The 15" version of the AP dovetail plate is suited for the 130 f/8 StarFire EDT, 155 f/7 StarFire EDFS, ARO Maksutovs, Takahashi scopes and other instruments of similar size. The knob assembly features a brass pin with a tapered end to hold your sliding bar firmly without marring the aluminum.
Use with the 15" Sliding Bar (SB1500).
Applications for AP 15" Dovetail
As a Mounting Plate:
As an Accessory Plate:
Attach to the top of Astro-Physics mounting rings (diameters 5" - 8") or rings from Parallax Instruments that have the Astro-Physics hole patterns (you can request it).
Note, you must also use a mounting plate on the bottom of the rings with the same distance, i.e. the DOVE15, FP1500, 1200RP15, 900RP, FP1800 (only if you use the innermost hole spacing) or the cradle plate of the Astro-Physics 800 mount (prior model). The distance between these pairs of holes is 13.75".
Please note that your telescope rings must be tapped with two 10 - 32 holes spaced 3" apart to accommodate this plate as an accessory plate. Some of our earliest rings were produced before we included this set of holes in our standard hole pattern. To confirm that your rings are appropriately tapped, please refer to the Astro-Physics Mounting Ring Hole Pattern document.
Note also that this plate will not accept Vixen style plates (sliding bars) like the Losmandy V-series. This newer Vixen specification is slightly narrower than the long-established Astro-Physics 15" specification and has a much less angled bevel to the dovetail. This dovetail saddle will not adequately clamp onto the smaller Vixen style plate (sliding bar).
