Well, I've been meaning to do this for a while, based upon my brief experiences with my AP900 with this OTA (TEC 200ED) and long term use of another 1200GTO doing a GREAT JOB of slinging around an 8.75" F12 achromat (which weighs about 15 pounds more with a much longer moment arm).
So, I cheated mount and scope death one more time and did the swap out between my Losmandy Titan and this 1200. The 1200 previously provided good support for a large and heavy Parallax/Zambuto 11" F7.2 Newt before I swapped it out for a Mathis MI-500.
Changing the mount out under the big TEC is always a non-trivial and involved process, especially at age 67, but it went well. Next up tonight will be some stretching and an Aleve.
