Who said you need 3 channels for an RGB image!?

It is strange but I have beeter luck with bicolor broadband images than I do with bicolor naerowband images.  In fact, what usually happens is my bicolor btraodband image ends up better than a full RGB version for some reason.  After a coupleof decent nights, I decided to see what I would end up with using just red and green data for NGC 1977.  The stars are not colored very well, and this is an HDR composition using 120 sec and 10 sec subs to restore clipped stellar cores, so I definitely want to collect blue data (and luminance), so the stars come out nicely colored.  Also, I simply must replace the ASI 1600 with the 2600.  The star microlensing artifacts are just not acceptabl

TOA 130 with .99x flattener and ASI 1600.  139 120.sec and 90 10 sec red, and 100 120 sec and 90 10sec green, bin 2x2. About 8.5 hours.
