Large GEM mounted up to 58" tube length.
For mount/scope combos requiring 60" of vertical cover length as measured from the end of the scope dew shield down to the end of the counter weight shaft with the scope parked parallel to the polar axis.
The TeleGizmos Telescope Cover is a multi-layer, polyethylene material with a fully aluminized surface. The heat reflective ability of the cover is extremely high with a material strength equal to a multi-layer light weight tarp. The material used for Telegizmos Covers was originally developed for NASA as an insulator in spacecraft. It is very strong, light, tear and puncture resistant and is highly superior to Mylar in durability.
The TeleGizmos material performance is unaffected by wind, sun, sub-freezing temperatures or UV. The fully aluminized/poly exterior surface will keep your scope significantly cooler on hot summer days translating into much faster cool down times once the sun sets.
