See November 2019 Transit of Mercury across the sun with this filter!

Excellent condition in original box. Purchased as a present - unfortunately it's the wrong size hence the sale!

May accept swap for other astronomy equipment - make me an offer!


A must-have for safely observing the Sun without damaging your eyes - optical glass filter fits snugly over your telescope's aperture to block 99.9% of incoming sunlight


Fits 8" Schmidt-Cassegrain Telescopes (SCT)
