Odd Problem With AO-X

Hi Colin,

This has been going for a while now. You can get the previous discussion and images posted earlier in the thread.

The mount has regular maintenance. But it's also very old (a Paramount ME), that has never been back to Bisque).

I'm suspecting that there are two issues, one in the AO and one in the mount.

Update:

After doing all sorts of controls, trying to isolate the issue, we have found the following:

1. When using my STX-16803, STX guider and AO, the stars are badly streaked.

2. When I take the AO out of the stack, the stars are elongated, but not badly streaked.

3. When I substituted a different STX-16803, without the AO, the stars are round.

I strongly suspect two issues, in some combination of camera, guider and AO. It seems, surprisingly, that the mount is not to problem.

I would like to return the AO, the STX guider and the camera for examination and repair.

How can we get this done?

Thanks.

Mark
