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 ›
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 ›
I really am very very pleased. Another brilliant low cost item from Celestron.
The 20x magnification meant that we recently got splendid views of the moon and Jupiter with them. It was quite amazing that Jupiter's shape and also it's four brightest moons were easily visible. And I have to add that the sky wasn't all that clear at the time either (it was a little bit hazy) so we're really keen to see what they'll do when we start getting proper winter clear skies!
The instrument feels well built and the optics are well aligned.
Be aware though that these binoculars are heavy so you'll need some sort of tripod in order to keep them steady.
We went for 20x80 binoculars after reading about different types for astronomy in "Stargazing with binoculars" (published by Firefly), which we'd bought from Amazon some weeks before. We decided to go for something more powerful than the usual 10x50 binoculars as we wanted to get better views of dimmer objects, the moon and the planets. If you don't want to pay this sort of money though, note that Celestron also do cheaper (and lighter) 15x70 and 25x70 models for around half the price. However, if you want even more light gathering power, there is also a 25x100 model but that is around twice the price of these 20x80 binoculars.
Overall, these binoculars have performed well and we don't regret the purchase.
