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. The length is the mirror box to cage separation (+-
1"). (Shrouds WILL
NOT work on Obsessions of 20" and over).
