PS - why does the Gemini control box have a handcontroller telephone-type jack, but the handcontroller box attaches via a sort of computer COM port type connector?

Probably just a carryover. The original Gemini design used the standard hand controller with some internal modifications; that one used the RJ jacks because the jack was alternatively used for an autoguide port with the 492 controllers. Later Gemini units don't have the display on them and rely on the new hand controller (which has the display); they have a separate autoguide port.

John,

Yes, that is most likely. I got this mount to put my Gladius 315 on. Initially I thought I could use an existing EM-200 mount I already had, but the length of the Gladius seemed to make that a bad idea... at least to me... although others said it could be done. Anyway, I'm very glad now that I did get the G11... I wouldn't want anything smaller or less "beefy" for the Gladius after seeing it on the mount. Its not just a question of weight... because the Gladius is a long telescope with a fair amount of weight at the far end. I'm posting a photo of it on the G11 to give you an idea of the size etc. Anyway... just waiting for the power supply to arrive now... then I can finally have 1st light after a year or so of waiting to get everything together...

Rick

Hi,

I do not know if it is a carryover but it comes in quite handy for example if you are using Thomas Hiltons adapter in order to get a second RS232 port on the Gemini (in this case you replace the handpaddle by a PC using GCC)

Then you have the RS232 port on the gemini into which you connect your pC and use this port for driving the Gmeini with your planetarium program and then you can still plug in a handcontrol into the handcontrol marked port of the Gwemini and drive your Gemini GoTo unit manually. Nice, is it not ?

By the way, the encoders of the Gemini are at the end of the servo motors inside the Aluminum housing
