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.
