TeleGizmos Warranty

TeleGizmos 365-series covers are warranted for one year from date of delivery including all labor and material. If your cover fails due to either a manufacturing or material defect, TeleGizmos will repair or replace the cover during this warranty period. Proof of purchase required. This warranty is fully transferable but does not include normal wear and tear.

TeleGizmos 365-series are the BEST telescope covers money can buy! 

Suitable for 10-12" f/5 EQ mounted Newtonians. 127cm / 50" top line length (sloping), 127cm / 50" major height (vertical), 51cm / 20" width.

The TeleGizmos 365 series are designed for severe weather protection.

Features an inner layer of aluminised material for radiant heat protection coupled to an outer cover of highly water, UV and mildew-resistant acrylic coated woven polyester. This combination of materials provides years of protection, even when used outside 24/7, 365-days a year. 

The outer material also offers high strength and abrasion resistance with less than 1% shrinkage or stretch. 

Tested in some of the harshest US environments, including the desert southwest, Florida Keys, Colorado @ 8000 feet and the Texas Hill country, the 365 Series has proven itself capable of handling all types of weather.

NOTE: The cover does an excellent job of keeping out the weather but cannot eliminate condensation (the buildup of condensation is sometimes mistaken for a leak). This is true for all telescope covers. So the telescope must be allowed to dry after each use, before applying the cover. If the telescope is used only rarely and/or your area is prone to dew (i.e. in a valley or near a body of water), we recommend you occasionally remove the cover to let the telescope dry. 



  • Multi-layered material for increased protection.
  • Can be used outside for all-weather 24/7, 365-day protection.
  • Highly water resistant acrylic coated woven polyester outer cover.
  • Aluminised inner-layer provides radiant heat protection.
  • Moisture penetration tested at 40 PSI (1/2" concentrated stream).
  • UV and mildew resistant.
  • Can be securely fastened to your scope with built-in draw string.
  • Additional draw string and clips provide extra security around the middle of the cover.

Telegizmo 365 scope cover
11 June 2023  | 

Iíve only used it one night, so far - thatís another story. I found it a bit of an art fitting it; but then it was dark and it was my first time use. Iíve got high hopes for this cover; itís going to be a real blessing not having to always pack everything away at silly Oíclock in the morning! The cover is well made, very robust and of excellent quality. As a precaution against abrasion to the inner surface and to mitigate condensation, I used a large piece of material draped over the scope prior to placing the cover. I also removed the electrical leads and handset as a precaution. Once Iíve used it a few more times Iím sure it will get a lot easier to use. Itís too early to comment on its longevity, but right now Iím mighty impressed with it.

Telegizmos 356 10-12inch eq mounted newtonian

Seems like a sturdy piece of kit. Only had it on during good weather so far.
Due to the height in the parked position (about 2 metres) I need to get inside the cover in order to drop it on (I'm 1.75m).
I've got reasonable confidence in this cover as it's much better than my previous covering, which worked fine, but was not as good quality and was due for replacement.
