Field notes: There is some misconception surrounding the type of prism glass used in binoculars. It is widely assumed that BAK4 prisms are superior to BK7 prism glass and whilst it is true that BAK4 prisms have the advantage of reflecting the entire light cone of low powered porro prism binoculars of focal length f5 or faster BK7 prism glass is still the preferred choice for longer focal length instruments including spotting scopes. This is because BK7 prism glass returns lower levels of spherical aberration, lower levels of chromatic aberration and has lower dispersion than BAK4 prism glass. BK7 prism glass also has a lower bubble count than BAK4 prism glass. The Hilkinson Skyline 15x70 clearly demonstrates the benefit of using slightly oversized good quality BK7 prism glass in its configuration, the image is excellent revealing fine detail with clear contrast and transparency and low aberrations. If you are looking for an affordable high powered astronomy or observation binocular this is the one to buy, it is superior to the generic slightly lower priced models offered by many other brands. The build quality is exceptional. Highly recommended.

The Hilkinson name is a British brand that came to prominence back in the 1950's, producing high quality binoculars made in some of the best Japanese factories. The Hilkinson name still produces binoculars of distinction and quality today.
