Celestron CG5-GT

[starscy]

On the mount head next to the mounting platform (in which the dovetail slides) there is an empty hole. Does anyone know what is the purpose of this?

I had a CG5GT, not sure what your talking about, can you post a pic od said hole?

Is this "normal"? Do all CG5-GT mounts have this?

I think the hole is where the non goto dec axis drive motor would have been attached on the standard cg5.

mmmmm, from memory I thought there should have been a screw in there so I went looking on the web for the improvment guide I used when I regreased mine, here's the link..... Deep Sky Eye Observatory If you look at the guide then you will see that it is the slot for the dec drive motor adjustment screw and it therefor should be there.

Unless, Celestron have changed the design slightly since mine was made, but I doubt that.

Hope that helps mate.

Could others check their mounts for this?

Mine is the same as this - it would appear the hole is superfluous as the drive housing below has no penetrations to accept a stud.

Cornelius, I think may have hit it on the head perhaps it is probbaly intended for a different mount version/configuration.

This is standard, were on about the hole on the right aren't we ! This is where the dec axis motor get screwed onto, it's the same as an EQ5 mount. The screw usually get included when you by either a Goto/Dual Motor upgrade.

Why do some CG5-GT (GOTO) mounts have a screw in that hole and some don't? It would be interesting to hear more opinions about this.

[gary1968]

I had the goto version and that is where the dec motor was mounted / adjusted. From the pic above, the mount that starscy has is a goto version as well. I am not sure how the motor is held in place on his mount.

As I said earlier, it might be that Celestron have changed the design but how they are mounting the motor is a mystery.

Having said that, if the mount is working OK starscy then I wouldn't worry about it mate.

The mount seems to be working fine, but I have used it only a few times and for short sessions. Since the mount is quite popular could other users check and report about this?
