The optical specification is 14-inch (356mm) Schmidt-Cassegrain design operating at f/11 (3910mm focal length). Custom-built dewcaps were constructed in-house.
The telescopes have Van Slyke Engineering Omega 2.7" focusers, VSE "Mega-Port Sidewinders", and matching CCD cameras installed. Each camera has 6.3 million 9x9 micron pixels in an array of 3072 x 2048 giving a field of view of 18 x 24 arcmin.

Filters – C14E
(5-position filter wheel)
Johnson-Cousins BVRI filters from
(response curves; and a more
detailed discussion) –
original V filter replaced by a near equivalent from Norman Walker;
Hα filter from Custom Scientific (4.5nm bandwidth, peak transmission 0.90).
Each 4mm thick, 48–50mm diameter.
Filters – C14W
(8-position filter wheel)
Johnson-Cousins RI filters from Astrodon (response curves);
Hα filter from Astrodon (6nm bandwidth).
Each 3mm thick, 50mm diameter
Spectrograph – C14E
||The C14E is equipped, on an experimental basis, with a Shelyak Lhires III spectrograph, with a fibre feed designed and constructed by Nic Clarke. Stephen Boyle's commissioning-phase report is available, characterizing the system prior to the fibre feed (which leaves many properties unaffected).|
ED80 – C14W
||An Explore Scientific ED80 f/6 apochromatic refractor is piggybacked on the C14W, for wide-field imaging.|
