The telescope is a collection of optical systems on a telescope mount.

Mount

The mount provides the mechanical means to point the telescopes to any region of the sky.

It is mounted on a 2 metre hight pier which rests on the bed-rock of the mountain and is physically isolated from the observatory building. The pier is constructed of steel and filled with sand to provide further damping.

The mount is a Paramount ME supplied by Software Bisque. It is a equatorial type mount. This means that the RA axis points to the celestial pole, allowing the imaging systems to track objects without field rotation. The picture below shows the Paramount ME telescope mount with the Galaxy and Constellation cameras.

Telescopes

There are three telescopes on the mount, Constellation, Cluster, and Galaxy.

Constellation

This optical system provides our largest field of view. It is designed to image an area of the sky that is big enough to show individual constellations. It can also be used to image the Milky Way, something that is very difficult to see from the UK.

Field of view Approx 40 degrees square
Camera FLI MaxCam CM2-1 fitted with a E2V CCD47-10. 1k x 1k pixels, each 13um square. Class 1
Filter Wheel FLI CFW-2 Eight position filter wheel

Focus N/A (fixed focus point)
Optical Nikon 16mm f2.8 lens

Cluster

This optical system is large enough to cover many important stellar clusters, and sensitive enough to show background stars in an image of the moon. A typical target for this system would be the Pleiades (also known as M45) or a large globular cluster such as M15.

Field of view Approx 4.3 degrees square
Camera FLI MicroLine fitted with a E2V CCD47-10. 1k x 1k pixels, each 13um square. Class 1
Filter Wheel FLI CFW-2 Eight position filter wheel

Focus N/A (fixed focus point)
Optical Nikon 180mm f2.8 lens

Galaxy

This optical system is a real telescope with a 14 inch aperture. It can be used to image any visible Messier object, many NGC objects, small star fields and planets. It also provides detailed close-up images of the moon.

Field of view Approx 24 arc minutes square
Camera FLI MicroLine fitted with a E2V CCD47-10. 1k x 1k pixels, each 13um square. Class 2
