Tele Vue Visual / Imaging System Adapter (VISA)
The Televue TE-AVI-3200 Visual/Imaging System Adapter allows you to attach a Tunable Top (model TE-ATT-2125) by Televue to a Big Paracorr.
For dual-purpose photo/visual scopes, a TE-AVI-3200 "VISA" adapter (Visual/Imaging System Adapter) accepts the tunable top from the standard Tele Vue 2" Paracorr Type-2. The 2" format is fine visually since secondary mirror size limits maximum exit pupil diameter to around 7mm. The widest true field eyepiece choice with an f/3 is therefore the Tele Vue 21mm Ethos which delivers a 6.1mm exit pupil at f/3.45.
For imaging with DSLR or CCD Cameras, if you have a 35mm format DLSR or CCD camera, the TE-AVI-3200 Visual/Imaging System Adapter ("VISA" Adapter) accepts the Tele Vue Imaging System accessories.
The TE-AVI-3200 Visual/Imaging System Adapter by Televue is precision made from aluminum and black anodized. It is easy to attach to your Paracorr and imaging equipment.
