I would not be looking at re-using the lighting transformer to power your mount, as mention it is designed for a very static load, and you're likely to experience some voltage collapse everytime you slew you mount.


While a bit of an expensive option, i use a Victron Blue smart Battery charger to power my mounts. They have a power supply mode where you can set a static voltage output upto 14vdc.
They also have short circuit detection where they will not output power if it detects a short circuit on the output.
I must be looking at the wrong Stellarmate which had a 230v mains input and 12v output. This unit is capable of powering everything , unless there’s an unkown bit of equipment outside of just the mount and accessories ??
Typically an EQ6-R mount with full 20kg payload tracks at around 0.9 to 1.1 amps @12v and slews around 1.8 to 2.0 amps @12v so there’s adequate spare capacity to run cameras , filter wheel , Focuser , heaters etc..as some of these are cycled loads.
I still don’t understand why he suggesting to use both Stellarmate and the old garden transformer, in addition to mentioning current ratings on both ?

I guess we can wait for a reply
