Im selling my Orion Telecompressor f/6.3. Just bought a scope thats an f/4 so i no longer need it. I never used it and to my knowledge has NEVER been used. Im asking $70 + shipping. In a trade im looking for some type of Dew shield or Dew strap for a 10" scope. OR an O-111 nebula filter. Let me know what you have and what condition its in.
