Making do with zoom lens.

#1

Post by Jennifer Christine »


I wanted to use a smaller guidescope, but couldn't justify buying a whole new one.
I seldom use my 70 to 300 kit lens so devised a back cover by cutting a hole and glueing a nose piece on and screwing a webcam on the back. Some small elastic band stopped the focus ring and zoom ring slipping.

Woorked great.
Scopes, 100x900, 102x500, 150x 1000, 200x2000, 200x 1260. 80x400.
Canon lenses 100 to 400 L series, 18 to 135 usm.
Mount's, 2x alt az, 2 x eq (adventurer an neq6pro.)
70dw cam. Ssag guider. Observatory and pier setup.
Binoculars Saxon 20x80.
FRIED wallet.

I'm doing the same thing using store-bought adapters and spacers using my ASI120MC. I want to use mine as a polar scope.

Cheers,
