M33 - Triangulum Galaxy

Finally got around to digging out the old GSO-generic 8"f/4 newt to see what it can do. A couple years ago I upgrade the focuser and got a Sesto Senso focus motor along with a Baader Coma Corrector. After fiddling with the collimation I loaded up the mount and attach the CCD/EFW to see the situation. Overall this scope has promise, just need to tweak the spacing (i think a 2-3mm closer) and deal with what appears to be some tilt with the lower right corner stars being non-that-round!

The biggest takeaway(victory!) with this image is figuring out my gradient issue in the lower right that has plagued me for over a year. Long story short, my Lum flats were too short even at 3s for this ATIK Camera. I adjusted my flat panel setup and got the exposure to 10s and boom, the issue went away for or less and one quick DBE pass and the Lum (and RGB) channels looked great.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
