I purchased this solar filter about two years ago in anticipation of a scope I never ended up getting. I've used it a number of times on some of my other scopes with various adapters I fasioned, but it's time to sell it and get the proper one now. The filter is in excellent condition, with no scratches at all.
I built this nice wooden case for it out of mahogany with brass hinges and clasp. I'm no master craftsman, but it is quite nice if I do say so myself.
I'll sell both for $60, including shipping in the continental US, or trade for a Thousand Oaks (or equivalent, maybe) that fits an ETX-105.
I can take PayPal or a money order if you like.
