We all know that personal preference is a big factor when choosing a
binocular. These are the things that transcend binocular specifications and, sometimes, they can be the most unlikely of features. When it comes to
astronomy binoculars, for instance, I simply must have a model with leatherette covering. Why? Not because of any superiority of leatherette over rubber armoring. Far from it - rubber armoring makes much more sense than leatherette as a
binocular covering. It's just that the smell of leatherette fondly reminds me of my very first binocular, which I used for both birding and astronomy. The feel and aroma of leatherette also brings back memories of every giant astronomy binocular I have owned, since. Binocular astronomy just would not be the same for me without this relatively minor binocular feature. Go figure.
