astrodon - MegaMOAG-DUAL

MOAG means Manual Off-Axis Guider, a non-moving part of your optical train.


The MegaMOAG™ is the largest member of our off-axis guider product line.  It is specifically
designed to accommodate the larger CCD detectors (36 x 36 mm), such as the Kodak KAF16803E and KAF9000E used
on larger telescopes with 4" accessories and extension tubes. It is a 4"-to-3" version of our popular 
MegaMOAG™, where the camera side accepts all 3" MegaMOAG™ adaptors.  Furthermore,  it
retains the thin 1.25" backfocus of MegaMOAG™, and is an ideal choice for systems having minimal
backfocus such astrographs made by Dream Telescopes. It also integrates nicely with the 4" systems at the back
of larger RC Optical Systems Ritchey-Cretien telescopes.
