M 33, the Triangulum Galaxy

The Triangulum Galaxy is a member of our local group of galaxies and is the third largest, behind the Milky Way and Andromeda galaxies. At its estimated distance of 2.73 million light-years, it is one of the most distant objects that can be seen with the naked eye. It is a somewhat difficult object to detect visually, despite its apparent magnitude of 5.72, because of its low surface brightness. I have an easier time seeing it in binoculars than a telescope, usually.

This image was taken at the Nightfall star party in Borrego Springs, California. At Bortle 3+, the site is not super dark but the sky is at least two magnitudes darker than what I have at home.

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.
