Telescope binoculars, also known as astronomy binoculars, are not your run of the mill binoculars, as they are especially geared for use in astronomy or stargazing. The difference has to deal with magnification and aperture as well as the types of mounts. Aperture is of course the widest opening on a pair of binoculars and it indicates the amount of light rays that will be admitted into the binoculars. This is measured by the diameter of the aperture.Â For instance giant telescope binoculars that have an aperture of 25X100 or larger will regulate how well you will see at night when stargazing. The aperture size is referred to as a 100mm's in the case of 25X100 telescope binoculars. The technical name for this is objective lens diameter.
Magnification is commonly defined as something like 8X or 10X. This means that with the 8X an object will be eight times nearer than what the human eye can see. Also, you may wish to know about the exit pupil factor. The magnification such as the 25X above and the diameter of the objective lens will determine the size of the exit pupil.Â Just divide the objective lens diameter (100) by the magnification (25). In the case above the diameter of the exit pupil, which will determine how much light will be transmitted to your eye when you have a 25X100 results in 4mm which is not very good, as you should purchase a giant telescope binoculars that have at least an exit pupil of over 7mm.
Telescopic binoculars or astronomy binoculars proffer the highest and best of optic choices-a true telescopic presentation but without the unpleasant eye strain or squinting required of a telescope. Also the high-end giant binoculars offer image stabilization which is not possible in hand held binoculars but can be found in those that will be mounted. This way, a strong breeze, for instance, will not make your image jiggle to cause significant discomfort to the user. You should know that image stabilization requires the use of a battery to power it.
Telescope binoculars have two eyepieces, usually made with soft, molded cups for eye comfort.Â Telescope binoculars may come with exchangeable eyepieces depending on the cost. Each eyepiece may come with its own focusing capability. Ordinarily they have a very sleek, modern design. When used with a tripod, they are the excellent telescopic binoculars for stargazing at its best.
Costs for such giant binoculars range from the very affordable Celestron SkyMaster Series, to thousands if you are desirous of the upper, upper best such as the VIXEN BT125A 125mm binocular telescope package with 2 LVW22MM eyepieces, tripod, fork mount 5835P2 which retails for $4,999.99 though, of course, these are not meant for the beginner astronomer. Costs for window-mounted tripods that can be used to mount your binoculars to a window sill or even your car window, begin under $50. Regular tripods start at approximately the same price, but can climb to as high as $500 for a some Swarovski models.
Many telescopic, giant binoculars at an affordable price spectrum can be seen at Telescope Binoculars.

If I knew exactly where you were in Ontario, I might be able to help you find a store closer than Efston. There are a _lot_ of good telescope stores in Ontario (including Efston).
Of the telescopes you've listed, my first choice would be the Sky-Watcher Dob, since it has the largest aperture and the most solid mount. Most of the others are on shaky equatorial mounts, very hard to use, and have pretty small apertures.
To the person who's never heard of Sky-Watcher, they're only the main brand of the world's largest telescope maker, Synta. Synta makes almost all of Orion's scopes, and most of Celestron's, except the high end SCTs. They're even making Celestron's 6" SCTs. The Sky-Watcher brand is well known everywhere in the world except the USA.
