Details:
During the current opposition Martian satellites is rather easy target. At least I captured them much easier than in 2016. The animation demonstrates rotation of Phobos and Deimos around the Red Planet. The seeing was rather bad (3-4/10), but didn't spoil the result too much. I used Celestron C-11 (prime focus, 2800 mm), ASI 290MM in bin 2x2 mode and 10 fps frame rate with IR/UV block filter. Stacked 900 best frames of 1800, six movies were recorded in approx. 7 min intervals. Between these movies, Mars was captured with R, G, B filters to get non-overexposed color image, which was added afterwards. The animation covers time period 21:21 - 21:53 UT, 23 July 2018.
Some background stars are also visible, obviously Mars also makes its way around the Sun.
