Celestron 71198 Cometron 7x50 Porro Prism Binoculars, Black

Product Information

Other important factors include ‘feel’, which combines the binoculars’ weight and size with balance, tactility and grip. The exit pupil size is directly related to both the magnification and the size of the objective lenses. Robust body, comfortable around the eyes due to the softer viewing aperture and very clear results with great details.

However, because of the complications of viewing through two eye-pieces at once, in most cases, “ Zoom Binoculars” are not really recommended. However, with a very high powered instrument, you will not be able to see the whole of Taurus and thus you lose your reference point making the Seven Sisters much harder to locate. Each tester had their favourite, often influenced by the shape and size of the binoculars: a bit like shoe size. The Konus Tornado’s lightness and neat dimensions merited praise, although some testers expressed reservations about compass legibility and damping.With impressive light grasp from the 50mm lenses and the ideal 7mm exit pupil these comfortable binoculars are just as at home during the day fror nature watching as they are showing the Moon and beyond at night. Distinguishing between the optical performances of the different binoculars is difficult and subjective. Long-eye relief eyepieces and fold-back rubber eyecups for spectacle wearers provide comfort and practicality.

Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. Marine-3 7x50 binoculars are designed and manufactured to meet the toughest performance criteria demanded by enthusiasts and professional users observing from on-board a vessel or onshore looking out to sea. The female testers praised their light weight and Oksana liked the soft eye shields, but both found the compass light button hard to press.

Excellent casual stargazing for the money These are a really great item, good value for money, easy to hold for extended viewing, decided on these instead of the 10x50s after advice from Harrisons. A 7x magnification binocular is considered the ideal marine or low light binocular, this size would be perfect as a gift when you’re unsure of what the binoculars would be used for. These good-value, rubber-coated binoculars have eye adjustment on both lenses and fold-back eyepieces for spectacle wearers.
