CGE Switch Position Question
Posted 22 September 2013 - 09:45 PM
I would appreciate any help I can get.

I would then have to do that every time I set it up. I don't know where that function for the side by side would be on the hand controller. I looked but couldn't find it.

Before the new function became available some folks who didn't want to use the dec offset for whatever reason would buy an offset plate from ADM. They no longer list it (no need) but could surely make you one.

Edit: if your scopes are pointing to china, its because you want the lock knobs on the mount saddle to be on the right side of the scope, as if your standing directly behind it.

In the Atlas, you can set the home position but I'm not sure how to do that with the CGE so that whenever I set up and hit Switch position, this position is at 90 degrees to the original and my scope faces north.

so side by side bar runs across the cge dovetail east/west and his scopes are pointed north, then when he begans alignment and does the first step ie. set switch position, the scopes slews 90* to the east or west ?

I figured out that when I power the mount on, I need to hit "menu", scope set-up, and then choose East or West depending on which direction the scope is facing. But I guess I'll need to do that each time I power up the mount.
No, you won't need to do that each time you power up...the setting is remembered. If you're using the side-by-side setup with the scopes pointed the same way each time wrt the mount's saddle, you will NOT need to redo the setting. I have a CGEM DX and a CGE and they both work exactly correctly between power cycles when set up for s-b-s. Now, if you revert to a non-s-b-s setup, then you WILL have to redo the setting.
For the poster wanting a photo, here's an example. See how the mount's saddle is at 90° to its normal single-telescope orientation? Since the CGE has position switches that assume the telescope is pointing toward the pole when it homes, that's the source of the problem here. The photo shows a CGEM DX which does NOT have homing switches, but since I have a CGE also, which DOES have homing switches, I simply follow the same rules and make the same orientation setting, even though, technically, one doesn't have to. Confusing, isn't it!?

By the way, I have a triad, with two scopes on either side of my ED127. The other problem I had was that the ED127, and the triad bar, would not "fit" onto the CGE saddle because the DEC clutch knobs would get in the way. I talked to Anthony at ADM and he sent me one of those 90 degree adaptor s that have a 1 inch riser so that the plate and scope would clear the knobs. It is, however, still orientated parallel to the CGE saddle so I'll check to see if I can rotate the block 90 degrees. That would be a good solution too, if I am able to make it work.

The function to set the position of the OTAs on a Celestron gem is called OTA Orientation, it's under Scope Setup. This function was put into the the firmware starting with hand controller firmware version gem4.15. As Dave said it's a "persistent" function, it won't change on power up.
Khavar, Because of your need for extra clearance as well as 90° rotation the ADM solution is best one around. If you ever simplify your setup and no longer need the clearance the firmware function will save you some extra weight.
Depending on which HC firmware you have you'll need different manuals to reference all the HC functions. The CGEPro manual would match the latest firmware available.
www.nexstarsite.com for firmware, connectivity info and manuals.
CGE_Telescope uncensored Yahoo Group is also a great source of reference information on CGE mounts.

At that time, I cured it with the ADM adapter John mentioned. It's a good thing that Celestron fixed that problem.

By the way, that adaptor is heavy. With the adaptor, my traid bar, two V-style saddles, and a large D-style saddle in the middle, the total weight is 13.4 lbs. With the heavy ED127 and the two smaller scopes, that really adds up. And thats without any imaging equipment. I might have to simplify soon.
