Astro-Research 32in Robotic Telescope
The Astro-Research 32 inch telescope ( 0.81 meter ) can reach an unfiltered limiting magnitude of 22.18 magnitude in a five minute exposure using a SBIG STL-1001E. This capability was confirmed on August 5, 2006 while imaging NEO 2001 PJ9.

Subject: Software Bisque MKS 4000
During this first year of operation not one telephone call or email was sent to Software Bisque regarding setup or operation of the MKS 4000. In the first year the MKS 4000 functioned perfectly on every one of the 21,097 slews. Not a single hic-cup occurred while tracking or slewing using the Telescope Control System. Even if the main computer went down, and it did, the MKS 4000 kept on tracking and told the computer where it was without homing after re-boot. During the first year only one T-point model was ran to increase pointing accuracy. The MKS 4000 functioned so well that we never instituted PEC and never enacted ProTrack.
The MKS 4000 by Software Bisque has been operating for over 4 years without a single failure. Clearly this is a testament to the quality and engineering of this telescope control system. The 1.3m (50 inch) telescope currently uses the same telescope controller.
