M101 Finally Happy Enough to Publish

I shot this image in April from a Bortle 3 site and then took some Ha data from my backyard. I could never get it right it just didn't look good. I realize this is because I really didn't get enough data but it was the last night at the dark site and that's all the time there was. Anyway having switched to PI lately I found the PCC process helped me get the colors right and then using the new BlurExterminator Process things started to come together. I've also been doing my noise reduction in PS and I finally bought the NoiseExterminator plug in and that made a big difference. Anyway I'm more than happy with it now.

This was shot with a dual rig: FLT 132 and ASI 6200MM for Luminance and RGB Ha with FLT 91 and ASI 2600 MM.

Luminance 75 mins 9 by 300 s
RGB 25 mins Each 5 by 300 s
Ha 260 mins 26 by 600 s

I've posted a full frame and cropped version, BlurX does make quite a difference especially on the background galaxies.

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.
