Some will gripe about the price (more than the camera you're probably using it
on!), but in the scheme of taking pictures through a telescope this expense is
modest.
I've tried the mask thing and the varimagni thing, and while both of these help
they are not quite all the way there.
BTW, there's a great technique for determining the precise infinity focus of a
normal camera lens using a mask over the lens with two holes. If anyone's
interested I'll describe it.
