SOLD!
6" f3.9 Newtonian custom built CF Astrograph

This newtonian astrograph has been assembled with premium components to optimise it for imaging. It has many
custom machined components to allow it to carry very heavy loads and to piggy back another heavy instrument without flexure.
This is not a lightweight OTA. It was originally designed to carry a large FLI Proline ccd camera and PDF focuser.

FEATURES:
-6" f3.9 full thickness pyrex primary mirror, manufactured by Astro Optical Supplies circa 1985
with very good optical figure
-2.6" Protostar ULF fused quartz secondary mirror, enhanced dielectric coated
-Protostar secondary mirror holder and spider
-brand new Feathertouch 2" focuser and levelling base
-custom made black-anodised primary mirror cell with USB powered fan
-2.5mm wall thickness carbon fibre tube from Public Missiles USA with clear epoxy finish
-custom made black anodised aluminium focuser base with full circumference reinforcing rings either side to prevent camera load flexure
-custom made clear-anodised aluminium tube saddle with over and under heavy duty Losmandy style dovetail and Cassady (USA) saddle plate, designed for zero flexure and carrying very heavy loads.
-Baader 2" coma corrector and Canon EOS T mount (DSLR ready)
-Parts alone worth over twice the asking price.

Reason for selling - superseded by larger 8" newtonian astrograph so it is surplus to needs.
