"Colorblind" Glasses

[harley66]

No experience with color corrective lenses but do have poor vision. What I've taken to doing is using Marine binoculars with a built in compass. I'll note the heading on my stage card along with a "descriptive" arrow as to what direction it is from the firing point and the previous target; long arrow, short, up, down, angle etc.

I had gone so far as to build a scope mounted digital tilt compensated compass but found under match pressure the arrows on my card worked faster. I can look at 2 things at once, bouncing between 3 was a bit much.

Same here, I have poor vision and used bino, 7x50 is obviously the standard. I’ve used loads of different brands but only recently started paying attention to names (now that I finally have to buy my own). I remember the standard Bushnells as being so-so, West Marines were garbage. I’ve used Steiner’s “marine” model and had good build quality and optics.

Well, I found little information on these particular models regarding astronomical use. I see it's not really desired in the bird community because it lacks a short focus. They are more suited to be marine binoculars. I know there's no such thing as autofocus binoculars as some vendors claim them to be, and the truth is your eye is the "autofocus" mechanism behind it
