Sometimes you are lucky as in this case. I woke up during a cloudy morning to discover a gap which lasted just long enough to open the roof, collimate the scope, start the PC and capture these just as the clouds returned. lol
That's great for a quick look! And really interesting to see the cloud changes over the past week since I imaged the same face on Sunday, that long high cloud over Syrtis Major is new. What next on Mars?
