Solomark cut corners in the right areas to keep the price down without sacrificing the thing that matters the most which is the quality of the optics. The points against this telescope are things that are not going to detract away from your viewing experience or that can be easily upgraded. The learning curve might be a bit steep at the beginning as it has more professional features than a basic refractor scope, but stick with it for a few viewing sessions and you’ll get the hang of it. If you are a first-time buyer looking to get into the hobby you will learn a lot with this telescope and will definitely enjoy it. It’s a solid telescope with great optics at an incredible price. ![]() The Solomark Polaris 130EQ is absolutely worth the money. If you just want to skip all the talk and hear if this telescope is a good purchase or not, here’s the deal. We compared it with a borrowed Celestron Astromaster 130EQ which has similar specs and is its direct competition. The latter is the one category where telescopes with smaller apertures don’t have the power to be good at, but a 130mm can handle it much better. We used it for lunar, planetary, and deep space observations. We tested the Polaris 130EQ in 3 different sessions with clear conditions. It is rare to say that a 130mm aperture telescope is the biggest device a brand offers because most brands have scopes way larger than that, but Solomark focuses only on the entry-level and enthusiast market for now. It is difficult for newly established brands to gain market share in the optics and astronomy industry because people tend to stick with the brands they know, but Solomark, which was just started in 2014, has managed to step in and gain some fans thanks to their very reasonable prices while keeping good quality optics. Instead, astrophysicists use special detectors to observe gamma rays and to figure out where they come from in the sky.We have reviewed multiple telescopes from Solomark in the past, but we hadn’t had the chance to check out the biggest and most sophisticated telescope in their lineup, the Polaris 130EQ. They go straight through optics used for other wavelengths, making them impossible to reflect or refract. Gamma rays are the universe’s most energetic form of light. Engineers at NASA’s Goddard and Marshall Space Flight Centers have designed mirrors like these for missions like the X-ray Imaging and Spectroscopy Mission (XRISM) and the Imaging X-ray Polarimetry Explorer (IXPE). Since there’s a lot of empty space in the middle of a single paraboloid, X-ray mirrors incorporate multiple mirrors as nested onion-like shells. This is called a grazing incidence mirror. ![]() To detect them, engineers turn the mirrors on their sides so the X-rays can skip off the surface. X-rays can simply pass through the atoms that make up most telescope mirrors. X-ray mirrors use the slightly angled side of the paraboloid. The Webb mirror, for example, is coated with a thin layer of gold so that it can reflect infrared light. ![]() Telescope mirrors are coated with different materials depending on the color of the light they need to reflect. (Backyard telescopes can also have mirrors, too.)Īn X-ray Mirror Assembly built for the X-ray Imaging and Spectroscopy Mission consists of a primary and secondary mirror, each containing 812 nested foil mirror segments. Large mirrors can be made thinner and lighter than lenses of the same size, which makes reflecting scopes ideal for sending to space. Reflecting telescopesĪ telescope that uses a mirror as its primary optical element is called a reflecting telescope. ![]() The first telescopes, developed in the 1600s, were refractors, as are many backyard telescopes today.īut very large lenses make refracting telescopes large and heavy, which makes them difficult to use in space. Like eyeglasses, the lenses bend, or refract, light passing through them. Refracting telescopesĪ telescope using a lens for its main optical element is called a refracting telescope. The larger a mirror or lens, the more light it collects, and the better its ability to detect fainter objects. The size of the main mirror or lens determines how well a telescope can collect light. Astronomers observe distant cosmic objects using telescopes that employ mirrors and lenses to gather and focus light.
