Description

My take on the Owl Nebula. Yes BiColor but the reverse of the usual. Ha = Blue and Oiii = Red.

I tried with RGB stars instead of the NB but thought this (with NB stars) was more appealing.

Still dialing in cooled cmos imaging, with the seaming endless discussions (some of which I am flogging on, in the hopes of a consensuses and even an auto exposure tool) of exposure, to bin or not to bin (cmos vs. ccd, and at an my image scale) , etc.
