Astro-Physics SBD12 12" Dovetail Sliding Bar for D-Style Saddle Plates
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.
Weight: 1.9 lb. (0.86 kg) . The plate is ribbed on the opposite side to reduce weight.
Includes screw packet for various configurations.

Attach directly to the bottom of mounting rings or with a spacer bar
130mm f6.3 StarFire “Gran Turismo”, 105mm Traveler, 130mm f6 StarFire (original version) - attach directly to Astro-Physics rings. With the Traveler, a spacer bar is preferred to allow more finger room on the focuser, but is not required.
130mm f8 or f8.3 StarFires, 140mm f7 StarFire, and 155mm f7 StarFire or similar instruments – use with Losmandy blocks (LMAPBLOCKS) in the outer hole positions. This will space the rings approximately 10" apart. The LMAPBLOCKS rest completely on the sliding bar and do not extend off the side.
Instruments that have ¼-20 center holes in the mounting rings.
90mm f5 Stowaway must be mounted by using the 5.5” sliding bar (SB0550) as a spacer to allow additional clearance for the dewcap.
Attach your TeleVue or Takahashi clamshells directly to the SBD12 using M8 socket head screws.
Use with our 8.5" Dovetail Saddle Plate (DOVELM2), 16" Dovetail Saddle Plate version with 3-clamps (DOVELM162) or other similar plates. The 12” Sliding Bar is too short to be used with our older 16" plates: DOVELM16, DOVELM16S or the DOVELM162 version that has only 2 clamps.
Use as an accessory plate
Attach directly to the top of rings using a single center hole or use Losmandy AP Blocks (LMAPBLOCKS – purchased separately) to attach the 12” Sliding Bar to the top of the mounting rings (assuming that the surface is flat and has the Astro-Physics hole pattern - two 10-32 tapped holes with 3" spacing) . Use with the following accessories:
Losmandy Dovetail Plate Adapter (LMDVA) . This will allow you to attach the following items: Quick Release Finder Bracket for 8x50 finder (S850QRM), TeleVue Starbeam (STARFMD) or Qwik-Point Finder (QWIKMD), 60 x 700mm guidescope with 3.4" guidescope rings (previous product no longer available) and various other accessories.
