Hi Tom… a quick question.
It is probably written somewhere, but I do not recall seeing it.
What camera do you use to record these videos…
And if you don’t mind, what software to process…
Thanks in advance.

Really nice work Tom!
Is your Moon shot a single CCD exposure or did you use a high speed CMOS
camera and Registax or similar with hundreds of frames or similar to produce
The moon image used the best 500 of 1000 frames. Recording that number of
frames is probably overkill for 540mm focal length. The image is full-frame
(1920x1080 pixels), so video files get huge in a hurry.
For Mercury and Venus, the focal length is 2700mm, so the seeing moves the
image all over the place. In that case, I used the best 500 of 4000 frames.
Since the angular size of those planets is so small, I use a very small
sub-frame (planetary imagers call this an ROI), which keeps the video file
