It's f/6.25, or 100 inches. I use an 8-foot ladder, which is plenty tall for observing at zenith. I haven't measured the scope from ground to tip at vertical, but I don't think it's too much more than the focal length (8 inches maybe? Just a guess). -Rich --- "Gibson, Jim" <gibson@dpg.army.mil> wrote:

I know you have a 16" mirror but what is your focal ratio and when your scopoe is vertical, how tall is it?
