Lycra Light Shroud

Our light shrouds offer performance and great looks in one package.  This super stretchy material looks great because it is always conforms to the shape of the telescope.  It will not stretch or fade and the inside is flat black. The shroud keeps stray light out of the optical system and more importantly, keeps body heat from crossing the optical path.  This material also has the characteristic of not becoming dripping wet in severe dew conditions.    (Shrouds WILL NOT work on Obsessions of 20" and over).

Top Dimension: Cage diameter (+-1")

Bottom Dimension: Mirror box side or circumference around trusses at bottom divided by 4 (+-1")

Length: The length is the mirror box to cage separation (+- 1.5").
