We
can mount your telescope tube in our Standard Mount
within the set fitting limits
if it uses any bearings like these (or others), or
if it has no bearings or has tube rings.
Standard 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 (please use a
cloth tape measure).
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.
Kits
arrive rough sanded. All parts (screws, dowels, teflon,
laminate) included. Screw and dowel holes all predrilled
and countersunk. Requires fine sanding, paint or finish,
glue bearing laminate and assembly.
Add
manual setting circles.
The standard mounts includes laser inscribed
12" altitude bearings.

Standard mount fitting requirements:
Maximum
outside telescope tube diameter:
13.10"
Tube
mounted in rings? We can add bearings if rings
width flat to flat are maximum:
13.60"
Maximum
balance point distance (instructions in green
below):
23.00"
We can compute your tube's swing through room
for you at right. Or use the example computation
below.
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.
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.
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.
