I received this in a trade thinking that it might fit my ETX 90, but its just a tad too big. I've since bought one that does fit my scope and I need to find a home for this one.
This is a Baader FILM filter, it is 5" in diameter and should accomodate 4-5" scopes. An inner foam tape lining and three nylon thumbscrews will secure it to your OTA. It is in great condition (no pinholes, etc)and comes with its own case.
Asking $45 shipped (con US only) via Paypal (+3%) or money order.
Would also trade for a UHC filter if ya have one ;-)
