The Triangulum Galaxy - M33

Boy I'm glad to be able to produce an image that I've shot before, with an entirely new imaging setup and a ton of new information and better technique. This object is the Triangulum Galaxy, the smallest galaxy in our local group, along with the Milky Way and Andromeda. This is a traditional spiral galaxy lying a distance of about 2.7 million light years and spanning a size of about 60,000 light years (about 60% the size of our Milky Way galaxy). You can view this object pretty easily with binoculars or a small telescope in the constellation Triangulum from about November to February.

This object was discovered in the 17th century by a few different people, the first of which was probably Giovanni Battista Hodierna but later it was found by Charles Messier independently and added to his list as the 33rd item, hence the designation, M33.

This galaxy has a perfect orientation to us, showing its large spiral arms, and it contains many bright red HA regions that really make this galaxy stand out when compared to other bright galaxies in the night sky.

I'm super glad to be able to share this image with you guys today, this object is one of the main reasons I wanted a telescope with a longer focal length, and because this setup is about perfect for this object, I went deep with just over 18 hours of data. I hope you guys enjoy it, it took almost 6 months to produce this image due to weather, and a full day and a half of processing due to my obsessiveness and a total of 543 sub frames.

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.
