SMK Standard Mount Kit

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. Finished Mount Kit same as Kit Mount, but comes spray finished, laminates glued.

Add manual setting circles.
The standard mounts includes laser inscribed 12" altitude bearings.
Photo shows our 18" altitude bearing.

Fitting requirements and Swing Through Room


Telescope bearings mounted onto tube maximum outside tube diameter:
 
13.10"
Telescope mounted in rings - outside diameter flat to flat maximum distance:
13.60"
Maximum distance below balance point (balance point instruction below):
23.00"


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.
