A definite improvement and a testimony of your efforts - well done Scott
This B/W photograph is very nice, but I will also look forward to a colour version.
P.S. If I may...I think your last hurdle to overcome is flex between the main camera and a guide camera. I can see a few nice trails of hot pixels indicating how much the system has flexed...it took me many months of experimenting with my equipment until I discovered flex was due to a locking ring (I won't mention the brand...) between the filter wheel and a camera.
