For the first time since I started with Astrophotography I have reached 20 hours of integration in a project.

All the shots were taken from my balcony with the object between 30 and 55 degrees (AZ) and it took me 7 night to complete all the integration.

The object in question is The Pinwheel Galaxy (M101), a small galaxy 19 million light years away and not particularly large in relation to my equipment.

Not only that, although it is a galaxy it is not even particularly bright because it is "cataloged" with an apparent magnitude of 8.3 when, for example, the Andromeda Galaxy is 3.4 (the smaller the number the brighter the object).

To complicate things, the fact that I used my APO at full focal length without reducer and therefore with a focal ratio equal to F7 which certainly did not help in this but in any case I am satisfied with the final result.

In the lower right, in addition to M101, it is possible to see a small peculiar dwarf galaxy, NGC5474, even more "faint" than M101 for which it was very interesting to observe how inside the small details "came out" with the integration.

The acquisition was done for the first 14 hours with 600-second poses while the remaining 6 hours I covered them with 900-second poses to see if I could recover even more detail.

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.
