I use a GM8 mount for visual observing only and am looking for something that will upgrade its max slew rate capability to something near the 4.5*/sec rate delivered by the Meade LXD55-EC series mounts. I realize that this would probably entail new drive motors and a new controller but am hoping the cost wouldn't be much more than a new LXD55. The Gemini GoTo system reportedly slews at a decent rate as does an aftermarket servo based system I read about; however they are both expensive and I don't need GoTo.
Through using an ETX125, I've found that my observing sessions are much more pleasant and productive if I keep my clumsy mitts off the scope. Certainly the OOPS factor is greatly diminished. The slew rates available with my ETX125EC hand controller (8x, 32x, 180x and 5*/sec) are perfectly adequate for my purposes. The ability to fine-adjust the polar tracking rate on the ETX is icing on the cake.
My GM8 alternately carries a C9.25 and a TV102. Would hate to have to replace such a fine mount with a Chinese mount from Meade....even if it is a bargain.
Does anyone know if such an upgrade exists?
