M101 - The Pinwheel Galaxy.

This was taken after a long spell with no clear nights,

Finally got one last night and no moon was up!

Located in the constellation Ursa Major, M101 is a large face-on Spiral Galaxy located 21 Million Light years from Earth. It is almost twice the size of our own galaxy, the Milky Way, being about 170,000 light years across and containing about trillion stars. M101 is asymmetrical - it has been distorted by the tidal forces from other galaxies in its local group.

This image was taken on my William Optics 132mm FLT APO Refractor on a Ioptron CEM60 mount. Camera was a ZWO 294MC Pro. It is the result 42x180 sec subs. Stacked with DeepSky Stacker, and processed with Pixinsight and Photoshop.

This was a quick and dirty edit to see what I ended up with - I will be revisiting this....

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.
