I haven't imaged many galaxies, this is a first time for M104.
I had about 3 hours, and got these subs:
10X300s R
10X300s G
10X300s B
ASI2600MM
GSO RC8-CF with J.Bunn modified back plate
Pixinsight + PS
Nice pic Mark, I did a little bit of pixel-peeping and quite impressed with the roundness of stars at the corners. Your collimation is exemplary. Hope my similar JB-adaptored CF-RC8 will also be capable of that level of fidelity. Doesn't seem to warrant any investment in a dedicated RC flattener.
Unfortunately, constant rain, cloudy nights and cloggy Darling Downs black soil are still inhibiting my star testing efforts. Almost two months!
In a fit of boredom, decided to go all-out and buy a ZWO OAG on IIS, plus IMX462 guide camera to help the RC8 + IMX533 pro do its galaxy work at 1630mm fl. Sort of getting rid of all the potential excuses for poor quality pictures...
Seems like your JB adaptor was a worthwhile investment, hopefully with a second opinion from me one day soon.
