I would like to replace it > anyway as it is the original version hand controller [ HC= 1.6 and MC=4.6 ] > and the firmware cannot be updated. Celestron tell me I would be better > trying to acquire a replacement version 4 hand controller rather than the Nexstar+ > version as the firmware is more compatible with my older version of scope. > As these hand controllers are only available on the secondhand market I am enquiring if any member has one they would be interested in selling.
