Aparture fever strikes again. Siebert Optics black knight binoviewer complete with focal reducer for SCT. Two months old in excellent shape. Plus Celestron C8 fastar compatible SCT two and a half years old, it has some light scratches on the tube nothing serious and the optics are in excellent shape. I will trade for a Celestron C 9.25 SCT, must have excellent optics or I will sell for $900.Paypal prefered no credit card.
Thanks for looking....Cornelius
