And quite do-able, Victor. I used to do it with the DP1 (orig). That explains the f=30mm in the EXIF.

Looks like you achieved about f=500mm with this combo.

I would be interested to know the effective focal length (EFL). That's

(FL of objective/FL of eyepiece) x FL of camera lens.

Not a bad result, if a little noisy. Did you have to up the exposure in SPP? Also, what was the diameter of the telescope objective?
