Mods, I'm not sure if this is the right forum for this thread, of if it should be in the Equipment forum. Please change as you see fit.
Hi all,
I've recently got my hands onto a lovely original orange tube C8. It, like my C5, run on mains power. The original C8 instruction manual, however, shows an "optional extra" a drive corrector that can vary the Hz supply from the typical 50Hz. To speed up the drive, the frequency is increased (upto 85 Hz), to slow it down, the frequency is dropped (down to 35 Hz).
The pic below shows the Orion AccuTrack, which is essentially the same thing. The Celestron drive corrector also had the Lunar, Solar, Sidereal & Automatic rate selections.

Now, would these gadgets be still available, or do they need to be made from scratch. If they need to be made, can someone guide me on how?
Cheers,
Mental.
