These mounts are a preset design and size. For taller and/or wider
sizes please see our custom solid
or collapsible
mounts.
Standard Solid
Mounts fit telescopes with:
- Tubes up
to 13.1" outside diameter (measure using a cloth tape measured).
- Tube rings
up to 13.6" outside flat to outside flat.
- Tubes with
less than 23" of swing-through room maximum. Measured from
the tube's balance point to back/mirror end; see "fitting
requirements" below.
We can fit
your telescope tube to our Standard Mount within the limits above
if it uses any bearings like these (or others), or if it has no
bearings or has tube rings
Standard Mount Kits arrive rough sanded. All parts included, screw
and stiffening internal dowel holes all predrilled, countersunk.
Requires fine sanding, paint or finish, glue bearing laminate
and assembly. Spray finished unassembled are also available.

II digital or manual

The standard mounts includes laser inscribed 12"
altitude bearings.

We can compute your tube's swing through room for
you. Or use this example computation. This example
is a 10" outside diameter tube with 20"
balance point. If your tube has a protective ring
on the back end, use the ring's diameter instead.
Determine your balance point by having heaviest
eyepiece in focuser, and all finders you use installed.
Then roll the tube over a broomstick to see where
it wants to balance. Measure from there to the end
of the tube.
1. Determine 1/2 the tube outside diameter: 5".
2. Square
that number: 25.
3. Square the 20" balance point dimension:
400.
4. Sum the two squared numbers: 425.
5. Obtain square root of that sum using a calculator:
20.62".
That square root equals the minimum required swing
through room for your tube.
7. Add one half inch (or more) to clear azimuth
bearing nut: 21.12".
8. In this example, 21.12" fits within the
allowed 23" maximum swing through room.
