Collimation with meade 12@ LX200 ACF
« on: 21:25:31, 12 October, 2012 »
Hi

using CCD inspector to measure my collimation on my scope. Got it down to 2-3 " when when I slew the scope to a new position it changes to 12-13" . Is this just what to aspect from my meade or am I missing something. Evething is lock down

Thanks

Hello John.

I don't use your software. But. You could be seeing effects of poor seeing?

If your stars look round when in focus. I wouldn't worry to much.

Or maybe the focus changes during slew.

Are you sure it is not just mirror flop?

I used to get this all the time on my old 10" LX200 when slewing from one side to the other - which is why I arranged to fix the mirror in place with some soft clamps after focussing. The mirror in the 12" is even heavier but I thought that particular issue was addressed some time ago by Meade.
