Top Customer Reviews
If you have other viewing objectives than astronomical objects, or are already familiar with binocular specifications, you may want to stop here or just read the latter part of this review before going on to other postings; otherwise, read-on.
There are two main styles of "true" binoculars. Here, binoculars that do not use prisms such as opera glasses, are not discussed further. Most binoculars use one of two type prisms, either roof prisms or Porro prisms. Roof prisms are more modern and have a straight through appearance, i.e., the binocular cylinders form straight tubes. Porro prism binoculars (named after Ignazio Porro) have a tell-tale right angle bend. These usually are manufactured with two prism on each side of the binoculars, i.e., double Porro prisms. Although considerably larger in size, because of their improved optical qualities Porro prism binoculars, such as the model reviewed here, are preferred over roof prism binoculars for astronomical viewing.
Another important aspect of binoculars is the size of their exit pupil. Younger folks have pupils that can open, dilate, to a maximum size of slightly over 7mm. However, as one gets older the size of this window into the eye reduces. Over the age of thirty most folks have a reduction in their dark adapted pupil size of approximately 1mm every 20 years. The exit pupils for a pair of binoculars should ideally approximate the entry pupil of the observer's eye. Although some studies suggest an even smaller exit pupil size, see below. The size of a binoculars' exit pupil is found by dividing aperture by magnification.Read more ›
I bought these binoculars a month ago and am delighted with them. Here's why:
Firstly, you're paying a very low price for a very good piece of equipment. Just as good during daytime use, these are becoming the standard for astronomical viewing and if you're paying hundreds and hundreds for optics of the same magnification then you're a fool. Celestron now pretty much has the market covered in terms of good optics at a knock-down price. These are the binos I see at just about every astronomy gathering I attend. People love them.
Secondly, they're not heavy to transport at all... unless you're five years old or generally given to moaning. I regularly trek out with these plus the Hama tripod on my back without any problems whatsoever. Granted, the bag is not thick enough but with a little bit of common sense you can pad it out with cheap foam lining as I did.
Thirdly, I cannot tell you how many times I've knocked these things against a wall or chair and found they're in perfect order; they're solid, reliable, and pleasant to hold.
My tips would be these:
1) Buy the tripod with them (it'll be down in the "Others bought these with it" thing lower down the page), you'll need it for steady viewing.
2) Don't bother with the 25x100 version unless you're going to buy an expensive liquid head tripod.
3) Do NOT be tempted to use anything other than a special optics cloth to wipe the lenses.
4) If you're going to be out in the garden at night a lot don't forget to leave these outside to cool down for quite some time prior - if you don't, they'll gather condensation on a cold night just like any piece of optical equipment.Read more ›
Six months later and I’ve decided to upgrade to these 25x70 beasts. I was tempted to go for the 25x100 but didn’t want to make the mistake of trying to run before I could walk. I ordered them Friday afternoon and took delivery the following morning. I could barely contain my excitement in opening the box!
The packaging itself is basic, but not too complicated. I had the binoculars, the carry bag (with strap), a wipe-cloth, neck strap, standard instructions and – the most important – a tripod mount. I haven’t bought a tripod yet but may well be making a purchase this week, as these bins aren’t exactly heavy but it’s difficult to maintain a steady focus on, say, the Moon (which by the way looks BEAUTIFUL through these).
So far – and I’m only two days into using them – I’m very, very impressed. Thankfully it was a clear night last night and where I live (Wales, UK) I was able to see the Moon, Venus, Jupiter and its moons, and Saturn! Although the latter was a mere blemish in my lens, I could clearly make out its rings (the planet is almost an oval-shape) and I couldn’t believe my eyes.
The build quality is superb. They feel heavy, but they’re not that heavy if you know what I mean. Of course, buying a tripod will both give you amazing images and give your arms a rest, but for now I’m happy using my garden table as a stabiliser for my elbows.Read more ›
