Spotting Scope Power??

I've been looking alot into spotting scopes and cant decide what I want, it will mainly be used for backcountry mule deer hunting, Price isnt an issue and I was set on buying a Swarovski 20-60x65 but I've also been considering the Zeiss Dialyt 18-45x65 because it looks like it would be easy to stuff in a pack with its straight body design, both scopes are within a 1/2" on length and are within 2 ounces on weight

My concern is the max 45 power on the Zeiss? Am I going to regret not having 60 power when trying to judge mulies between 700-1200 yards? or will the 45 power be enough?

Or should I not even worry about size and weight and just buy the Swarovski 20-60x80? Is the bigger objective worth packin around another 10-12 ounces??

Do yourself a favor and look at Vortex Razor HD reviews.

I was strongly considering the razor until I decided I wanted a smaller objective, and the I've still been considering one

I've owned Leupold 12-40x60s, Swarovski 20-60x65 and 20-60x80s non HD but I'm loving the Razor HD and the spare cash in my pocket! In my experience all the lighter weight is not so much of a benefit once the wind is blowing. I use a beefy tripod as well. That being said I'm being taxi'ed by horses and not backpacking.

Wish horses could fit in on my list of things to get but im going to have to wait on those, I already have the beefy tripod for my video camera, do you notice a big difference between the 60mm and 80mm scopes you've used??

Re: Spotting Scope Power??

Honestly its not night and day. With either if you use the higher magnification, the exit pupil is smaller and hence less bright. I'd bet you can get more clarity from a Swaro 65mm HD than a standard 80mm and save space and weight to boot. On one elk hunt my guide had a piss poor spotter that any little touch would throw it out of focus and a chihuahua legged tripod that was absolutely frustrating.

Add to that a horse that had a belly ache and would roll over and lay down while I was walking him down steep snowy slopes....on my rifle scabbard!
Somehow I was lucky enough to kill a 307 6x6 on the third day!

think mof it this way: Divide the lense diameter with the power. This gives you the actual light transmission you'll see. Ideally you want a factor of three. An 82mm lense divided by 27x gives you 3.03. The same lense divided by 45x gives you 1.82. Ok, but getting somewhat marginal. Kowa is now selling an 88mm lensed scope that will still only give you 1.95, but still better. A 20x scope with a 60mm lense will give you about 3.0, but with a field of view loss in that matters a lot. I use an 82mm lense with a 27x eyepiece, and that's a very bright scope to look thru. It has all the resolution I ever could use.
