Messier 101 - Pinwheel Galaxy

Well, I am now officially running out of subs after the nice weather period we had here. This is the last one of my images taken over the last two weeks.

Here my attempt on M101. It is featured in AstroPixelProcessors Tutorial section: [Sticky] Star Color Calibration 1.58 (I couldn't get the star colors right in the beginning)

So great to see real world physics embedded in Astrophotography ... I love the star colors now that I found out how to correctly use the color calibration tool.

Second attempt this year on the Pinwheel. Now with some proper integration time! Love SGPro for letting me sleep

So many galaxies to see on this one, really great to see what some 16ish hours can do on a little scope.

Also another one of my series "been there before last year": M101 by Frank Schmitz

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.
