I dropped the power for a crisper view. Now I'm using the Tele Vue 18mm Radian (that's 217 power). It's definitely brighter and crisper. Shows off some of the field stars.
I wonder how long it takes to cool down this huge tube...
The view is wavering quite a lot.

Dietmar says it takes 1 hour to cool down. If it hasn't been in the Sun.
