For Sale: New TPO 6" f/9 Ritchey-Chretien Astrograph $295
« on: November 14, 2017, 03:43:23 PM »
At the recent Advanced Imaging Conference (AIC) in San Jose, I won a raffle prize of a TPO 6" f/9 Ritchey-Chretien Astrograph with 2" focuser donated by OPT in Oceanside, CA.  As I already have many astrographs, I am selling this brand new astrograph at $295, a substantial discount. The optical tube is still sealed in its plastic bag!  The specifications for the system are:
Aperture           152 mm (6")
Focal Length     1370mm
Focal Ratio        f/9
Focuser              Design Crayford
Focuser Size      2"
Manual Focusing
Manufacturer      TPO   (Taiwan)
Optical Design     Ritchey Chretien
Back Focus from focuser:  150mm

This could be a good starter astrograph for imaging at this price.

For more information, see the OPT website on this astrograph:
