Here’s a fixer upper for you. This was Celestrons early attempt at a Go-To system.
The foam in the blow molded case deteriorated and left a residue on the Computers connectors. It could probably be cleaned off a little better but the connections are still tight and electrically sound. The computer still works. I had it set up and running this past June. A switch has been added to the front of the computer to turn on and off the displays back light.
This one slews at a whopping 64X sidereal rate so it takes about 10 minutes to slew from one horizon to another. When the scope is polar aligned the pointing accuracy is good enough to place objects within the field of a 26mm eyepiece on a C8.
Because of the extremely fast (yea right) slew rate the motors use a very large step size. The step size is 6.25 arc seconds. This produces a very pronounced pulse when tracking objects. The pulse is so pronounced that viewing bright objects like the Moon and Planets was no good. Viewing DSO’s however is quite acceptable and the pulse is not noticeable.
Since I use my Super Polaris mount mainly for tracking planets I replaced the drive with a Celestron Drive for a CG-5.
I used the motor housings and mounts for the CG-5 motors so you will need to figure some way to mount the motors. The motor mounting brackets shown in the photo are from the CG-5 motors and will not fit into a Vixen motor housing (without some modification). These motors will drive any 144 tooth gear at the proper rate.
