If this is a "rawish image" I can't wait to see the final image! Looking great already. Thanks for sharing, Jim.
Thanks Henry. By rawish I mean I was really just testing the camera hoping that I would collect some decent data. The calibration files are not good and the darks don't match the exposure time, but I processed the batch just to see what "come out".
Looking like the mod will be a keeper!
I am shooting more light frames of M33 now. Another poor seeing (windy) evening, but clear enough and I will take what I can get. I will worry about the darks another day.
Thanks for your comments!

Pretty image Jim. The mod really brought out the red "knots" in the arms. Congratulations on getting your camera modified. You won't regret it.
You may want to look into using some filter to limit the red response to wavelenghts beyond the Ha wavelength. This will help prevent "blurring" caused by the extended red beyond the Ha not focussing properly. I successfully used an IDAS LPS-D1 filter for this purpose for a few years. It also helped with my Light Pollution.
I am having fun Steve and thanks for your nice words.
Collecting more data now. I have already collected 18 images at 120 seconds (matching the dataset from last night). I really like Standard Time! Shooting for a total of four hours (that will be a new record for me).
The filter sounds great and I do really need to limit the reds beyond Ha
. I have another project going on right now. My son and I are building a new desktop to process images with. New AMD Ryzen 8 core cpu with a big graphics card. Got the cpu, graphics card, and power supply in today. The main board, case, and ram will be in before the end of the week. Perfect timing since my son leaves for Navy OCS next week.

Looks great Jim!
Thanks a bunch Bigz! Having a blast. 41 degrees F outside (cool for Mississippi) with Jack hanging with me. Of course, I am watching the action right now from the inside pc getting ready to get an ice cream cone.
