TeleGizmos 365 Series Cover for 8" and 10" Schmidt-Cassegrains on a Large German Equatorial Mount

TeleGizmos 365 Series Cover for 8" and 10" Schmidt-Cassegrains on Large German Equatorial Mounts

If your telescope of choice is a classic 8" or 10" Schmidt-Cassegrain perched on a full-sized German equatorial mount, you know how tempting it is to leave it set up for quick observing sessions. But as any seasoned astronomer will tell you, dew, dust, UV exposure, and sudden rainstorms don’t care how expensive your gear is. That’s where the TeleGizmos 365 Series Cover comes in—offering serious, all-weather protection for your SCT and mount all year long.

Rugged Year-Round Protection

TeleGizmos didn’t slap “365” on the name for fun. These covers are purpose-built for 365-day exposure to sun, rain, wind, snow, and more. The outer layer is made from a durable, UV-stabilized, polyurethane-coated polyester—the kind of material used in industrial tarps and marine-grade fabrics. It shrugs off moisture, sheds dust, and deflects bird bombings with ease.

Inside, the thermal inner liner adds an extra layer of defense, reflecting sunlight and helping regulate temperature under the cover. This radiant barrier helps minimize thermal shock to your optics and electronics while preventing condensation build-up during temperature swings. It’s like a thermal blanket for your telescope—one that can handle the outdoors without flinching.

Designed for GEM-Mounted Mid-Aperture SCTs

This 365 Series model is tailored specifically to fit 8" and 10" Schmidt-Cassegrain optical tubes mounted on full-sized German equatorial mounts—the kind with full counterweight shafts, long legs, and no-nonsense tracking power.

• Fits: 8" and 10" SCTs (such as the Celestron C8, C9.25, or Meade LX90 8/10") on large GEM mounts (like the CGEM, Losmandy G11, CEM60, or EQ6-R)

• Height: Approximately 66"

• Circumference: 140"

• Weight: About 4.5 pounds

The open-bottom design gives you flexibility when covering your scope and mount without wrestling. A drawstring closure around the base allows you to cinch it tight around your tripod or pier, helping to keep critters out and the wind from lifting it. For even more security, bungee cords or small cable locks can be added through the grommets.

Built to Withstand Real Observing Conditions

Whether your scope lives in a backyard observatory, on a patio slab, or in a field with a clear view of the Milky Way, this cover is built to handle it. It's been field-tested in climates ranging from snowy mountaintops to desert heat and proven to endure years of exposure without cracking, tearing, or fading.

You spent good money on your SCT and GEM mount combo—protect it like you mean it.

Observing Tip:

If you're tired of lugging your mount and OTA out every time the weather cooperates, a 365 Series cover can be a real observing game-changer. With your gear always ready to go, you'll catch more impromptu views of Jupiter’s moons, surprise meteor showers, or those brief cloudless gaps that only show up when you’ve already packed everything away.
