Product Description

This sloped-top 365 Series cover uses dual layer construction to meet the most demanding 24 hour a day/7 day a week/365 day a year outside exposure coverage needs. It is designed to protect any 3" or 4" refractor with a focal ratio of f/6 and faster on a German equatorial mount or altazimuth mount. The scope can have a tube length of up to 30". Some typical scopes might include the TeleVue NP-101 or Takahashi TSA-102S refractors on a TeleVue Panoramic or Gibraltar altazimuth mount, or on a Celestron CG5 or Advanced Series go-to, Losmandy GM-8, Takahashi EM-11, or Vixen Sphinx go-to mount.

A heavy-duty drawstring sewn into the bottom of the cover cinches tight under the telescope base to hold the cover in place in windy conditions. Two spring clamps with plastic tips are provided for additional custom fitting of the cover around your particular scope model. In addition, a lasso-type bungee cord with an adjustable slide barrel lock is provided for additional securing of the cover at midscope/mount areas.

Review by:
I have this cover on my atlas mount that is permanently mounted in my backyard and it keeps everything dry and clean. I add a small gun safe dehumidifier and the humidity is maintained at under 40-45% even after weeks of rain. One thing i would recommend is getting a size larger than you think as it gives you more flexibility if you leave you scope on your mount permanently. (Posted on 11/18/2018)
