[The Mekon (John Briggs)]

David, last night I set my EQ6 up with the polar axis approx 4 degrees east of the SCP (could not see sigma oct. in the polar scope).
Did a three star align and pointing was good. Sent scope to Acamar and centered at 100X. After 10 minutes Acamar had moved about 1/2 way to the edge of the field. Later on 39 Eridani at 150X took about 5 mins to move half way from the centre. So this is what can be expected with a rough polar alignment.
In your first post you stated "slowly goes out of camera view" - a camera has much less F.O.V. than an eyepiece, so I think you may need to accurately align if you are using a camera.
