Block knob (B).

Introducing Tunable Top for the BIG Paracorr Type-2
The 2” Tunable Top with 1¼” Adapter (model #ATT-2125) is the tunable
top from the standard Tele Vue 2” Paracorr Type-2. It permits positioning
all eyepieces for optimum coma correction. For use on the BIG Paracorr
Type-2, the “VISA” (Visual / Imaging System Adapter), 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 eyepiecechoice with an f/3 (f/3.45 when used with Paracorr) is Tele Vue’s own
21mm Ethos, which delivers a 6.1mm exit pupil at f/3.45.

C

For 1¼” Eyepieces1) Slip the 2” to 1¼” reducing
Aadapter into the Tunable Top andtighten lock screws (A).
C2) Place the eyepiece in the adapter
and tighten the lock screw (C)A3) Follow the adjustment procedures outlined above in step 4.
Note: Focus the telescope after B
properly setting the eyepiece position. Do not accidentally use thetuning feature for focussing.
The easiest method for finding optimal correction for other brandeyepieces is to first establish the focus position with a Tele Vue eyepieceat its known Paracorr setting. Then insert your other eyepiece and use thetunable top until focus has been reached. Note the mark on the Paracorr
body for the setting. Use your telescope focuser to tweak the focus ifnecessary.

Installation
Attach the Tunable Top by unscrewing
the Stop Flange from the top of theBIG Paracorr Type-2 and replacing
it with the “VISA” adapter. Thenscrew on the Tunable Top. Tighten
the Tunable Top snuggly.
