♦ Bracket Info.
The NexStar Bracket consists of three machined
aluminum parts, the clamp base, dovetail clamp, and dovetail bar. A
machined adapter ring
is also provided with the NexStar 114 clamp to mount to its larger fork arm.
The clamp base bolts directly to the declination drive gear in place of the
Celestron/Orion plastic tube clamp. The dovetail clamp mounts to the base and
provides the dovetail groove and large threaded brass clamp knob (the image
above shows the clamp base and dovetail clamp joined). The supplied
dovetail bar is anodized black (no longer silver) and machined with a central 1/4-20 threaded hole
plus two 1/4" wide central mounting slots that allow easy mounting with many
telescopes and tube rings. The dovetail clamp uses the Vixen dovetail
standard (i.e. Celestron, Synta,
Orion, and other Vixen ‘clones’), so you can also directly attach any
already has a compatible dovetail bar. For attaching scopes which have
mounting rings that require two mounting screws, additional mounting holes can
easily be drilled into the dovetail bar flanges.
There are two versions of the clamp available. The NB80
fits either the NexStar 60 or NexStar 80 mount as well as the Orion StarSeeker
70 or 80, and includes a 4.7" long
aluminum dovetail bar. The NB114 is designed to fit the NexStar 114GT and
the new NexStar130GT mounting as well as the Orion StarSeeker 114/130, and includes a 7.1" dovetail bar. Additional
dovetail bars are available inexpensively, in two lengths (4.7" and 7.1"), to
permit you to quickly exchange among multiple telescopes. Each bracket comes with illustrated
instructions (its quite simple) and a 4mm metric allen wrench for installation.

"Just wanted you to know - I purchased the Baader NexStar bracket a while
back, and finally got around to ordering a NexStar 80. I've attached your
bracket, and mounted a Tak FS78. I also discarded the alum legs and put the
mount on proper oak legs. Wonderful setup!! Easy to move around,
transport, etc. and the mount handles the FS78 very easily. I'm still fiddling
with the computer to fine tune the tracking and GoTo precision, but pretty
decent out of the box. Thanks for a great product!!" HB Bartz
♦ Telescope Capacity
One question that often arises is just how
large or heavy a scope can these NexStar GT mounts adequately carry? The
little NexStar/StarSeeker mounts are built surprisingly well. The fork arm is die
cast aluminum, and its thick heavily ribbed cross section results in a very
rigid support. The drive gears are large in diameter and machined of metal
(not plastic like some inexpensive mounts), and the drive motors incorporate
closed loop optical encoders. In general, the NexStar/StarSeeker GT mounts
are well suited for all the 90mm and smaller refractors (under f/8), and 5" or
smaller SCTs and Maksutovs (i.e. the Orion Apex 127 and smaller).
While some users have been successful really loading these mounts down (one user
has mounted his Astro Physics 130 EDF on an N114 mount!), we recommend keeping
the total telescope weight under 10 lbs and ensuring that the drive gear tensions are
Shown below are a number of different scopes using the Baader

|The NexStar 80 mount shown below
and to the right is being used to switch between carrying a Questar 3.5"
Field Model and
a Takahashi FS-78C (8 lbs). This makes the perfect grab and go setup (and, though
the Questar already had a very fine small fork mount, the NexStar Goto mount
upgrades the little Questar to full Go To capability without giving up small
size and light weight). The original Celestron 80mm tube assembly will
have a permanent home as a super 80mm finder on a large Dobsonian.
