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. 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. 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. I’d say yes. If you have already invested hundreds or even thousands of dollars into a telescope, spending a small fraction of that to keep it safe is worth the money. The most important thing when looking for a cover is making sure it is going to fit your telescope comfortably.
The advantage of covers against bags is really that you can keep the telescope mounted. This takes out the assembly time, and if a kid is going to be using it, reduces the risk of them dropping or breaking something while setting up the tube. The silver coating you will see in high-quality covers serves two purposes. It reflects UV rays to keep them away from the mirrors, and is thermally stable, meaning it prevents the interior and the telescope from heating up. You don’t want your telescope exposed to too much heat because this weakens the optics glue, messing up the mirror/lens alignment, and it makes it so you have to wait longer for the telescope to acclimate to the weather every time you use it to get proper views. Are telescope covers worth the money? Telescopes that are to be left outside the house or garage permanently ideally should be stored in an observatory building. However, for continuous 24/7/365 outside exposure protection where no observatory building is available, the TeleGizmos Series 365 Series covers are recommended.Orion offers telescopes for every level: Beginner, Intermediate, Advanced, and Expert. From our entry level beginner telescopes for amateur astronomers to our Dobsonian telescopes to our most advanced Cassegrain telescopes and accessories, you can find the best telescope for you. Because we sell direct, we can offer you tremendous value at a great price. Not sure how to choose a telescope? Orion's Telescope Buyer's Guide is a great place to start. The Orion cloak cover all the same features you would expect. Waterproofing, sunlight reflection, thermal stability, etc. But the other covers also have most of those features, so what’s the difference? Since 1975 Orion Telescopes & Binoculars has been offering telescopes for sale direct to customers. Now an employee-owned company, we pride ourselves on an unswerving commitment to best quality products, value and unmatched customer care. Our 100% satisfaction guarantee says it all. The only issue I have with this cover is the price. It is high. But is it worth it? well, I believe that really is up to you. Personally, I would only get it for a very expensive telescope, but if yours cost the same or slightly more than the cover then there are better ways to spend that money.

Because we sell direct, we can offer you tremendous value at a great price. You will also see some more values such as Astigmatism and Coma. Again, these are measured by the interferometer when we take measurements of the optical surface after adjustment. These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. The lower the number, the less of these aberations you will effectively see but with most refractors, you can buy field flatteners which will compensate for the coma anyway. The astigmatisms value is explaining the error between the symmetrical curvature of the lens. Basically, no lens will be perfectly symmetrical, the lower the astigmatism, the more symmetrical the lens surface is. 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. TeleGizmos standard Solar Scope Covers - These are designed for temporary short term telescope protection only. They are not designed to protect a telescope left exposed to the elements outdoors on a 24/7/365 basis. The Standard TeleGizmos covers are intended for periods of outdoor exposure not to exceed one to two months of continuous 24/7 use.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. 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. These covers have been tested in the harshest of environments and have proven to be extremely durable and resistant. A dust cover by Astrozap is a great idea for keeping dust off your RC telescope. The sewn-in elastic band fits perfectly over the end of your telescope tube, preventing dust from settling on your optics and degrading image quality.
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. The advantage of bags and cases is they take less space and reduce the risk of someone or something accidentally pushing it and potentially breaking something. 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.The HABOPET cover also claims to be fully waterproof and UV-reflective. As for waterproof, it does look like it meets expectations, but for the reflectiveness, I have my doubts. The coating seems a bit thin and I found no mention of it being thermally stable anywhere in the specifications so I’m not sure it can keep the telescope cool under sunny weather.
