M109 and friends

Between skiing vacations and bad weather it has been over 3 weeks since I had my scopes out, almost forgot how to set up and PA. Took me over an hour, when normally it only takes me minutes. Anyway this is just over 6 hours of data with 2 different scopes and camera's. The first session was at the beginning of Feb with my ES 127mm & ASI 2600MM and the second session was last night with my SW 190mm Mak/Newt and ASI 2600MC. And on a side note I think I finally have my Collimation pretty darn close as my stars look pretty round, even on the edges.

M109 was discovered by Pierre Mechain in 1781 and was listed as Messier's 109th target in 1783. M109 is around 84 million light years away. It is the brightest galaxy in the Ursa Major Cluster and is surrounded by three satellite galaxies (UGA 6923, 6940 & 6969).

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.
