Hi Jase,
No there is no TCC.
You can always get one from RCOS for US$1850. I think its only useful for remote imagers controlling their scope via the internet.
Otherwise I doubt I would use it. I certainly never felt the need for the other rotators etc. I have used a Tak Camera Angle rotator for that.
Base price for a new RCOS 12.5 inch without TCC and other extras is US$19,030 plus about US$650 shipping plus about AUD$2800 GST all up around AUD$25,000 or so, plus a wait of unknown length.
