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.
