Re: [APML]: Genesis SDF negative projection setup

Jim,

Tele-Vue makes a 3" extension tube for use with the T-V Big Barlow at prime
focus. The extension tube goes into the focusing tube, followed by the Big
Barlow, then the prime focus camera adapter. The Tele Vue part number for
the 3" extension tube is X3T-0009. I just purchased for one for $39.95.
Haven't had a chance to use it yet though. Hope this info helps out.

Garth
