04/07/2024- The Leo Triplet – M65, M66, and NGC 3628

Nice clear night. A little cool, but still a nice clear Moonless night. I was setting up more to make sure everything was ready for the Solar Eclipse, but decided to have a quick go and capturing some light since it was such a nice night.
I uncovered the scope late in the afternoon. After dark I ran the Ekos Focus routine and then the Ekos Polar Alignment routine.

The Leo Triplet is a group of galaxies which includes Messier 65, Messier 66, and NGC 3628. The Leo Triplet is about 35 million light years away and is located in the constellation of Leo.

This is a stack of 18 x 300 second exposures at 121 gain, 30 offset, and bin 2×2. The image was stacked, cropped, and processed using Sirilic and Siril. Had a lot of issues with airplanes and satellites early in the night. The first five frames were full of them, I counted 4 in one frame. The satellites and airplanes either stacked out or got cropped out.
The Leo Triplet M65, M66, NGC 3628. 18 x 300 seconds stacked and processed with Siril.
Ended up with a nice image for only 1 1/2 hours of exposures and about 10 minutes fiddling with it in Siril. Messier 65 (M65) is to the top left, Messier (M66) is to the bottom left, and NGC 3628 (some times called the Hamburger Galaxy) is to the right.

Greg set up his gear as well and got a really nice live stack of the Whirlpool Galaxy.

Nice night to look up. Packed up and covered the scope just after 10:30 PM. Ready to look towards the Sun…
