TTS-300 Mammoth mount with telescope rOTAtor and side mounts.

The TTS-300 Mammoth Mount is installed exactly in the center of the dome. The alt-az movement pattern of the mount is ideal for an observatory used by a large audience. The mount takes up less space than a traditional German Equatorial Mount of similar capacity and the eyepieces and other instruments are always situated in a good observing position. With groups of students in the observatory in complete darkness it is an advantage not having a long counterweight shaft performing a meridian flip.
There are three telescopes mounted on the mounting.
  • At the top is a 250mm truss newtonian. It is installed on a telescope rOTAtor and permanently fitted with a CCD camera for deep sky imaging.
  • On the left side of the mount is installed a 160mm CFF Telescopes APO. This telescope is meant for general visual observations and planetary imaging. A spectroscope is available for this telescope.
  • On the right side of the mount is an Altair Astro 100mm telescope setup for solar observations in H-alpha light.

The mount, cameras and the dome is all controlled from an Eagle Control unit.

Peak2Valley Instruments from Buxton was main supplier of mount and telescopes.

In Autumn 2017 Westminster School in London opened their brand new “Hooke Observatory” in the science building. The facility is setup inside a Pulsar dome installed at the roof top overlooking House of Parliaments, Westminster Abbey and London Eye. An amazing backdrop for an observatory.
