Nebula Filter H-Alpha 2-inch 7nm Reflector The Explore Scientific S-II nebula

The Explore Scientific S-II nebula filter blocks all other colors (and thus almost all artificial light) and only lets through the emission lines of the ionized sulfur at 672 nm

This set opens up a full range of discovery options by including a 40mm telescope

The 4x30 Adventure Binoculars are ideal for on-the-go exploration

Nebula Filter H-Alpha 2-inch 7nm Reflector The Explore Scientific S-II nebulaIn addition to the turbulence in the air, the brightening of the night sky is the greatest obstacle to observing faint objects beyond the solar system. Street lights and other artificial lighting mean that the sky in human settlements is no longer properly black. As a result, the contrast and thus the perception of the deep sky objects also suffer. Depending on the type of celestial object, however, part of the interfering light can be filtered out,
