The Faint Arms of M101

Messier 101 more commonly known as the Pinwheel galaxy is a face on spiral found 21 million light years away in the northern constellation of Ursa Major. With a diameter of 170,000 light years M101 is close to twice the size of our galaxy the Milky Way and contains more than double the amount of stars. One of the main features of this galaxy is its dislodged arm, this asymmetrical feature is likely due to the tidal forces from interactions with its companion galaxies of which there are five prominent members. M101 is also know for its high population of enormous star forming regions which would appear pink in a color image.

Just a luminance image! Been holding on to this data for over a month now hoping i would get the opportunity to gather more. The plan was to try and gather around 40 hours exposure and go really deep on this. But with the mount being out of action i have not been able to and now the galaxy is in a less than ideal position for me, so this is a mere 4.5 hours and second light for my CCD.

To be continued next year...

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.
