Thanks, Jimmy and Captain. I think both of the pieces you guys are using are terrific in optics.
I surfed the Internet about Swarovski's and this article must pop up frontmost each time among the search: http://www.alula.fi/gb/swarovskiATS80HDGB.htm, which said that Swar is just wonderful compared to other fieldscopes of the same class.
A friend of mind who endeavors in birding for years also rated Swar ATS80 highly and said that nowadays, most of the local digiscoping fans are in favor of it than others.
However, how is the situation for Nikon's, which obviously has a good and comprehensive system to support its fieldscopes?
Interestingly, there are not much shots posted that were labelled being taken with Nikon's, for example, the ED82 etc. I think it is good but somewhere somehow, there must be something that falls short of birders' demand that makes it less preferred.
I am not a maniac of gears and absolutely no loyalist of the need for expensive gears for shooting well. What I aim at getting is: money well spent! So, hope you don't mind my asking for comparison.
