Question 1

What is the difference between 10x50, 8x42, 10x42 & 10-22x50?

Accepted Answer

The first number is the power of the lens, that is how much it will magnify the image.  The second number represents the diameter of the lens in mm.  They work together to calculate a number called the "exit pupil" or "exit ratio".  Take the lens size and divide it by the power to get this number.  The higher the number, the brighter the image.  For example, 10x50 will give an exit ratio of 5.0, 8x42 would be 5.25, 10x42 would be 4.2.  In my opinion, the exit ratio is more important than the power.  My favorite binoculars are 8x50 (6.25) but I also just bought 10x50 as a gift who is delighted with that configuration.  Stay away from high-power binoculars.  They, for me, are too hard to keep steady due to the high magnification.I hope this helps.-Norm

Question 2

Is it possible to view the rings of Saturn with these binoculars?

Accepted Answer

The best view I've gotten with these was from the upper elevations in the Rocky Mountains in Colorado, while at a remote campsite. 4 Moons of Jupiter were very clearly visible, but for the rings of Saturn, I could only get the impression of a ring with my view. The planet itself was so bright so that details were obscure. Looking at Venus with these was blinding. I cannot remember the phase of the moon on these nights but it was probably close to the new moon.

Question 3

What is the items wight?

Accepted Answer

According to the specs, it's 3.05 or 3.06 pounds. Assume it's 3, since .05 or .06 pounds is about an ounce.

Question 4

Do these have a tripod mount and if so, what kind?

Accepted Answer

I'm looking at the box (I just got it for fathers day today). It has "Tripod adaptable for a stable viewing platform by using the optional tripod adapter". You have to buy that separately. The directions even show how to do it. Amazon has the adapter shown (Nikon Adapter 7650). It's kind of spendy, but from what i've read, it's just a standard 1/4"-20 mount- just about any of those will work. not sure where some of the other answers are getting their info.
