Guider Layout & Setup 

 

The guider is fairly straightforward and consists of the main 
guider body, a pick-out prism, guide camera drawtube, and 
removable/rotating T-thread adapter.  To assemble your 
system, loosen the 3 locking screws that hold the T-thread 
adapter in place and remove the adapter from the guider body.  
Thread the adapter into the front of your camera adapter (DSLR 
T-ring) and firmly tighten. (

You may need to use a spacer ring or 

alternate adapter in order for the 
guide camera to reach focus; see 
specific configurations later).

  Re-

attach the adapter and camera to 
the guider body.  Before tightening 
the locking screws adjust the 
orientation of the camera so the 
detector is “square” with the edge 
of the prism.  Look through the 
guider into the camera to view this 
alignment.
