Here's a nice Borg 76 mm refractor OTA in the rare and beautiful Borg
silver metallic finish. I replaced the non-matching white dewcap with
a custom polished aluminum one. It's very compact, measuring only
15" long and can it's modular design allows it to be easily disassembled
into an even smaller size. Everything is in excellent condition.
Note: this is not the ED version, but it has less color than the common
short tube scopes.
Here's what you get:
Borg 76 mm achromatic OTA with sliding dewcap and drawtube
Borg helical focuser (very smooth)
Long extension tube (about 2.25" long)
Short extension tube (about 0.75" long)
Adapter ring that provides T-thread and 36.4mm thread
2" visual back (usually an accessory)
1.25" visual back (usually an accessory)
Baader Solar filter in aluminum cell with plastic case
You need to provide your own 1.25" or 2" star diagonal and eyepieces
(parfocal are recommended). You also need a photo tripod or mount.
This OTA has a 1/4-20 mounting block. For photography just supply a
T-ring for your camera.
