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.

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.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.

TGN8: For GEM mounted scopes up to 46" long and 13" diameter, 57" major height - LXD55/75 SN10, SN8 with Dew Shield 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. There are so many specialty accessories in the astronomy space that are completely unnecessary (I’m looking at you, “telescope gloves”) and we generally tell you to save your money and spend it on gear that is truly going to make a difference on your viewing experience, but that’s not the case here. Safety equipment does matter and is going to save you money long-term by increasing the longevity of your device. Telescope covers vs Bags 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 sewn-in elastic band fits perfectly over the end of your telescope tube, preventing dust from settling on your optics and degrading image quality.

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. 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.
