future.  I know for L channel I reject any sub that has FWHM greater than 2.4.   Details here https://www.astrobin.com/67vnun/
