(easy enough to measure the tube diameter and subtract an inch). Try
this link: http://www.opticsplanet.net/bush-ts-785003.html. Is that the
beast you're looking at?
Most Bushnell labeled optics are mediocre, but not awful. The thing at
the front end is a two-part cap: the center part is removable (maybe for
pre-observing cooling?), and the whole thing lifts out as well.
The supplied finder is trash, and should be replaced with a unit-power
finder, or even a clover-leaf sight: much less frustrating and far more
If it comes with a barlow, throw it out.
If it comes with .95" eyepieces, only the lowest-power one is worth
The mount is probably pretty sloppy, and may need some work before it
will hold objects in view. Or you might need to replace it with a
home-made version of the same type of thing built along "mini-dob"
It's potentially a fine scope to use for casual viewing of the moon,
planets, larger star clusters, and wider double-stars. Don't expect
much on deep-sky or high magnification.
