That's because it's hard to find the information. Looking through the
manual (really just a pamphlet):

focal length: 700mm f/9
eye-pieces: SR4mm, H12.5mm, H20mm
Apertu 76mm (3")
3X Barlow lens, 1.5X Erecting lens.

That is similar to one of my early telescopes, except that mine did
not come with a Barlow. *What is the focuser diameter? *Does it have a
removable adapter of some sort?

I have no idea, how do I find that out?

If the focuser drawtube, the part that moves when you are trying to
focus, is more than 1.25 inches in outside diameter, then you -might-
be able to unscrew the part that holds the 0.965 inch eyepieces in
place, and have a focuser which will then accept 1.25-inch
eyepieces. * It is well worth investigating this.

Oh okay, that part has an adjustable screw that can be used to tighten
the eyepiece holders down. Other than that, it can't be increased in
size in any way. However, it does have some screws at its base that
holds it in place against the body of the telescope, and it seems to be
removable after unscrewing.

Is this Newtonian telescope roughly as long as its focal length, in
this case 700 mm or about 27+ inches? Or is it much shorter, perhaps
only about 300-350 mm?
