[TS225 (John)]

Hi All,
I have just purchased, second-hand, a TSC225 and EM200B mount. The mount is
circa 90's and only has plug for hand controller. Is it possible to replace
the control box with a later model or incorporate a autoguide function into
the control box? The aim is to do long exposure astrophotography.
Any suggestion welcomed.
The scope is in great condition and has more accessories than I can cope
with!
Cheers
John Field
