Astro-Physics Saddle Pate for Mach1GTO
Astro-Physics Saddle Pate for Mach1GTO
The Astro-Physics Mach1GTO doesn't include a saddle plate when you purchase the mount. AP has several options to choose from that will allow you attach your telescope.
8.5" Dovetail Saddle Plate for D-Style Plate
This plate is made by Astro-Physics and can be used with a variety of mounts. If you already own the 13.5" male Losmandy D-style plates, this is the dovetail for you. The knob assembly features a brass pin with a tapered end to hold your sliding bar firmly without marring the aluminum.
A center hole on the knob side allows you to move one of the knobs to accommodate the short (7") Losmandy Universal plates. The short Losmandy plates should only be used with one of the knobs moved to the center position. Otherwise, the knobs of the DOVELM2 are spaced too far apart to grip the short plate properly. Make sure that you orient the DOVELM2 so that one of the knobs is always at the objective end of the plate. Otherwise, you will not be able to utilize the safety screw on the bottom of the male dovetail. Using the middle hole with the 7" plate gives over three inches of travel for balancing.
Warning: Some Celestron plates (2004 - recent production) do not anchor securely in the DOVELM2 . We encourage everyone using a plate manufactured by Celestron to test that plate in the DOVELM2 before mounting their telescope, in order to ensure that it can be locked down firmly.
16" Easy-Balance Dovetail Saddle Plate for the D-Style Plate
This 16" Dovetail Saddle Plate, designed and manufactured by Astro-Physics, is the ultimate in versatility for customers with instrument packages that are difficult to balance in conventional saddle plates.
A total of 8 mounting positions are available to provide a "best possible" orientation for either front-heavy or rear-heavy instruments - especially useful for today's heavy imaging configurations. This plate has an inherent 8" (20.3 cm) total offset capability, depending on how you position it on the mount. Due to the addition of a third, center clamp, the DOVELM162 can now maintain at least two clamps engaged on any Losmandy "D-style" or other "D-style" dovetail plate 7" or longer.
As with all of our dovetail saddle plates, it is very easy to attach dovetail plates. Simply tilt your D-style plate, with the scope attached, into position. Then tighten the knobs. There is no need to struggle as you try to insert the Losmandy plate (with your heavy telescope attached) into the end of the dovetail saddle, as with some dovetail saddle plate designs.
Warning: For several years, beginning approximately 2004 until more recently, Celestron delivered their scopes with a dovetail mounting plate that had a different specification. These plates do not anchor securely in the DOVELM162. We encourage everyone using a plate manufactured by Celestron to test that plate in the DOVELM162 before mounting their telescope, in order to ensure that it can be locked down firmly.
Astro-Physics 15" Dovetail Saddle Plate
The 15" version of our 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
This saddle requires that you use the 15" Sliding Bar (SB1500), which is sold separately.
15" Flat Mounting Plate
This machined aluminum mounting plate measures 15" x 4.6" x 0.5". Two keyhole slots that measure 3.2" between centers are provided at each end of the plate. The distance between these pairs of holes is 13.75". You can drill additional holes to suit your needs. The plate weighs 3.3 lb. (1.5 kg.).
If you plan to use an accessory plate on top of your rings, we suggest the 15" Dovetail Plate (DOVE15). All Astro-Physics rings (except the Traveler and Stowaway) are predrilled to accept the DOVE15. Rings from Parallax Instruments can also be drilled with the Astro-Physics hole pattern.
15" Ribbed Mounting Plate
Astro Physics CNC machining center started with thick aluminum plate and carved out the excess material leaving a strong rib support structure. The finished plate is 0.75" thick, 14.75 " long and 6.5" at its widest point.The width of the plate tapers to 4.75". A pair of keyhole slots that measure 3.2" between centers are provided at each end.The distance between these pairs of holes is 13.75". Due to the ribbed structure, you may not be able to drill additional holes to suit your mounting rings. The plate weighs 2.3 lb. (1.0 kg.).
Since the rings will be spaced 13.75" apart (center to center), you can use the 15" Dovetail Plate (DOVE15) as an accessory plate on top of your Parallax Instruments rings with the Astro-Physics hole pattern.
18" Flat Mounting Plate
This larger machined aluminum plate is available for the Mach1GTO, 900, 1100, 1200 or 1600 mounts. It is 18" long and 7.5" at its widest point in the center. The width of the plate tapers to 5.5" at each end. Four pairs of keyhole slots that measure 3.2" between centers are provided. The two inner pairs are 13.75" apart and the outer two pairs are 17" apart. You can drill additional holes to suit your needs. The plate weighs 6.2 lb. (2.8 kg.).
If you use the innermost holes, you have the option of using the 15" Dovetail Plate (DOVE15) as an accessory plate on top of your Astro-Physics mounting rings. Rings from Parallax Instruments can also be drilled with the Astro-Physics hole pattern.
Please Note: While the 18" Flat Mounting Plate will fit on the Mach1GTO without a problem, you should carefully consider whether the mount is being overloaded. If your instrument is so big that it requires the FP1800, it is probably too big for the Mach1GTO.
