Dobsonian Mount Choices



What do you receive with a kit or finished mount?

Kit: Wooden parts (rocker box and ground board) arrive rough sanded with 80 grit, predrilled and countersunk. Parts Include all necessary screws and dowels in their holes, azimuth and altitude bearings laminate strips ring along with all bearing Teflon pads. You fine sand, glue laminates with contact cement, paint or finish. Ships unassembled. Assembly help/advice is available by e-mail.
Finished: In addition to above items in a kit, all wooden items are fine sanded, sealed with three coats General Finishes gloss polymer. Laminates are glued. You only assemble.




Mount Weights

All mounts are designed to minimize weight while maintaining structural rigidity. AstroGoods mounts will be significantly lighter weight than a comparable commercially manufactured OEM equivalent mount due to use of Baltic Birch plywood instead of porous (subject to wicking moisture in dewy conditions) and heavy particle board, chosen as it is inexpensive (read: cheap).

The large majority of orders we fulfill are custom mounts, so sizes and weights vary. Our Apertura style mounts is a standardized design and can provide an idea of weight savings we achieve, based on user feedback. Weights may vary with design changes:

Apertura mount weights comparison:
12" OEM mount 38 lbs.,      AstroGoods 23 lbs.
10" OEM mount 31 lbs.,      AstroGoods 19 lbs.
  8" OEM mount 28 lbs.,      AstroGoods 15 lbs.

We also offer custom solid lightweight mounts by request!

 




Standard Solid Mount
Kits and Finished

Our most economical mount. Fits up to most 10" telescopes.




Dimensional requirements

Standard solid mounts are not customizable and only for telescopes fitting within these dimensions:

23" maximum telescope tube balance point. How to measure:
Place heaviest eyepiece in focuser, add all finders you will be using.
Roll tube over fulcrum to determine where it tries balancing.
Measure from approximate balance point to back/mirror end of tube (or knobs if protruding).

13.6" maximum space inside mount side boards.
13.1" maximum diameter telescope tubes will fit, allowing 0.25" open space between tube and inside of each side board.
13.6" maximum if using tube rings to attach our altitude bearings, measured from outside flat to opposite outside flat.

If you are unsure e-mail us here and we can advise whether your telescope will fit.

 


About standard solid mounts:

Optional: Manual setting circles. Integrated or separate mount height adjustment stand.

Custom Solid Mounts
Kits and finished

Our
most popular mount, designed custom to fit your tube saving size and weight, or to add additional strength.

About custom solid mounts:

  • Custom designed to fit your telescope, thereby reducing size and weight.
  • Can be designed to place focuser at a preferred height.
  • Dowels are internal/hidden between abutting front, ground and side boards to lock in position for stiffness.
  • Additional information: What do you receive with a kit or finished mount?
Optional: Altitude bearings (12" or 18"). Clamshell rings with altitude bearings. Manual setting circles. Mount height adjustment stand, separate or integrated.







Custom Collapsible Mounts
Kits and finished

Designed for storage and transportation considerations, custom to fit your tube saving size and weight
.

 



Included with custom collapsible mounts:

Optional: Altitude bearings (12" or 18"). Clamshell rings with altitude bearings. Manual setting circles. Mount height adjustment stand, separate or integrated.


Folding a collapsible mount:

1) Mount in upright assembled position.
2) Left side board is hinged to front board on front inside, allowing it to swing inward to back of the front board.
3) Front board is hinged on outside to right side board. Left and front boards in unison swing forward...
4) And continue around 270 degrees...
5) to meet outside of right side board. Right side board is hinged on inside bottom edge to rocker box ground board.
6) Entire assembly lays down inward onto rocker box bottom board and ground board.

Mount folds flat to 5" height.



 


If your tube needs altitude bearings, or you wish to upgrade to larger altitude bearings we offer two sizes with our mounts:

12 inch outside diameter (left photo) full circle bearings. Hand holds incorporated. Laminate applied to half the circle.
18 inch outside diameter (right photo) half circle bearings. Hand hold openings are incorporated. Laminate applied to entire half circle.

Bearings attach to your telescope through a 3/8" hole centered in the bearing. Inside facing arced braces secure bearing to tube. Or:
Bearings can attach to your existing ring set, on the drilled flats. Or:
Bearings can attach to outside of clamshell rings we supply. Allows repositioning forward/back or rolled for focuser position.

18 inch altitude bearings suggested for 10" and larger telescopes and/or long tubes. Provide more stable balance and finer incremental altitude movement.

 

 

Clamshell Rings allow:

  • Attaching altitude bearings to your optical tube without drilling holes.
  • Provides ability to rotate tube and reposition of focuser.
  • Allows moving tube forward or back if weight is added (binoviewer for example) or removed to tube.
  • Adds 1.5" to the width of a mount.
  • Bottom clamshell boards connected by heavy duty anodized aluminum piano hinge.
  • Top boards secured with by thumbscrew transversally through 3/8" holes into 1/4-20 wood insert. Cannot pull out.
  • Top of clamshell is gapped 0.1875" to allow tightening securely to your tube. Add adhesive back felt or other cushioning if desired.




Materials:

  • 3/4" (18mm) Baltic Birch plywood is standard for most of our wooden parts.
  • Altitude and azimuth bearings use Formica Crystal 909-42 laminate riding on Virgin Teflon pads.
  • Small parts for assembly may include:
    #8x1.25" exterior grade Torx wood screws with bronze epoxy coating provides 4 layers of corrosion protection.
