Query: A fine piece of optics - very clear

These Pentax Binoculars are a very fine piece of optics . They are very clear , smooth in focussing and look/feel very tough.I use them for night sky watching and they work very well for that. I looked up for Comet Holmes and the Binocular once focussed gave a crystal clear view of the night sky--- no fuzzy objects. Some distant star clusters come out really sharp on these binoculars. And it is fog proof and dew proof. I am very satisfied with it.Compare this with a Nikon - I think Pentax will be equal in performance to Nikon. Pentax is little better on price. Till now I had only used Nikon.I only wish that Pentax had been little more generous in giving better lens caps and eye piece covers. These ones are of a very cheap quality especially the one for the eye pieces which is just one whole cover which does not stay in place. Pentax should learn some thing from the Nikon in this matter.
