Olympus Mons much clearer now and Arcadia next to it. Just a 10 minute gap in the clouds but rasonably steady.

Mars 2020 updates

15 October 2020|Mars, News|

Lots of Mars images clogging up my newsfeed so one image “to rule them all…” to be updated through the apparition.

Just going to keep updating this throughout the apparition rather than keep putting new images up. Also marked out a few of the more interesting and well known features. I was delighted when I managed to find Olympus Mons although it seems to be brighter this year than in previous apparitions.

Seeing variations make a big difference to detail that can be seen as does my ability to process them. I put the first one in as that’s where I started this year and similar to the best I’d done with Mars before this year. I clearly had to up my game.

Medium good seeing again. Trying out new techniques, less Gamma on recording, lighter touch but there’s more noise now. Still not happy with the results but I suspect I never will be.

Mars images are now being sent to the Mars section of the BAA.

Decent seeing even when low down but then went to boiling as it got higher. The “peninsula” off the Mare Cimmerium are visible. Sinus Gomer?

Not the sort of instrument to normally use for planets but surprisingly OK – mostly because of good seeing – at least for here.
