This 12" Dovetail Sliding Bar was designed with short instruments in mind. The middle portion of the plate is raised 0.5" above the front and back sections. As a result, the plate is long enough for optimal movement without causing interference with the dewcap or focuser. The plate is ribbed on the underside to reduce weight. Use with our 10" Dovetail Saddle Plate (DOVEDV10), 16" Dovetail Saddle Plate version with 3-clamps (DOVELM162) or other similar saddle plates. The SBD12 is too short to be used with our older style 16" plates, the DOVELM16, or DOVELM16S that have only 2 clamps.
Attach SBD12vdirectly to the bottom of mounting rings of these scopes:
Refer to the hole pattern document below to determine your mounting options
- 92mm f6.65 Stowaway - attach directly to Astro-Physics rings
- 105mm f6 Traveler - a spacer bar is preferred to allow more finger room on the focuser, but is not required.
- 110mm f6.0 StarFire GTX - attach directly to Astro-Physics rings
- 130 mm f6.3 StarFire GT or GTX - attach directly to Astro-Physics rings
- 130 mm f6 StarFire (original version) - attach directly to Astro-Physics rings
- 130 mm f8 or f8.3 StarFire, 140 mm f7 StarFire, and 155 mm f7 StarFire or similar instruments - you may use with Astro-Physics Riser Blocks (SBDAPB) if you choose to attach rings in the outer hole positions. This will space the rings approximately 10" apart. The blocks rest completely on the sliding bar and do not extend off the side.
- 90 mm f5 Stowaway (1999 vintage) must be mounted by using the 5.5" sliding bar (SB0550) (discontinued) as a spacer to allow additional clearance for the dew shield.
- TeleVue or Takahashi - Attach clamshells directly to the SBD12 using M8 socket head screws.
- Losmandy Adapter Blocks or AP Riser Blocks (SBDAPB) using 3.5" hole spacing
- Instruments that have ¼-20 center holes in the mounting rings.
Use as an accessory plate:
The following instructions assume that you are using the SBD12 or SBD16 on the bottom of your mounting ring. The goal is to attach another SBD12 to the top of the rings so that the male dovetail portion is facing up. This allow accessories with female D-style dovetail channels to be used. The method of attachment will depend on the hole pattern on the top of your mounting rings. Refer to the Astro-Physics Ring Hole Pattern diagram to confirm the hole pattern of your rings.
47RING, 55RING2 or 65RING2: Attach with 1/4-20 screws (provided) in the holes spaced 2.362" apart. You can also use the center holes, but it is always better to use two screws rather than one.
55RING or 65RING: You must use Astro-Physics Riser Blocks (SBDAPB) between the mounting rings and the SBD12. Notice that the holes on top of the rings are offset from the middle, but the holes on the bottom of the rings are on the centerline. For this reason, you cannot attach the SBD12 directly to the top of the rings. 1/4-20 screws are provided to attach the SBD12 to the SBDAPB.
Use the SBD12 accessory plate with the following items:
- Losmandy Dovetail Plate Adapter (LMDVA). This will allow you to attach the following items: Quick Release Finder Bracket for 10x60 finder (S1060QRM), TeleVue Starbeam (STARFMD) and various other accessories.
- Additional adapters with a female D-style series dovetail channel. Numerous accessories can be attached to these adapters, i.e. communication and power distribution devices, dew heaters, etc.
