Hi guys.

Got up in the cold this morning to image Mars again, the jetstream didn't look like it would be too bad. When I first set up, through the eyepiece Mars was a wobbling bowl of jelly so I wasn't confident.. I continued anyway..

I ensured the EQ platform was much better aligned this time, and I was able to take 11 x 180s avi's of Mars.. was nice to just sit back and watch it take frames without having to touch it in-between!

The first few avi's were a write-off as the seeing was still horrible, but after 5-10 minutes it cleared up a bit and I got some useful video. It was still only what I'd rate 5.5/10, but the resulting images are much better than my first attempt on Friday morning. So i'm happy, i've gone forward not backward

The simulation image is from "Mars Previewer II".

The images are a stack of approx 300-500 frames, out of 1800 per video.

Comments welcome.

Hi.

Each video is 180 seconds. That's the commonly held view of how long you can capture Mars for, before its rotation would blur the features. fyi, Jupiter capture length is approx 90 seconds.

So I take multiple videos of 180s each, and process each one independantly to find the one where seeing was the best (and therefore, produces the best image).

Thanks for your comments.

This is with your specific equipment, right? If someone else has more sensitive equipment that retreives better resolution, the time period woulf be shortened I imagine.

Just curious.
