M74

I haven't had any clear nights since 12/29. I finally got a really cold clear winter night but a
front was coming through and it was really windy with bad seeing. I decided to go with it
and image anyway I'll probably revisit this sometime in the future.

M74 is a beautiful face-on spiral galaxy located in the constellation of Pisces. It's an archetypal
example of a grand design spiral that was discovered by Pierre Méchain sometime during September
1780. Méchain reported his discovery to Charles Messier, who subsequently determined its position
and then catalogued it on October 18, 1780. This galaxy is located 32.5 million light-years away
and has a diameter of about 95,000 light-years, which is similar to that of the Milky Way. It has an
apparent size of 10.5 x 9.5 arc minutes . In 2002 and 2003, supernovae were discovered in M74.

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.
