Planets

Mars is approaching opposition next month (October 13th) and is currently as close to Earth as it will be for a long time, in addition it rises high in the sky overnight, out of the haze and atmospheric gunk that Jupiter and Saturn are in now. Now is the time to photograph the planet. I tried it last night with the C8 and a 2.5 Televue Powermate. With this combination I’m getting about 5000mm focal length, but good atmospheric “seeing” is essential. Last night was just OK, I’m hoping for at least one good night with excellent seeing. It may be possible to see some volcanoes on the surface, like Olympus Mons, with excellent seeing. I don’t know if I can pick up on things like that with my equipment but I will keep trying.

This is the best I could get. It is much better than my previous attempts. This is a stack of over 2000 video frames selected by software from over 8000 frames, then stacked. The south polar cap is on the upper left and one can see north polar ice clouds at lower right. The largest dark area in the center is Mare Erythaeum. At this link is a good map that labels the features: https://www.wa2guf.org/mars-opposition-of-2020-2021/
Jupiter didn’t turn out so well but one can see the moon Io peeking out from behind the giant planet.
