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. The design specification of the finderscope is 6 x30, where 6 is the magnification power & 30 is the aperture in millimeters.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. This finderscope has a small magnitude and a wider field of view. The function of a finderscope is to find approximately the location of the object or place where we must be viewed. It is pointed in the same direction as a telescope. It is nothing but a small telescope attached to the main telescope of the body. Finderscopeįinderscope is not an essential but an important part of a telescope. It improves its focal length by just adjusting the knob. Generally, the diameter of the telescope is about 8 inches. Telescopic TubeĪ telescopic tube is the body of any telescope which contains a primary mirror. Magnification Power = Focal Length of Objective lens / Focal Length of Eyepiece lens. In final words, the smaller the focal length higher the magnification power. Generally, the magnification of the telescope can be calculated by the ratio of the focal length of the objective lens to the focal length of the eyepiece lens. The eyepiece comes with different focal lengths. The function of the eyepiece is to magnify the image that we must view. The eyepiece is the part of a telescope by which we can see our specific object. For some handheld telescopes, a tripod is used as structural support. This telescope is highly efficient and very easy to handle. So that it mounts on the robust structures & can move on the horizontal and vertical axis. Structural Support / TripodĪs we know, high-power telescopes are huge and difficult to handle with our hands. The primary curved mirror forms an objective, while the secondary curved mirror is placed at the focus of the first mirror inside the telescope body. These two mirrors are called primary and secondary mirrors. Depending upon design consideration, the shape of the mirror can be plane, parabolic, or hyperbolic. The objective lens is at the front side to focus on the image, and the eyepiece lens is at the backside of the telescope for magnification. The objective lens is convex, while the eyepiece lens is concave in shape. The bigger lens is an objective lens, while the smaller lens is an eyepiece lens. In most refracting telescopes, there are two lenses in which is the objective lens, and the other is the eyepiece lens. The lens is one of the necessary parts of a telescope.
