In order to assemble your mount fully, you will need the following items sold separately:  

 

Telescope mounting plate – many choices to fit your telescope and observing needs.   See detailed section later 
in this manual. 

 

Pier or Tripod 

o

 6” 

Eagle

 Adjustable Folding Pier (EAGLE6) 

o

 

Astro-Physics 6” Portable Pier – 6 sizes from 24” to 62” tall (6X##PP) 

o

 

Adjustable Wood Tripod (AWT000) 

o

 

Adjustable Aluminum Tripod (SDS400)  This tripod can be used, but is not recommended for heavier 
loads. 

o

 

Adapt to your own custom pier or tripod with our Tripod Adapter (ADATRI) 

 

Counterweights – 6 lb. (6SLCWT) and 9 lb. (9SLCWT) are available. (5 lb., 10 lb. and 18 lb. with optional 
counterweight shaft – see below.) 

 

Portable rechargeable 12 volt battery pack or a power converter to convert your household AC current to DC 
current of 12 – 16 volts at a minimum of 5 amps. We offer a 13.8 volt 5 amp converter (PS138V5A) and a 15 
volt 10 amp converter (PS15V10A).  

Many of these items will be discussed throughout these instructions. Several additional options are available:

 

 

 

Optional 10.7” total length x 1.875” diameter Counterweight Shaft (M1053) and Safety Stop (M12676) for use 
with 5 lb. (5SCWT), 10 lb. (10SCWT) and 18 lb. (18SCWT) counterweights. Handy for travel or if you already 
own a 900 or 1200 series mount. 

 

Polar Alignment Scope with Illuminator  (PASILL4) – for quick and easy polar alignment 

 

Pier accessory trays: A flat accessory tray with raised sides, a tray with eyepiece holes, a control box adapter 
bracket and two support bar options are now available to fit the 6” 

Eagle

 Adjustable Folding Pier, some sizes of 

the 6” Portable Pier and both tripods.  They are handy and attractive places to keep your eyepieces and other 
astro-gadgets close at hand! The Control Box Adapter is included in mounts shipped starting in April, 2007. 

 

Santa Barbara Instrument Group CCD Imaging cameras, STV, ST-4 Autoguider or other imaging camera- if you 
plan to pursue CCD imaging or astrophotography 

 

PEMPro™ (Periodic Error Management Professional) is a Windows software application that makes it easy to 
characterize and reduce periodic error.  PEMPro™ will analyze the performance of any mount that is equipped 
with a CCD camera and compatible camera control software.  PEMPro™ gives you powerful tools to program 
your mount's periodic error correction firmware to achieve the best possible performance for your mount.  
PEMPro™ dramatically improves guided and unguided imaging resulting in better images and fewer lost 
exposures.  While the periodic error of your 

Mach1GTO

 will be 7 arc seconds or less, you can reduce it even 

further to maximize performance without auto-guiding.  

Note on Encoders:

  Mounted encoders can not be used with the 

Mach1GTO

   They are not needed since the go-to 

functions of the mount are so much more accurate. The encoder that is built into the servo motor itself has a resolution of 
0.05 arc seconds vs. 324 arc seconds for mounted encoders.
