I don't think I'll be splashing out for Swarovski's, although if theres an appreciable difference between better low price and midrange, I might go to lower end ED glass;, I've found 8 x 56mm ED Barr and Strouds on offer at £148 (normally about £220), which seems a lot of bang and versatile glasses for the buck; good low light bins for stargazing without needing a tripod, but maybe a tad bulky for twitching. Their 8 x 42 ED's @ £199 are also compared in optical quality to other makes twice the price, and without the extra bulk of 8 x 56's. Nice macro facility too for those butterflies- they focus down to 6 ft. As manufacturers B & S seem good value and decent quality, which is why they are popular and often 'best budget bins' in reviews, where budget class is defined as £100-£300. Strangely Tasco 10-50 x 25 power zooms At £19.99 don't seem to get a mention, even though they show images of distant galaxies in their ads.
The Fujinons I've got are just about the best astro & observation bins in their class and are something like £800 new, so I was a bit chuffed to get a used pair on Ebay for £170, flipping heavy though at nearly 6 lbs. I often sit on a deck chain staring at the milky way with them (you see thousands of stars in one field), it really takes the breath away and makes you feel very very small and insignificant, we have very good skies here with minimal light pollution. I've a 300mm computer guided Telescope with some top Tele Vue eyepieces- its able to see all the nebulas, galaxys and globular clusters. A Polish pal saw the moon through it and said "Wow! I am coming in for landing!". I replied "Yes, and if you look on the left you can see the Apollo landing site with the footprints, and they show their space boots were made in Poland". He looked again, almost believing me.
As a certain Akita chewed the eyecups off one budget pair of bins I had, I think I'd feel nervous with anything top notch, apart from the fact the same amount as a pair of Leicas would buy my Stihl 880 chainsaw. Having not worked for several weeks with the wound, I'm not feeling flushed with cash either, so cost is a big factor.
