M84 & M86 in Virgo 24th March 2020 @ 00:50 UT
The two giant elliptical galaxies of M84 and M86 dominate the field but they are joined by many other fainter galaxies. I soaked up light for 47 minutes (my Hubble deep field)!
Image: 15 seconds x 190 frames (2850 seconds total), gain 6584, bin 2x2, Raw 14, black level 99, camera temperature 10.2 deg C, 1 dark. Stacked in SharpCap Pro 3.2.6248.0. The image was stacked and adjusted in SharpCap. The image was scaled down in GIMP.
This is the longest I have left the camera pointing at the same patch of sky. Even though M84 and M86 immediately appeared as fluffy blobs I really wanted to see the surrounding galaxies. As the frames built up and I played with the adjustment the smaller galaxies formed into spirals with structure!
In the image below I have marked and named several galaxies. There are many more that could be extracted from the image.
Equipment: Celestron CPC-800 at F5.9, Alt-Az mount, Altair Astro Hypercam 294C Pro Cooled (fan), Celestron Focuser, CPWI controlled remotely via Microsoft RDP and ASCOM.

Charles Messier came across M84 and M86 on March 18th 1781.
