Thanks for the comments,
what is the sky like at your end of the globe ?
Same question on you Ian, living at the opposite end of the globe ?
Here in Europe there is too much air pollution and un-natural light, at night, to get any really good sky-viewings.
Your new glasses, with their 10cm front lens must be too heavy to hold steadily for any amount of time. Having just read the pitch of the producer, I found no actual weight mentioned, but there was a reference to 'designed for tripod use' !
When used at the x 10 magnification they must be pretty good for viewing animals etc. in poor-light conditions: 100 -:- 10 is a value of 10.
But when you increase the magnification to x 25 you only have a value of 4 (100 -:- 25 is a value of 4) this is ok for the daylight viewing of animals, but as light fails ... very quickly useless.
If you increase the magnification to x 50, you will need bright sunlight to see much at all, 100 -:- 50 is a value of 2), then again you have more than enough sunshine down under.
It is of course a very different thing viewing a bright star, or the moon, in a black sky. It's all a question of what you want the glasses for.
Regarding the price:
Although the lenses in your glasses are multi coated, I found no mention of the glasses having had the air removed from inside. Air always has moisture in it !
Some glasses advertise 'purged by gas', others 'filled with gas', both will remove the air and so the moisture from inside.
Picking at the words I read purged to mean 'cleaned out - removed', but there is no mention of 'prevention of moisture re-entering the glasses'. Whereas 'gas filled' implies 'locked in' and so 'sealed' and this is very important as it should prevent air-moisture from re-entering the glasses. Of course each of these improvements cost ever more money, but each step will improve the useful longevity of the glasses and that's what you pay for.
If there is air in your glasses and the temperature changes, the air (and or gas) will shrink and expand. In the case of air the moisture will condense on the inside of the lenses. As there is no moisture in the gas used this can not happen. The moisture will of course evaporate again when warmed, but it will leave a thin film of dirt on the lenses INSIDE of the glasses! Every time this happens the layer of dirt gets ever thicker. So it seems to be all a question of 'the quality of the the seals' which must be able to withstand positive and negative pressures. This is why extreme heat and cold risk bursting the seals (expansion and contraction of the gas inside) and so should be avoided !
Bob, maybe this was the problem with your C.Z. glasses.
My glasses have just arrived, outside it is just above zero and as soon as the packet was opened the glasses fogged up - on the outside ! First impression is that they are BIG and weigh 1,2 kg. That said, I find holding them in front of the main-body, on the tube, quite comfortable and well balanced. Comparing them to my old 8 x 20 pocket glasses it's, well, like day and night, there is no comparison, I can now see details, whereas before I could see the animal, I can now look it in the eye ! That's a chicken at 50m and with my eyes, which have not been very good for years, a great improvement. Looking through the scrub and beyond, across the fields, the forest is no longer a dark strip on the horizon, I can see the individual tree-trunks at about 1,500 metres. I'm looking forward to dusk when I shall see just how good they are in the dark.
It has not taken long to notice that I can see the shake in my hands, perhaps the 8 x 56, (lighter, compacter and cheaper) with all of the other features, would have been better as a field glass. That said I do most of my observation from the comfort of home, from my verandah and so I can support my arms on the table if needed.
I used to have a telescope and spent many hours moon gazing, but as ever the pressures of other things to do ... I'm still very much in to using the moon calendar for much of my garden work.
I've mentioned this before but do check out the site 'spaceweather.com' it keeps you up to date on what is happening in outer-space today, a bit like the TV Times for the galaxy and they show a great many stunning pictures which the profi's have managed to take with their special equipment.
I'll post more in due course.
