Triangulum Galaxy in LHaRGB

This project started as me looking for something to enter in the Q4 Raleigh Astronomy Club Imaging Challenge. This quarter's challenge is to take one exposure picture of anything. I decided to try Triangulum Galaxy.

I was thinking it was a bit dim but it really isn't too bad. I took a series of exposures from 15s to 900s to see what I could get. I ended up messing up my sequence and taking 4x more data than expected. So I did a bit more of a comparison for the challenge on how different exposures compare when processed. And since I had the data, I added that luminance to a short set of color data I managed to get before the clouds rolled in. It was much less data than I had intended but the result is quite nice! I added more data, including H-alpha.

Triangulum Galaxy is a face-on spiral galaxy 2.73 million light years from Earth and appears in the Triangulum constellation. It is in our local group of galaxies and is the 3rd largest of the group, behind only Andromeda Galaxy and the Milky Way Galaxy. If you're in really good viewing conditions and have no light pollution it is possible to see Triangulum Galaxy with your naked eye! This makes it the object farthest from Earth that can be viewed without magnification.

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.
