When giant
astronomy binoculars first hit the market in any numbers, we had quite a selection in terms of
astronomy binocular size. Over the years, though, the market has pretty much trimmed down the selection, based, of course on sales. Today,
astronomy binocular sales are overwhelmingly for
20x80 binoculars or for
25x100 binoculars, with a smattering of 10x70 binoculars and 15x70 binoculars. One of the sizes that has pretty much gone by the wayside is in a giant binocular is the 11x80. That makes me a bit sad, since an 11x80 was my first giant binocular and it really opened my eyes, so to speak, as to what a giant binocular could do. From a dark sky site with that old 11x80 binocular, I logged many a faint galaxy and nebula. Of course, my current 10x70 astronomy binocular would no doubt do as well, but I have nothing but fond memories of that 11x80. It held its own against some much more expensive binoculars. Wish I still had it.
