M31 – The Andromeda Galaxy

We had our first cold front pass through for the autumn which gave me my first night out for the season. The Winter DSOs are not up yet so I took a shot in the dark to find M31. After several adjustments, since I am not using a Go-To mount, I found my target. The temperature was a cool 48 F (3.3 C) and the seeing was average (3/5).

On advice from Niall MacNeill I change my ISO from 800 to 1600 and the results were better in my opinion. There are lots of great images of M31 lately and even though mine does not compare I am happy for my first night out. Since I haven’t been out for months I made the rookie mistake and did not clean the lens properly so please disregarded the smug.

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.
