Mounted the D850 DSLR at prime focus. Took this image (1/250sec, ISO 400, White Balance Auto).

Removed the camera and did some lunar observing, 203X. There were many nice sights.

Viewed Jupiter again, 203X. All four Galilean Moons were now visible in the darker sky.

Viewed the Trapezium stars in M42 (Orion Nebula), 203X. Then removed the 2X Powermate and viewed M42, 102X. Some nebulosity was visible in the moonlit sky.

I stepped outside of the observatory to put the Dome back on. The constellation of Cassiopeia was looking down on Cassiopeia Observatory. So I just had to take a photograph. This handheld iPhone 15 Pro Max was taken with the Camera app (Night Mode, 3 seconds, 1X lens) and shows Cassiopeia at the top. Tilt your head to the left and you'll see the "M" shape (which, of course, stands for Mike).
