So I've been playing around with the 24 inch RedDot and like the focal lenth, coverage, etc...

But...the bellows are WAY out there,and no room for close-focusing nearer than say, 40-50 feet at the closest.

Are there lenses that are longer than a 24 inch focal length, but do not require the bellows to be 24 inches away from the GG?

I think that somewhere I'd heard of such a thing, but I can't remember if it was on the internet or in a dream.
