The threaded rod (M6P1.0) on one side of the Borg 80 mm rings may be used for direct attachment to Losmandy GM8 universal plates, Vixen GP/GP-D dovetail plates, or the Televue Tele-pod. |
#7080 Borg 80 mm rings
--
suitable for Borg Series 80 optical tube assemblies (50 mm
to 100 mm objectives).
|
||||||||
|
Variations of the 7080 ring are the
#70801 and
#7083 rings.
The 70801 rings have a 1/4-20 threaded hole replacing
the threaded rods at the top of the 7080 rings. The 7083
rings have 1/4-20 screw clearance hole, allowing a
screw to be added and tightened from inside the rings.
This allows stacking of 708xx rings or other accessories
with 1/4-20 camera threads. If necessary, a
riser block may be added between the stacked
rings for additional spacing. The base of these
80mm ring variants is the same as for the 7080
part described above.

MR115/MR115D 115 mm rings
--
available with single (MR115) or double-sided
(MR115D) mounting for piggy-backed mounting of
accessories. These ring sets accomodate the Borg
Series 115 optical tube assemblies (100 mm to
125 mm objectives).
|
||||||||
|
MR140 140 mm rings -- handles the Borg Series 140 (150 mm objective) optical tube assembly. The base hole pattern is the same as the MR115/115D ring (above). |
||||||||
 
|
MRB1/MRB2* Riser Blocks -- adapt the 80, 115, and 140 mm rings to the hole patterns of Losmandy GM8 or G11 universal plates. Universal plates and other Losmandy accessories are available through Hutech.
|
||||||||
|
The MRB1/MRB2 riser blocks fit both the top and bottom
of the MR115D rings, allowing a Losmandy
universal plate to be mounted above the main
scope to accomodate Losmandy-compatible
dovetail accessories such as rings for
guide scopes or piggy-back camera mounts.
* The MRB2 riser blocks supersede the MRB1 blocks but are completely compatible in all dimensions. MRB2 blocks contain 1 additional hole in the center (rear counterbored) for added flexibility. |
