Hi,
Tested the rotating shutter at lunchtime. It’s turning at a fair clip. Chop rate is 62.5Hz. This is faster than the LCD rate on the image from the earlier post. I think a shutter with 2 or 3 blades (20.83Hz and 31.25Hz respectively) may be better for more general purpose observing. Need to locate some suitable plastic sheet and get cutting….
cheers,
Bill.
