Introduced in 2017 the Helios Stellar II 100mm observational binoculars are the perfect solution for long distance terrestrial, ship spotting and astronomical use. The oversized eyepieces and long eye relief make them ideal for spectacle wearers as much as non spectacle wearers. With 20x100mm and 25×100 variants, there is something for everyone. The 20x gives longer eye relief , wider FOV and larger exit pupil, where the 25x helps bring in distant objects.
BaK-4 prisms and fully multi-coated optics give outstanding clarity, and the waterproofing means you can use in all conditions. Note these weigh 3.6kg so you will need a sturdy tripod. Good news is they come with a tripod connection bar built in.
The new body has a very smooth and attractive look, and comes packaged in a hard case.
