Many thanks for your comments, guys.


Milton, the seeing looks very good through the clouds. I find this to be the case with light cloud cover, though I'm not sure if it is real, of it is the obscuring of the data that makes it appear so.


How do you go about cropping the dimensions of the movie? I've wanted to do that recently but couldn't figure out how.


Here is a mosaic of two very different exposures showing a sliver of atmosphere during a similar moment of the transit from California. My seeing was much worse than yours at this point:

Hi Alan and others;

Super images. Thanks to all for sharing them.

I cropped a small 320x240 area around Venus yesterday from my big 1384x1036 movies, just to show the sort of conditions I was dealing with during VT. It's a short 30 second clip at 22 fps and was taken at 16:19:24 local time.

Astro IIDC was running in Auto Exposure, which is why the brightness of the movie remains pretty constant - despite the clouds.

At the end, I must have had one of those 80+ kmph wind gusts which shakes the mount around.

TTYL..
