M33 - Triangulum Galaxy

This is my 4th work. Triangulum galaxy or M33.

I had opportunity to image it for 2 nights under Class 1 Bortle skies. It was in the Altai area, near Kurai (Russia) at 1600m elevation. We were living in camping there for almost 2 weeks, and I hoped for more clear nights, but weather hardly predictable in mountains...

I gathered 80 Luminance frames, 50 Red and Green frames and only 25 Blue frames. each frame 180seconds long.

I tried to gather remaining Blue frames at my backyard at home (class 6 Bortle ), but the difference between single 180seconds frame I got in the Altai and at home is colossal, like night and day... so I decided to use only frames I got in the Altai.

Hopefully I'll have opportunity to image under Bortle 1 skies in the future.

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.
