Hi Roland:
The "GEG" isn't a filter, it's the Lumicon Giant
Easy Guider, the big gadget with a an OAG port for guiding and a reducer lens
that could be moved for ratios ranging from (I think) about 0.6 to 0.8. Fits on
the oversize SCT threads of the Meade 10 and 12 and (I believe) the big
Celestrons. Doesn't fit the 8s and 9.25 SCTs. With Lumicon going out of
business, these things may become scarce.
