Astro-Physics 22" Sliding Dovetail PlateThis robust male plate from Astro--Physics features a myriad of holes throughout the entire length that can accommodate a variety of instrument configurations at various balance points. The AP SB3622 plate can accommodate instruments that have hole spacings of 3.2 (Astro-Physics hole pattern), 3.5, 5.5 and 7.45. These holes extend from one end of the plate to the other allowing you to space rings as you wish. You can also use two (or even three, depending on instrument size) AP 16" Dovetail Plates in a side-by-side configuration for multiple instruments. The DOVELM162 is drilled to attach directly onto the SB3622. The DOVELM162 also features lock-down knobs that can be firmly tightened with an allen wrench..
Achieving a Two-Part Mounting System with 22" Dovetail Saddle Plate
When you combine the Astro-Physics 22" Dovetail Plate with the 22" Dovetail Saddle Plate (DOVE3622, sold separately), you will achieve a massive and sturdy two-part telescope mounting system for your AP 3600GTO mount that provides the convenience of a dovetail with the security of a fixed mounting plate. This two part system was designed by Astro-Physics for strength, rigidity and versatility. The 3600 dovetail system can be set up for tip-in or slide-in of the dovetail sliding bar. Safety slots on the saddle plate coupled with the sliding bar's safety stop will help keep accidents from happening.
For permanent installations, a series of matching through-holes in the saddle and tapped holes in the sliding dovetail plate allow the setup to be bolted into its final position through both plates once adequate balance is achieved. As an added feature, the saddle plate has two cable-routing channels on the eyepiece end, each 2" wide and approximately 0.5" high. These channels allow you to access the large opening at the top of the dec axis to run your cables through the mount. Refer to the cabling section of the manual to see how easy this is. The dovetail plate is drilled on the underside of the eyepiece end so that you can attach a plate that can be customized as a cabling port.
