(SOLD) Celestron 500mm f/5.6 lens. D=90mm.
The tube is a bit scrathed up but the
mirror and corrector look to be in great shape.
I just bought it two or three weeks ago.
It was not what I thought it was as far as diameter.
I have not tried it out but the focuser feels real smooth
and like I said the mirror and corrector look good.
It also comes with a Nikon ring.
The visual back has standard T threads so you can attach
the ring for your camera or it also looks like you could use
the lens as a spotting or astronomy scope with 1 1/4" accessories.
Paypal or money order.
Thanks for looking.
