M101 (pre-supernova) on SVX102T

Capture
This is one of the best and new photos I've gotten out of my new Stellervue SVX102T Telescope. I spent 15 hours on this total so far over 4 nights. This was captured with an ZWO AM5, and ZWO ASI 2600MC, so no filters.

Post Processing
I was having trouble with getting colors right recently, but it appears its because DBE has been messing up the colors preventing the color calibration from working right. So the solution is to do color calibration before DBE or stretching. I tried HDR Multiscale on this, but got rid of the core glow too much, so i did a light mask with a range selection to balance out and reveal the core a bit instead. Didn't do a whole lot to the original image as it came out great out of the stack. Nice to see what you get with good data.

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.
