Description

Introducing Tunable Top for the BIG Paracorr Type-2.

The 2" Tunable Top with 11ƒ_4" 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 eyepiece choice 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.

Installation.

Attach the Tunable Top by unscrewing the Stop Flange from the top of the BIG Paracorr Type-2 and replacing it with the "_VISA" adapter. Then screw on the Tunable Top. Tighten the Tunable Top snuggly.

Use.

For 2" Eyepieces:

  1. Make sure eyepiece lock screws (A) are loosened
  2. Remove 11ƒ_4" adapter.
  3. Slip 2" eyepiece into the Paracorr
  4. Tighten eyepiece lock screws (A)
  5. To adjust for eyepiece position:
    a. Slightly loosen the height adjust- ment lock knob (B) that clamps on the slot.
    b. Push the screw (B) to adjust the height of the eyepiece, following the guidelines in the eyepiece posi- tion chart below.
    c. Tighten the "_

For 11ƒ_4" Eyepieces:

  1. ‹¨¬Slip the 2" to 11ƒ_4" reducing adapter into the Tunable Top and A tighten lock screws (A).
  2. Place the eyepiece in the adapter and tighten the lock screw (C)
  3. Follow the adjustment procedures outlined above in step 4.

Note: Focus the telescope after B properly setting the eyepiece position. Do not accidentally use the tuning feature for focussing.

The easiest method for finding optimal correction for other brand eyepieces is to first establish the focus position with a Tele Vue eyepiece at its known Paracorr setting. Then insert your other eyepiece and use the tunable top until focus has been reached. Note the mark on the Paracorr body for the setting. Use your telescope focuser to tweak the focus if necessary.

CAUTION: Do not insert any accessory (Barlows, collimators, etc.) with a barrel length more than 13ƒ_4" into the Paracorr, to avoid contact with the Paracorr lens.
