Re: New Image: Sirius and Pup
Measured the image and at 0.19 "/pixel the separation works out to 11.3", about right, but no cal on my setup, and with a moving mirror focuser, like all SCTs, focal length hence plate scale varies, so just lucky to be near design spec.
Notes on exposure for others, my guess is that 30ms to 100ms should work with any sensitive modern
Thanks again,
Steve
