Hello,
I intend to capture the Venus transit with a 4" f/10 refractor at 1.14arc sec'per pixel. What is the maximum AVI length I can take before I would see a "smeare" and Venus disk would become elonged? I need to know Venus angullar speed, if you can even give me this number it would be great.
Kind regards.
