If you have already fallen in love with the night sky and you’re ready to move beyond the absolute entry-level gear, you’ll quickly find yourself in the "sweet spot" of amateur astronomy. This is the €100-€250 range—a place where every extra euro spent translates directly into sharper stars and better contrast. In this category, the Nikon Action EX series consistently appears among the most recommended binoculars for beginners who want serious optical quality without jumping into premium pricing.
Why Better Binoculars Actually Cost More
You might wonder: "Both are 50mm, so why is one €60 and the other €200?" The answer lies in the things you cannot see from the outside—the Prisms and the Coatings.
BAK-4 vs. BK-7 Prisms: The Circle of Light
Cheap binoculars often use BK-7 (Borosilicate) glass. While okay for casual use, they often clip the edges of the light beam, resulting in a squared-off exit pupil and dimmer edges.
The Nikon Action EX uses BAK-4 (Barium Crown) prisms. This is a superior density glass that ensures a perfectly round exit pupil and higher light transmission. On the contrary to BK-7, BAK-4 provides much sharper stars all the way to the edge of your vision and significantly better contrast when spotting faint nebulae.
