Description
All GSO Crayford focusers for reflector telescopes include a mounting base. However, you can also purchase additional bases. Bases fit on all single and dual speed GSO 2" reflector Crayford models. Not for use with GSO's 1.25" Crayford focuser. Aluminum with black anodization. Available in five models.
Type 0: Base Plate for 6" Telescopes - GSO (176mm Base Curve Diameter)
- Base plate curve diameter: 6.93" (176mm)
- Base plate dimensions: 3.54" x 3.54" (90mm x 90mm)
- Hole Spacing (center-to-center along telescope tube/optical axis): 70mm (2.76")
- Hole Spacing (center-to-center perpendicular to telescope tube; straight line measurement): 73mm (2.87")
- Hole Spacing (center-to-center perpendicular to telescope tube; measured along curve of base plate): 74mm (2.91")
- Inside diameter of central hole: 3.07" (77.9mm)
Type 1A: Base Plate for 8"/10" Telescopes - GSO (230mm Base Curve Diameter)
* Direct bolt-on replacement for stock R&P focusers on 8"/10" GSO dobsonians sold under the following brand names: Antares, DSH, Hardin Optical, Zhumell, DBA, and many others.
* Direct bolt-on for Celestron Star Hopper and Meade Light Bridge telescopes.
* May work for some Orion XT dobsonian telescopes. Please measure hole spacing on your scope before purchase.
- Base plate curve diameter: 9.06" (230mm)
- Base plate dimensions: 3.54" x 3.54" (90mm x 90mm)
- Hole Spacing (center-to-center along telescope tube/optical axis): 70mm (2.76")
- Hole Spacing (center-to-center perpendicular to telescope tube; straight line measurement): 73mm (2.87")
- Hole Spacing (center-to-center perpendicular to telescope tube; measured along curve of base plate): 74mm (2.91")
- Inside diameter of central hole: 3.07" (77.9mm)
Type 1B: Base Plate for 8"/10" Telescopes - Non GSO (230mm Base Curve Diameter)
* We got a bunch of these from a supplier and aren't sure what telescopes these would work with since the hole spacing is a bit different than the GSO plate above. Perhaps it is just the plate your non-GSO scope needs.
- Base plate curve diameter: 9.06" (230mm)
- Base plate dimensions: 3.67" x 3.67" (93mm x 93mm)
- Hole Spacing (center-to-center along telescope tube/optical axis): 74.5mm (2.93")
- Hole Spacing (center-to-center perpendicular to telescope tube; straight line measurement): 73mm (2.87")
- Hole Spacing (center-to-center perpendicular to telescope tube; measured along curve of base plate): 76mm (2.99")
- Inside diameter of central hole: 3.07" (78.0mm)
Type 2: Base Plate for 12" and Larger Telescopes - GSO (303mm Base Curve Diameter)
* Direct bolt-on replacement for stock R&P focusers on 12" GSO dobsonians sold under the following brand names: Antares, DSH, Hardin Optical, Zhumell, DBA, and many others.
* Direct bolt-on for Celestron Star Hopper and Meade Light Bridge telescopes.
* May work for some Orion XT dobsonian telescopes. Please measure hole spacing on your scope before purchase.
- Base plate curve diameter: 11.93" (303mm)
- Base plate dimensions: 3.54" x 3.54" (90mm x 90mm)
- Hole Spacing (center-to-center along telescope tube/optical axis): 70mm (2.76")
- Hole Spacing (center-to-center perpendicular to telescope tube; straight line measurement): 73mm (2.87")
- Hole Spacing (center-to-center perpendicular to telescope tube; measured along curve of base plate): 74mm (2.91")
- Inside diameter of central hole: 3.07" (77.9mm)
Type 3: Flat Base Plate
- Base plate dimensions: 3.62" x 3.62" (92mm x 92mm)
- Hole Spacing (center-to-center along telescope tube/optical axis): 76mm (2.99")
- Hole Spacing (center-to-center perpendicular to telescope tube): 76mm (2.99")
- Plate thickness: 0.31" (8mm)
- Inside diameter of central hole: 3.09" (78.5mm)
Additional Notes:
* You may need longer screws for some plates above as compared to the ones you already have on your telescope (available for a few cents each from any hardware store).
* Can be adapted to most other Dobsonian and Newtonian telescopes by drilling additional holes on the OTA if necessary.
