The secondary mirror cover can be used to cover the rear side of the secondary mirror. This considerably reduces the cooling of the secondary mirror through radiation exchange with the upper atmosphere which reduces the risk of dew condensation. The cover is designed to allow sufficient space for an additional secondary mirror heater. Connecting cables can be led to the outside via two 4mm wide channels.
Scope of delivery
NOTE: To avoid astigmatism, make sure that the cover does not touch the secondary mirror!
