    The TROK Telescope has now been sold to Terry and is off to Bulgaria (Autumn 2014). Image below is of the proud new owner next to the TROK. Terry is taking on an amazing project to provide a unique Astronomy and Nature facility that is easy access from the UK airports. This will be an ideal location for the telescope under clear dark skies. It will get used a lot more than here in the UK.
    We all wish Terry luck and hope to get out soon to help him assemble the telescope when the observatory is completed. There are not many places you get to look through such a large telescope under good dark skies.

    This will allow for mirrors to e ground/polished and tested in the same rig without the need for a telescope.
    This will reduce risk and time during transfer of the mirror under test.
    The machine allows for the mirror to be raised in position easily during polishing/figuring by 3 hand wheels under the table
    that are easily accessed. A mirror of this size is very heavy and not easily turned on a carpet base!
    The rig is moved to the test area on wheels and locked into place. The table is unlocked and turned through 90 dgerees with
    the mirror supported on a 3mm steel wire at its centre of gravity. No load is put through the rear of the glass.
    Multiple tests at 5 positions over 360 degrees are taken and averaged to create the final error map for figurining.
