Sell or trade my Celestron CR150HD's original equipment diagonal and multi coated 20mm eyepiece. Both are about 1.5 years old and come with original boxes. Optics in great shape, a few scratches on the chrome from set screws. I've gone to 2" optics in this eyepiece size range. $27 each plus $3 shipping. Buy both and I'll pay shipping. Or trade for equivalent 1.25" 10mm eyepiece. Money Orders/certified checks. Personal checks held till they clear.
