Re: Spotting scope eye relief
Kowa makes real good spotters with long eye-relief eyepieces which a have enough eye relief that you can wear your glasses, if you get the larger ones around 80mm you can always get another later and put two of them together on a bracket and have one of the best set of big eyes for long range hunting there is, or if your a high-power shooter then you only need one. I don't remember the actual distance of eye-relief, but I looked thru a lot of Kowas with the long eye-relief eyepieces and didn't have to take off my glasses. They have a web site.
I use the Bushnell Spacemasters,two together on a bracket, (20 plus years old) with the 22x Wide Angle eyepieces and the 27x Kowa Wide Angle eyepieces which are great but you have to take your glasses off for greatest advantage.
