The Baader features 2" Click lock Star Diagonal that uses
the proprietary Baader Dielectric mirror coatings. Baader's proprietary
coating process maintains the 1/10 wave mirror surface accuracy after
Coating and eliminates the Achilles Heel, where as the normal
multi-layer coating results in high surface stresses that cause a star
diagonal's mirror to warp as much as 1/2 wave, ruining the figure and
distorting the optical wavefront. Baader's Dielectric coatings deliver
as high as 99% photo-visual reflectivity along with an extremely hard
durable surface. The precision mirror is also oversized, and combines
with the large ID nosepiece to pass the largest image cone possible in a
2"
format. |

Mirror rejects deep UV and IR radiation safe for solar
viewing with all white-light and H-alpha solar filters. The Maxbright
mirror coatings will last lifetimes without losing reflectivity, and may
be cleaned with normal care, without fear of scratches. With an
effortless twist of the rubber knurled ring, the clicklock holder clamps
2" eyepieces securely. The unique action utilizes 3-point clamping which
positively and accurately locks 2" eyepieces without any of the wobbling
and misalignment that can occur with single point clamps. |
