Opticron Aspheric WA 8×40 Binoculars Review

Evey now and again a pair of binoculars will come along, and no matter how hard you try, you can not find a fault. The Opticron Aspheric WA 8×40 binoculars come in this category.

They come packaged in a quality hard case. First impressions of the binoculars is the build quality. They feel very solid. All the controls are silky smooth without feeling loose. The twist eye cups are of a very high quality. The eye relief seems longer than the stats suggest. Although I found when not wearing glasses, the best setting for the twist cups was around a quarter way out.

Handling is superb. Not the lightest in class, but this is mainly due to the build quality. As the W/A suggests that you get a picture window wide view. This is very true. The flat field gives a bright and crisp image across the whole panorama. Colours and contrast are well on par with many roof prism 8x42s costing £150.

Although they will not focus as close as many modern roof prisms, they are excellent for bird watchers and general use. The wide field of view, good depth of field, long eye relief and easy handling makes them very user friendly

Recently these binoculars won a best in class award for 8×40 binoculars for astronomy. I used these to look at the Moon. Apart from a little reflection (ghosting) they gave a superb view. The craters were easily visible, and all this while hand holding. The Moons of Jupter were easily seen. I can imagine these will give superb wide field views of rich star fields from dark skies.

At £89.00 the Optcron WA 8×40 represent excellent value for money. As already mentioned, I could not find any faults. OK the eyepiece covers were a little tight to remove at first, buy hey, that,s really scrapping the barrel to find something wrong.

Top class binoculars, that wont disappoint

Hawke Premier 8×42 Binoculars. Customers review

 

A customer recently came to the Northern Optics retail outlet looking for a good quality pair of binoculars. Key requirements were to be compact and lightweight.

Despite looking at smaller 8×25 binoculars, they opted for the Hawke Optics Premier 8×42.  From the customers point of view they ticked all the required boxes. Lightweight, compact, great handling, superb optics and could easily fit in a jacket pocket.

The fact they cost only £65 was a surpise and added bonus

North Lincs Astro. Review of Celestron Ultima 80mm spotting scope

At the North Lincolnshire Astronomy Society on the 5th December 2011, we had the chance to test a members Celestron Ultima 20-60×80/45 spotting scope on some astronomical targets.

We were not disappointed. At 60x Jupiter showed the main cloud belts clearly. There was no false colour evident. The image was steady, and the 4 Moons showed up well. This was well on par with many dedicated astronomical scopes of a similar size.

The Orion Nebula was the biggest surprise. Again at 60x the shape of M42 was very bright and clear at 60x. This despite a bright Moon nearby.  Averted vision was needed to get the best out of this target, but was by no means faint when looking direct.

Summing up. It is now quite clear why this spotting scope won best in class in the BBC Sky at Night Magazine. I was fearing that using at full zoom (60x) we would be let down by a narrow and dim view. How wrong I was. This is a superb all rounder.
