Televue Tunable Top W/1.25" Adapter
The Televue model TE-ATT-2125 2" Tunable Top with 1.25" Adapter is the tunable top from the standard Tele Vue 2" Paracorr Type-2. It lets the user position all eyepieces for optimum coma correction. For use on the BIG Paracorr, the "VISA" (Visual/Imaging System Adapter, sold separately) is required. A 3" Tunable Top is not required since secondary mirror size limits maximum exit pupil diameter to around 7mm. Therefore, the widest true field eyepiece choice with an f/3 is the Tele Vue 21mm Ethos eyepiece, which delivers a 6.1mm exit pupil at f/3.45.
To use the TE-ATT-2125 2" Tunable Top by Televue, just remove the stop flange from the Big Paracorr, attach the VISA adapter (TE-AVI-3200) adapter to the top of the Big Paracorr Type 2 and then screw the Tunable Top on top of this adapter. However, the Televue TE-ATT-2125 2" Tunable Top will attach directly to a 2" Paracorr. Then adjust the sliding lever on the side of the Tunable Top barrel to position your eyepiece according to the chart which is provided by Televue, to obtain the optimum coma correction. The included 1.25" Adapter can be inserted into the top of the TE-ATT-2125 if needed for your task.
For imaging with a DSLR or a CCD Camera, if you have a 35mm format DLSR or CCD camera, the "VISA" adapter accepts Tele Vue Imaging System accessories.
