My 90-second movie records the reappearance of Mars from behind the limb of the Full Moon, on December 7, 2022. The movie clips are real-time, not time-lapse or sped up.
On this night the Full Moon occulted Mars, with the planet at opposition and at its brightest and nearly at its largest for its appearance in 2022. The occultation was seen over a wide area of North America and Western Europe. I was in Alberta, Canada where the event took place between 8 pm and 9 pm MST.
This movie documents the reappearance of Mars at “egress” shortly after 9 pm.
Mars appears to be rising from behind the edge of the Moon and the dark Mare Smythii area on the lunar limb. Some dark areas on the tiny disk of Mars are visible, notably Mare Cimmerium. However, the rippling seeing conditions make it hard to see the fine details.
I missed catching a good clip of the inbound disappearance of Mars at ingress an hour earlier. I left switching the camera from stills to video a minute too late, and ingress was half over by the time I started the movie recording. But I was ready for egress!
This was with the Canon R5 in its 8K video recording mode, in Canon Log3 profile, and then color graded in post with Pixelmator Pro and its movie editing functions. I used Pixelmator to create and export the cropped version - it is simply a crop of the full frame sequence. However, with 8K videos there is enough pixels to allow an extensive crop and still have a sharp image. The ISO was 800, the base ISO of the R5 in movie mode.
The camera was on the Astro-Physics 130mm f/6 EDT apochromatic refractor with a 2X Barlow lens to increase the effective focal length to 1560mm at f/12. The Mach1 mount was tracking the Moon at the lunar drive rate. So while it looks as if Mars is moving away from the Moon, it is actually the Moon that was moving away from Mars.
Narration is by me, live as the event unfolded. I was next to the camera and main scope, watching the egress through a smaller refractor set up just for visual use.
