APPENDIX F: PRE-DEFINED PARK POSITIONS

The Mach2GTO does not require starting from pre-defined park positions, but it is often helpful to finish the evening in one.  

Recommended:

  

Park 3

 is a safe and balanced position.  

Park 2

 is a convenient position for loading and 

unloading your scope.  

Park 5

 is a safe, low profile position with minimum cable twisting.
