Thread: Scope for F-Class and a bit of everything else

That makes even less sense.

Yup, the bigger the magnifying glass, the more light passing through, more heat.

A bigger scope tube doesn't mean bigger lenses though. Just more space internally to move so more adjustment is available for any given design.

Yes was my point and also that the lenses focus the light down in the middle of the scope so tube diameter is irrelevant in respect to light transmission.

Yuuurp. I like 30mm tubes as they make better handles for my lanky hands.

Yeah, I think 30mm is where it's at as well. It's a good compromise between weight and elevation adjustment. Also 25mm tubes look stupid with big obj lenses ie 50mm and above.

I always shake me head when I hear some retard say "yeah, I went to a 30/34/35mm tube and now my scope is WAY brighter" idiots!
Unfortunately it happens a lot!
