More information on the design and construction of the Observatory and Telescope can also be seen here:- 20 inch Observatory and Telescope documents

The Telescope has been through a number of modifications and changes since it was first built back in 1992.

The main change completed in the summer of 2008 was the replacement of Mel Bartels stepper system with the new Sidereal Technology servo system.

The telescope has been developed out of my old 18 inch telescope:- My old 18 inch Telescope
