About this product

Model:  hel_quan7_25x100_30876
Part Number:  30876

The 7.4 is the flagship of the Quantum series of observation binoculars, designed for medium-to-long-range terrestrial and astronomical observations.

Featuring oversized BAK-4 prisms and fully broadband multi-coated optics. Triplet objective lenses offer semi-apochromatic optical performance.

Eyepieces are angled at 45° for convenient terrestrial and astronomical viewing. The eyepieces can also be removed and replaced with many standard 1.25” astronomical eyepieces for added versatility.

Nitrogen-filled (fog-proof) all-metal construction with built-in lens hoods, finderscope shoe and carrying handle. 

The U-Fork mount is specially designed for astronomical use, allowing the binocular to be angled upwards for use at high altitudes approaching the zenith.

Supplied with heavy-duty hardwood tripod and foam-lined storage/carrying case.

Image shows optional finder-scope available separately.

The overall finish of the Quantum-7.4’s seemed to be of a better standard, with all surfaces exuding quality….A hardwood tripod and U-fork mount, which did the job perfectly, made observations at the zenith very comfortable, with the 45° angled view….There wasn’t as much trailing off of image quality towards the edges….Stars really filled the field of view and we felt like we were falling through the sky. This was matched by views of the Moon that were incredibly detailed….Visually the Quantum-7.4’s seemed to have the edge on all the others….The sky background appeared to be the darkest of the four on test, with better contrast, so deep-sky objects like faint nebulae stood out slightly better. Indeed the nebula M17 displayed a mottled surface and was a wonderful smudge in the sky….They were a real delight to use”
