Resilvering The BIG Mirror

This morning, Rod and Ted of the CADSAS committee dismantled parts of the Alan Young telescope to remove the big 22.5″ primary mirror and the smaller secondary mirror.

The mirrors will be sent to Orion Optics very soon.

Orion will re-coat both mirrors.  We are hopeful their service will greatly improve the mirrors’ reflectance of light and therefore our imaging results.

Although often still referred to as “silvering”, the Orion recoating does not use silver. The modern and widely accepted Hilux coating, uses aluminium in the mirror coating process.

Come and visit in the Autumn when it’s dark again and see the results.
