Omegon Solar Filter 138-153 mm

Omegon Solar Filter 138-153 mm allows you to safely observe the sun with your telescope. Designed specifically for Newton reflectors with an outer diameter of 138 to 153 mm, this filter fits securely over the telescope tube thanks to a clever clamping system with multiple attachment points.

The filter uses high-quality solar film that allows only a fraction of sunlight through - just enough to study sunspots, edge darkening and the grain structure of the solar surface. The image appears in a neutral grayish white, which is ideal for recognizing fine details in active solar areas. The film used meets international safety standards (ISO 12312-2), allowing you to look through your telescope with peace of mind.

This model comes with adjustment rings and mounting screws, allowing you to securely mount the filter without risk of slipping. The filter is lightweight, robust and reusable - perfect for both novice and advanced solar observers.
