yeah, the dew protection.
I very much like that effect. Thanx guys
Marc, the wind is a good point to be aware of.
On that note: does the stability support of the tube walls get reduced or enhanced regarding tube flexture by having the vanes in the middle of the tube?
and also regarding flexture due to the focuser and finder weight in that location in the middle of the tube rather than on the end?
Another aspect I can't quite understand is the 2ndary being closer to the primary should enhance the normal obstruction effect? It's also quite big: 60mm.
I'm not concerned, at all. I'm just curious
