Product description
Elliptical secondary flat for Newtonians - diameter minor axis 100 mm - 97 % reflectivity

Newton primaries of ORION Optics UK belong to the best mirrors on the market. Also the secondaries play in the same quality league.

Accuracy

The surface of the secondaries has a roughness of 1/12 wave RMS or better.

The 97 % HILUX coating

A true highlight - you gain substantially more light at the same aperture. Normal mirrors have reflectivities of about 90 %. 10% of the light is lost, while at the Orion mirrors only 3 % are not reflected. The object appears significantly brighter and the exposure times for photography are reduced.
