The Celestron C14 Telescopes
Two 14-inch reflective telescopes
View a C14 in 360 via Momento360
The Observatory has two permanently mounted C14 telescopes. Each is an optical tube assembly from the CGE 1400 series of Celestron telescopes, installed on a Bisque Paramount ME robotic-capable telescope mount.
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 Schuler (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) | Custom Scientific LRGB; Johnson-Cousins RI filters from Astrodon (response curves); Hα filter from Astrodon (6nm bandwidth). Each 3mm thick, 50mm diameter |
| Spectrograph – C14E | The C14E has the possibility to switch from photometry to spectrometry with an Avantes Starline spectrometer covering the 370-800nm wavelength range. |
| ED80 – C14W | An Explore Scientific ED80 f/6 apochromatic refractor is piggybacked on the C14W, for wide-field imaging. |
