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 Refractors 76cm (30") long / 101mm (3-4") wide on Alt/Az or Equatorial Mounts. 76cm / 30" major top line, 81cm / 32" major height.
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.

Effective cover for the UK Weaher 29 July 2023 | Steven
I bought this cover so that I can leave my mount set-up between observing sessions to reduce the amount of time spent polar aligning before observing. So far, due to the British summer, I have been able to use it every day (unusal for astronomy equipment) and can confirm that it does an excellent job of keeping the covered equipment dry. It is quick to put on and take off and comes with an additional draw cord to help further secure it to the equipment.

I've had a much larger cover which I've used for years and has protected my telescope in the garden against all weathers.
New one seems just as robust and well constructed.

Seems very solid.

I bought this cover for my Equinox 80ED Pro setup and it is a great fit. The quality is superb and I am confident it will perform well during winter months. It is light, strong and well insulated.
As I don't have a permanent setup, after a night of observing/photographing, I'm often tempted to leave things out and set up ready for the following night if I'm expecting it to be clear but have always been apprehensive about doing this in case it rains. I feel I can now do this with confidence and everything has actually been left set up and ready to use for 4 consecutive nights now and counting.
I'm so glad I bought this.
