M31, backyard

Around 10 hours of exposure time, so far, across five nights late August - September, from my backyard in the city of Graham, NC.

Andromeda Galaxy is a good, large, bright astrophotography subject with a lot of dynamic range from its bright core to its star clusters and wispy edges. I'm using a 350mm focal length scope and a full frame sensor on a mirrorless Canon Ra. Started with unguided exposures the first few nights, but went to autoguiding for more consistent results, longer exposures with tighter stars.

I've been using this familiar target to work on my setup with this scope and a new mount, an iOptron CEM25-EC. After multiple nights trying different things without guiding and talking to other astrophotographers, I decided the mount would need some autoguider correction now and then.

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.
