Telegizmos protective cover for long 6" refractors on equatorial mount

Telegizmos protective cover for 6" refractors on equatorial mount

Silver colored telescope cover that has the solar/heat reflectivity of a Mylar film.

This material was developed by NASA as insulation for the space shuttles and is accordingly extremely tear resistant. The covers are NOT suitable for continuous use throughout the year, but only for occasional use, for example at telescope meetings or of course for temporary covering of the telescope at home in the garden or on the terrace.

Question:
Do the protective covers also provide protection in the rain?

Answer from Teleskop-Service:
The protective covers are water-repellent, but moisture can penetrate during heavy rain. The main purpose of the covers is to protect against dust, light moisture and sunlight. If you want to leave the telescope set up for a longer time, for example at a telescope meeting, we recommend three layers:

1. An old linen bed sheet on the telescope, this absorbs the stagnant moisture of the night and prevents condensation.
2. The protective cover, which provides protection from most environmental influences.
3. If the weather is unstable (risk of rain), you should put an additional plastic cover over it to prevent water from entering.

Always fasten the whole thing well, so that everything remains firm in the wind.
