My third go at M101 Pinwheel galaxy

At just short of 19 hours I think this is my longest integration so far

Ha 840 x 300s = 7 hrs (during full moon period)
Lume 840 x 30 = 7 hrs
Red 230 x 30 = 1.92 hrs
Green 178 x 30 = 1.48 hrs
189 x 30 = 1.58 hrs
= 18.98 hrs

Taken over 5 nights in March 22

All three goes have been with my Orion first one using my DSLR and last two with my ZWO ASI 1600 MM etc , first two were less than 2 hrs each

This is the best one but ...

Stars are terrible - collimation was off maybe ? Bad coma even though coma corrector in place. Really bad gradients due to light pollution so processing was a real pain .

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.
