By which you mean, the claims of the amazon stuff is hype. Okay. I am not in the market for cheep stuff. I was comparing the $ 500 and $ 1,400 ranges, actually.
The explanation you cite, How to Focus etc et is a very clear explanation, which I would recommend to anyone, but I already have done all this. Corrective eyepieces, you say? I find the view through the existing binoculars kinda dark, so ... I will talk to my eye doctor guy before I shell out $ 1,400 + HST. Thanx for this, um, focus.
