Astromania offers this cover in 3 different sizes, 23.8″, 30.1″, and 37.6″. The one linked below is the 30.1″ version that will fit telescopes of up to 1000mm in length and 203mm of aperture that will fit most hobbyist-level telescopes. Still, measure yours just to make sure before buying. For its price, this cover is still fully featured and it even has side zippers in case for some reason you want to use your telescope directly under bad weather. I don’t really like the idea of testing the limits of the cover or your scope under the rain, but if you are more adventurous than me, it’s a useful feature to have. While the cover is durable, don’t expect it to withstand a whole season outdoors. It’s not made for that and that’s just true for all telescope covers. They are not made so you can keep your telescope outside permanently, they are made for indoor use and maybe, just maybe so you can leave them out for a couple of days a year.
The outer polyester cover is the highest quality acrylic coated weave. This American made material offers exceptional resistance to mildew and UV as well as superior strength and abrasion resistance. Less than 1% shrinkage or stretch assures continuous proper fit. The water resistant capabilities of this material are outstanding...tested and shown to not allow moisture penetration from a spray test at 40 PSI, 1/2 inch concentrated stream.
Baader Hyperion and Morpheus Eyepiece Case
A year of strenuous testing in some of the harshest outside environments, including the desert southwest, Florida Keys, Colorado @ 8000 feet and the Texas Hill country has proven the 365 Series to be capable of handling all types of weather on a continuous 24/7, 365 basis.
If you are looking for the most premium cover to protect a telescope worth several hundred or even thousands of dollars, Orion has the solution for you. You can also find a telescope cover for specific telescope builds such as 12-inch Schmidt-Cassegrain telescopes on alt-az mounts , 5- to 6-inch Equatorian Refractors, and 10- to 12-inch f/5 Newtonians on German Equatorial Mounts. Buy a tripod coverto protect the legs of your stand from rust, dust, and UV radiation, or get a Celestron telescope cover to match your Celestron rig. Once the Zygo test report has been completed, the optical alignment is thoroughly tested and tuned to ensure they are spot on before they leave us. For refractor telescopes, the length is going to be very close to the telescope’s focal length so just knowing that will tell you if the cover will fit.The specifications should tell you the maximum length the cover fits and then you only need to match it to the length of the tube of your telescope. At Rother Valley Optics, one thing we pride ourselves on is customer service and quality of our equipment. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. One of the main values to look at when testing a refractor is the Strehl ratio. The higher this number, the higher quality lens you have. At Rother Valley Optics, we will guarantee the highest possible Strehl ratio for your telescope. We will aim to provide 0.95 Strehl or higher on Takahashi, RVO Horizon, William Optics and many more! Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument.
These superior quality telescope covers by Telegizmos are the best covers on the market that you can buy. They are designed for severe weather protection and provide years and years of protection even when left out all the time. Orion's telescope and astrophotography accessories will enhance your telescope enjoyment without breaking the bank. Expand your viewing experience with accessories ranging from moon filters to power-boosting Barlow lenses to advanced computerized telescope mounts. Capture breathtaking photos with our affordable astrophotography cameras. And when you're stargazing, Orion's telescope cases and covers, observing gear, red LED flashlights, astronomy books and star charts will make your observing sessions more convenient, comfortable and meaningful.There are a few different methods to store your telescope besides just covers. There are bags and hard cases that can arguably protect the telescope even better. Some people like using both. They use a cover during the seasons with the best weather so they don’t have to re-assemble the telescope every time, and they use a bag the rest of the year or when they know the rain season is coming and the telescope won’t see much use. The most important thing when looking for a cover is making sure it is going to fit your telescope comfortably. It comes in two sizes, a 39″ (990mm), and a 59″ (1500mm). That is the length of the tube, so make sure to know the dimensions of your device before buying. The price difference is minimal though, so if you have doubts, just go with the bigger model.
Originally developed for NASA as a spacecraft insulator, the aluminized multi-layer polyethylene TeleGizmos standard solar cover material is strong, light, tear and puncture resistant, and much more durable than Mylar. It is even washable. TeleGizmos covers consist of a polyethylene base layer, a reinforcing fiber mesh layer, a layer of pure reflective aluminum, and another layer of clear polyethylene with double lap sewn seams for strength. Each cover has a material strength equal to that of a multi-layer lightweight tarp. The aluminized surface reflects away the sun's energy to keep your scope cooler in the daytime. It is waterproof to keep condensation from building up on your scope at night. It stays flexible at temperatures well below freezing and is unaffected by summer sun and heat. The bag-like scope cover fastens securely to your scope by cinching up the built-in drawstring of the opening at the bottom of the cover.A telescope cover is an essential accessory to keep your valuable optics safe from heat, prolonged sunlight, dew, and unexpected wet weather. OPT gives you a wide range of outdoor telescope cover options for specific builds and more universal needs alike. Choose from trusted brands like Orion, Astrozap, and TeleGizmos. I personally own the Astromania cover as well as a Green Witch one that is also amazing but unfortunately can’t list here because the company no longer exists. While I don’t own the others, I have reviewed them or tested them. The inner liner radiant barrier provides radiant heat protection, effectively protecting your equipment from radiant heat build up. Additionally, as a second inner liner it provides additional protection from water penetration. Other measurements such as the PV and RMS are important too. With these measurements, the lower the number the better as it shows less curvature on the lens. The flatter an optical lens, the better it will perform. The PV rating (Peak To Valley) is a measurement from the highest point (Peak) to the lowest point (Valley). From this we get the RMS (Root, Mean, Square). This is a similar figure to the PV and measured exactly the same way. The RMS is basically an average height difference from the PV so again, the lower the better. As you can see form the example below, we measured an RMS of just 0.027 wave which is a very good value.
