About this product
Part Number: T34D
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 16-18" vertically parked Dobsonians. 292cm / 115" circumference, 228cm / 90" 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.

Used this on an Orion Optics 16" dobsonian for a year outside after a full clean of the scope, kept outdoors in a rural location but on hard standing. After a year with occasional use (10-20 sessions) and otherwise no movement, the telescope is at least not catastrophically damaged but not in great shape. The telescope must be kept parked at an angle, or condensation collects in the cap and falls onto the secondary and then primary - in my case also rusting the secondary adjustment screws and covering the primary in rust. The cover itself has also leaked badly internally. Fabric elements on the scope (dew heater straps) are covered in mildew, as this sits on the ground and permits no ventilation, despite my efforts to prop it up a little. If you're looking for a short-term cover this is fine, but it's not a solution for year-round outside scope storage, sadly.
Sorry to hear you were disappointed with your Telegizmos cover.

We hope that helps :-)

Very nicely made cover, it is quite heavy and can be quite a job to remove from the telescope without upsetting alignment.
