The original version of the SRT included a two-axis mount which consisted of two H-180 horizon-to-horizon mounts that were adapted to provide motion in both azimuth and elevation. Due to a lack of availability of the H180 mounts, the Alpha-Spid AZ/EL motor units were tested and provided as part of the SRT kit. Since then, CASSI Corp. has designed and tested a rugged AZ/EL mount that is now the standard mount provided with the kit. Instructions for the assembly of the three kinds of mounts are provided below.
SRT CASSI Mount Assembly Instructions
Kaul-Tronics Proform H-180 Polar Mount: This mount is no longer available, but was provided with the original SRT systems.
Alfa-Spid: An interim mount that was provided in the period during which Cassi Corp was developing their new mount for the SRT system. A limited number of SRTs carry this mount system.
