Spotters
I am looking for a spotting scope. I was wondering if someone could fill me in on what I need to be looking for.
A good spotter sure makes your range sessions a lot more enjoyable. And you can use it for looking at wildlife and some casual stargazing, too.
Look for:
a) fully multicoated lenses
Lens coating increases light transmission and cuts down on reflection. If you look for the reflection of a light fixture in a coated lens, it will look dull and green or dull and purple. Almost all scope makers will claim "coated optics" or "fully coated" or "multicoated". None of those statements is really good enough. Go with a scope that says it's been
fully multicoated for the best results. This gives you better light transmission and brighter images. At least go for "multicoated" as a minimum.
b) good eye relief
Especially if you wear eyeglasses. Look for at least 1.5 inches (38mm). This is the distance your eye is from the eyepiece to get a full view. If you back up beyond the specified eye relief, you get "black out" and an incomplete view.
c) good usable power range
If you're going to be using the scope for no more than 100 yards, 25x to 30x is probably enough. If you're going farther out, look for a top power of 45 to 60x.
d) large objective lens
The larger the objective lens, the brighter and more detailed the image will be. My own scope has an 80mm objective lens and it works real well. You'll sometimes see spotting scopes with 50mm objectives - stay away from these. They'll be too dim under most conditions. There are some decent ones with 65mm objectives. They have the advantage of smaller size for easier portability, but they lose some brightness.
Real good spotters at reasonable prices are:
Celestron Ultima
Konus
Vortex
Bushnell Spacemaster
Burris
You should be able to get one of those for $200 or less.
If you're willing to double that amount:
Nikon Prostaff
Bushnell Elite
Celstron Ultima ED
If money's no object:
Swarovski
Zeiss
Leica
And don't forget to buy a STURDY tripod. You can have the world's best scope, but if it's mounted on a jiggly tripod, you won't see anything clearly.
