1.
an optical instrument designed to make distant objects appear nearer, containing an arrangement of lenses, or of curved mirrors and lenses, by which rays of light are collected and focused and the resulting image magnified.
as it is an optical device that does this, but that is way beyond budget as my dream lens Canon 400mm f/2.8L or 600mm f/4L costs A$15000. Putting a DIY 32mm eyepiece adapter ( + diagonal + barlow) makes an excellent visual instrument of such a lens.
A nice 14cm APO refractor, even with Barlow it is f/5.6 resp f/8. And an excellent astrophoto performer.

Skysurfer, i understand your enthusiasm for those lenses but in terms of this tread they are "Out of Scope" so to speak, and of course way over budget anyway. As with the Nikon 400mm f2.8, mentioned by JA earlier.
A separate thread exploring camera lenses only needs someone to start it.
