Glassspath Correctors (GC)

A Baader Glasspath Corrector (GC) fulfills two 
critical roles. Firstly, it corrects the glass path – 
that's the amount of glass through which light 
passes on its way through the prisms and which 
causes chromatic aberrations (colour errors) with 
fast telescopes. Secondly, the GC magnifies the 
focal length and moves the focal point of the 
main telescope. You will find more information 
about choosing the right compensator in the ad-
dendum starting at page 20. 
The GCs with a Z in the part number are for use 
with the Zeiss microbayonet. They are inserted 
"upside down", directly into the binoviewer.

A T-2 nosepiece in 1¼" (31,8mm, 

# 2458105

or 2" (50,8 mm, 

# 2408150

) is used to 

connect the binoviewer either through the 
pre-installed T-2 coupling nut or the optional 
TQC quick changer with a focuser/eyepiece 
clamp. They can also be used to use a T-2 
star diagonal at 1¼" or 2" focusers.
