Leo Triplet (M65, M66, NGC 3628)

One of the most photogenic galaxy groups in the Northern sky, the Leo Triplet (M65, M66 and NGC 3628). The LRHaGB exposures for this image were taken in April 2024 with my mobile setup, the 250 mm f/4 Lacerta PhotoNewton and ZWO ASI2600MM Pro and ASI294MM Pro cameras riding on top of the Orion HDX-110 EQ-G and SkyWatcher CQ-350 mounts. R channel is a combination of the R and H-alpha data. The original exposures were factor x2 drizzle integrated to increase image resolution. Star reduction was done using RC BlurXTerminator, while the extended objects were sharpened using RL deconvolution and Multiscale Transform.

Exposure Information:
L: 31x300s (Gain 0, Bin 1x1) (ASI2600MM Pro)
L: 6x300s (Gain 0, Bin 1x1) (ASI294MM Pro)
L: 123x90s (Gain 100, Bin 1x1) (ASI2600MM Pro)
R: 42x180s (Gain 100, Bin 1x1) (ASI2600MM Pro)
G: 37x180s (Gain 100, Bin 1x1) (ASI2600MM Pro)
B: 36x180s (Gain 100, Bin 1x1) (ASI2600MM Pro)
Ha: 26x300 (Gain 100, Bin 1x1) (ASI2600MM Pro)
Total Exposure: 14.1 hours

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.
