Triangulum Galaxy (Messier 33) Ha+LRGB Widefield

Messier 33 Ha+LRGB

Captured with a monochrome camera, at a focal length of 380mm, this wide field image of the Triangulum galaxy has a total integration time of 16 hours. Five of the 16 hours were captured through an Ha filter and that data was added to the red channel to highlight the regions with potential star formation activities.

The largest documented stellar nursery is located in the lower central portion of the image and is designated as NGC604. For size comparisons, NGC604 is about ten times the size of the Orion nebula (Messier 42), one of the closest stellar nurseries to earth. This makes the NGC 604 region of the Triangulum galaxy one of the largest stellar nurseries to ever be studied.

At 2.8 million light years away, Messier 33 is the third largest and the most distant galaxy in our local group of galaxies. Although it is smaller in size compared to the Milky Way and Andromeda galaxies, its overall size and brightness permit it to be seen with the naked eye, when observing in dark skies.

I'm new to shooting and processing galaxies in monochrome and I always want to produce a better image. Constructive feedback is welcome.

Thanks for viewing!

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.
