  • Telegizmos Cover for SCT/Mak/RC on EQ Mount

    The Telegizmos Standard Cover provides essential protection for your German Equatorial-mounted telescope during temporary outdoor storage. The TGG1 size is listed for 10"-12" SCTs and Maks, with a 28" top line and 36" major height, while the TGG2 is listed for 14" SCTs, Maks and RCs, with a 39" top line and 60" major height. This cover's proprietary solar radiant barrier material, originally developed for NASA as a spacecraft insulator, reflects sunlight to keep your telescope significantly cooler and ready for faster nighttime cool-down, all backed by a 1-year materials and craftsmanship warranty.

    A Radiant Barrier with Double Lap-Sewn Seams

    The core of the Telegizmos cover is its advanced material: a multi-layer polyethylene with a fully aluminized surface and an embedded fibrous webbing for tear and puncture resistance. It is not Mylar. It functions as a radiant barrier, reflecting solar energy to keep a telescope left in sunlight much cooler, which shortens cool-down time once the sun goes down. The material is waterproof and the seams are double lap sewn for strength, protecting against rain and dew.

    Sizing for GEM-Mounted Scopes: TGG1 (28") vs. TGG2 (39")

    These covers are made for Schmidt-Cassegrains, Maksutovs and Ritchey-Chrétiens on German equatorial mounts, and can fit several other scope sizes. To find the best fit, check your set-up dimensions against the stated cover measurements.

    • TGG1 (10"-12" SCTs and Maks): Features a 28" sloping top line, a 36" major vertical height, a 25" minor height, and a 15" width.
    • TGG2 (14" SCTs, Maks and RCs): Offers a 39" sloping top line, a 60" major vertical height, a 40" minor height, and an 18" width.

    A built-in drawstring lets you fasten the cover securely to your scope.

    Standard vs. 365 Series: Temporary vs. 24/7 Outdoor Use

    It is critical to select the right series for your needs. This Standard Telegizmos cover is designed for temporary outside storage, not more than occasional, short-term exposure. For more than 1 to 2 weeks of continuous outdoor exposure, choose the 365 Series, which pairs an outer acrylic-coated woven polyester layer with an inner solar-material radiant barrier liner and is built for continuous 24/7 exposure.

  • Which Telegizmos cover fits an 11" SCT on a German equatorial mount?

    The TGG1 size is listed for 10"-12" SCTs and Maks on German equatorial mounts. Check your set-up dimensions against the stated TGG1 measurements (28" sloping top line, 36" major height, 25" minor height, 15" width) to confirm.

    Can I leave my telescope outside all year with this Telegizmos Standard cover?

    No. This is a Standard Series cover, intended for temporary outdoor storage only. For continuous exposure longer than 1 to 2 weeks, you must use a TeleGizmos 365 Series cover, which is designed for continuous 24/7 outdoor protection, with a warranty that includes 24/7 exposure.

    How does the Telegizmos material keep my telescope cool?

    The cover uses a multi-layer material with a fully aluminized surface that acts as a radiant barrier. It is highly reflective, sending incoming solar heat away from the telescope. This keeps a scope left in sunlight much cooler and reduces the time needed for it to cool down at night.

    Is the Telegizmos Standard cover fully waterproof?

    Yes, the material itself is waterproof and will protect your equipment from rain and dew. The seams are double lap sewn for strength, and the built-in drawstring fastens the cover securely to your scope.

    Will condensation form under the Telegizmos cover?

    Under certain conditions, such as high humidity and large day-to-night temperature swings, some condensation can still form on your telescope beneath any cover. It is good practice to open the cover and allow your equipment to air out after a dewy night if possible.

    My set-up isn't listed. How do I know if the TGG2 cover will fit?

    These covers can fit several other scope sizes. Check your set-up dimensions and compare them with the stated TGG2 measurements: 39" sloping top line, 60" vertical major height, 40" minor height and 18" width.
