Dobsonian
Mount Choices
Standard
Solid Mounts
- This is the most
economical mount we offer. The standard solid mount has set requirements:
IMPORTANT: Your telescope must fit within these dimensions, no changes
possible:
Maximum
depth of mount from balance point (center of altitude bearing) to
mirror end of the telescope tube - 23 inches.
Maximum
width of tube, or tube with bearings - 13.1 inches maximum with
existing bearings, or 13.6 inches with existing rings.
|
- Telescope tube
can have (or not have) altitude bearings or a mounting ring set.
- Telescope tube
without altitude bearings or a ring set require drilling two 3/8"
holes at the balance point for mounting our included 12" altitude
bearings.
- Telescope tube
with existing altitude bearings - discard or use them with our included
12" altitude bearings.
- Telescope tube
in a ring set: our altitude bearings can easily attach your ring set..
- Standard Mounts
use only eleven screws and eight 3/8" wood dowels. Assembly is
straightforward and easy and we're happy to help if needed.

altitude and azimuth setting circles with pointers. Or order only an
azimuth setting circle.

digital setting circles. We install if you purchase though AstroGoods.

Custom
Collapsible Mounts
-
Designed
eapecially for limited storage/transportation considerations.
- Does not use
screws and dowels. Uses
heavy duty anodized piano hinge instead.

boards are unitized, staying permanently attach together.
Materials
We
use 3/4" (18mm) Baltic Birch plywood for rocker boxes, ground
boards, bearings and clamshell rings. Altitude and azimuth bearings
use Teflon and Formica Crystal 909-42 laminate. All parts are included,
assembly of kits is designed to be very easy; solid mounts usually
use only 11 screws and 8 dowels. Dowel are internal between abutting
front, ground and side boards to lock them in place and add stiffness.
Custom "tall" mounts may require additional screws and
dowels.
