I ordered this adapter the other day to power my Super Space Conqueror's drives. While I had already verified that the drives worked by plugging it into an extension cord, it's an AC drive and the power cord is only a few inches long, thus requiring an inverter for my PowerTank or 300 feet of extension cord (no).

A few minutes ago UPS delivered the adapter. It's a cute little thing the size of a credit card. I plugged it into the SSC and PowerTank and it works perfectly!

 

Now if only it was clear tonight...

 Those AC sync. timing motor draw very little current so they will run fine an DC/AC adapter. If you want to get a fancy, first check the frequency that the unit is making. Your telescope  uses a motor speed and gear ratio that drive your scope at solar rate  ( 1 rev in 1440 minutes) when the motor is powered at 60.0 Hz. The frequency that these unit put out  is usually not exactly that frequency. For visual work it won't matter much but you can usually go inside the unit and adjust it and then set so the frequency is 60.1 Hz . That will drive your scope a bit faster and close to sidereal rate of  1 rev in 1436 minutes.

normally those units put out a square wave.  Some fancier ones put out a modified sine wave.

 For these types of AC sync motors it doesn't make a difference if it is square wave or a sine wave. The inductance in the motor will smooth out the waveform and motor will be happy.
