M31, M32 and M110. I shot from my driveway under Bortle class 7 skies. 25 minutes total exposure time. 33 x 45 second exposures at ISO 800 using a Nikon D5100, Meade Series 6000 Astrograph 70mm APO Quad refractor and Celestron Advanced VX mount. This shot was unguided. Only the mount was used to track the object. No filters. While I am not new to astronomy, I am very new to this type of astrophotography processing involving stacking and Photoshop workflow. This is only the second time I have actually followed the process to its end. So while to most of you will probably look at this image and can point to a number of mistakes and issues, I on the other hand am quite happy with how it turned out with only 25 minutes of data, the sky I'm dealing with and my limited experience. Still I want to get better and encourage your feedback. Thanks for looking.

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.
