A very amateur effort here, but I thought I might as well post it, warts and all because I don't know when I will get around to doing a better job all around. From  actual framing planning through spacing on the reducer (or whether or not to simply give up on it! ) to guiding (PHD and my venerable AstroPhysics Model 400 don't play well together...) to just simply getting enough integration time on each panel, just about everything has its unmet challenges.  I really will have to have another go at this right from scratch I think, but it is going to wait until I have my CGEM back in working order.  (Manually controlling the mount via platesolving to frame six panels, any of which may involve a meridian flip with subsequent framing was....tedious and trying of my patience and sanity.)  Meanwhile, I will work on what i have to see if I can bring out a bit more (hopefully quite a bit more) detail and contrast from this. I have more data on the lower right side panels to add; the mid right panel is only 38 minutes! The original plan had been to get two hours per panel as a start, but various gremlins got involved...

Some of my outstanding (meaning :  to be resolved !) processing issues:  evening out the backgrounds of the panels (more i-time will help with that), better use of PMM script (actually didn't do it properly to include the lower left panel, hence the fine black line--I knew that would happen, but didn't take the time to do it the right way, as I just wanted to see how it would turn out--I had 5 of 6 panels merged already but didn't have the data for the final panel. As soon as I got it, I just wanted to add it in to complete the picture roughly. A major part of the re-working will be to do the panel registration and adding properly.) Then overall improvement in non-linear processing, recognizing that final quality will be limited by lack of signal. Like most of my images here, a real work-in-progress or more accurately, projects in progress.
