Location: Triangulum Constellation
Distance: ± 3.2 million lightyears
Diameter: ~60,000 lightyears
Stars: ± 40 billion

This target was too large to fit in one frame with my telescope/camera combination so - to capture the whole thing I had to image each half of the galaxy independently & merge it all together in the end - this image was a serious learning curve & love/hate thing throughout. I am however happy with this as a final result, & happy to put this data to rest for a while!

Total imaging time (on target): 39.756 hours
Total integration time (best 80%): 33.13 hours
Integration (L+Ha, R+Ha, G, B) as follows:

86 x 420s Luminance - 1x1 bin (43 per panel)
54 x 840s H-Alpha - 2x2 bin (27 per panel)
40 x 315s Red - 2x2 bin (20 per panel)
40 x 315s Green - 2x2 bin (20 per panel)
40 x 315s Blue - 2x2 bin (20 per panel)
- 14 flats per night & filter,
21 darks per exposure type,
28 bias per binning level.

Data captured with sensor placed at -15°C, at scales of 0.84”/pixel, 1.68”/pixel & over 7 nights between October 5th 2021 & November 7th 2021.

Main equipment used:
William Optics FLT 132
Avalon Linear FR
Atik One 9.0 + Chroma filters

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.
