The Leo Triplet

Revision title: Revised image using PI

Finally got a full clear night. I started this image 2 nights ago, but Mother Nature was messing with me, I had clear skies for about 2 hours and then overcast. However, last night it was clear all night. This is the first full image with my new 190mm Mak Newt since getting it collimated. I am pretty happy with how this turned out as the detail and color both look pretty good to me. Let me know if you agree, LOL!

Leo's Triplet includes galaxies in Messier's catalog (M65 & 66) and NGC 3628 (the faintest of the group which is why it escaped Messier's small scope. All 3 galaxies are around 35 million light years away. NGC 3628 is around 300,000 light years long, M65 has a diameter of 80,000 light years and M66 has a diameter of 75,000 light years. Although close to the other 2 galaxies, M65 looks like a normal Sa type galaxy. M66 is classified as type Sb with deformed spiral arms probably do to close encounters with its neighbors. NGC 3628 also shows some deformity due to gravitational forces from the other galaxies.

Title: Revised image using PI

Description: I captured this image almost 2 year ago, before I was using PI and was just curious if I could improve on this image for my Astronomy picture book. When I first loaded this, I thought it was one of my better images and it was not a bad image. I was able to pull out some more detail using PI, but my background is not as clean.

Also, I left the wider FOV as I noticed several other little galaxies as I was reprocessing this image.

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.
