I have two 2" - 1.25" compression ring eyepiece adapters available for sale. The one on the left in the photo below is *new* from Joe Cartolano, the other on the right is in excellent condition, I'm not sure of the manufacturer. Both are threaded for 48mm filters.
$22 each shipped in the CONUS. Payment by Money Order, Bank Check, Personal Check (ship when clears), and PayPal (existing funds or bank transfer only. NO Credit Card funded transfers).
