BORG (Japanese) 76ED APO (apochromatic) telescope.
$1,000.00
Sold
These don't come up for sale often.
ED glass optical quality.
Native focal ratio is f6.6 (502mm focal length). Reduces to f6 with the included 0.85x BORG Focal Reducer (PN 7887).
Note: This reducer is designed also as a field flattener for large CCDs. I used it with the STL11K.
Package includes:
SBIG STL11K to Focal Reducer Custom Adapter (for optimum backfocus distance)
0.85x Focal Reducer (PN 7887)
Canon EOS Camera Adapter (PN 5005)
Front Helical Focusser Adapter Set (PN 7130)
Rotating Ring (yes, manual camera rotation) (PN 7352)
Helical Focusser (PN 7835)
Pair of rings (white)
Extension tubes/spacers - PN 7601, 7602, 7603, 7504
Adapters various - PN 7920, 7424, 7507, 7522, 7502
2" EP Holder (PN 7508) Short
2" EP Holder (PN 7509) Long
The main parts of this package new would cost you approx $1700 (now superceded by the 77EDII), Reducer is $369, STL-BORG Adapter $148, Helical Focusser - $206, Rotating Ring $99). However, the package includes many other bits and pieces as above.
The OTA body (which does not contain any optical element) has slight cosmetic marks.
Wonderfully light, great for portability, and for astrophotography, is best configured with the helical focusser at the front. Therefore, no sag at the camera end
I have used this visually but principally as a luxury guidescope, even though I bought custom adapters go to between it, the Borg 0.85x focal reducer and STL11K.
Sale price excludes shipping and insurance. Paypal extra.
