I will get it though. Your focal length was 6250mm with the powermate? Yes?

Hi Paul

Hmm, I wouldn’t like to attempt something like this with unfamiliar equipment or software; it’s hard enough when you know your stuff. Sorry to hear it didn’t work out – this time.

The C9.25 has a native focal length of 2350mm, so using a x2.5 PowerMate should give 5875mm. My configuration was:

OTA → Motofocus → CCD camera. I’m not too sure if the additional 3 or 4 inches of the motofocus changes the formula? Robert T seemed to experience this with his filter wheel?

Cheers

Dennis

Np, the ball park figures are fine. I was trying way over that at around 7.5 m +.

I'll definately get there.
