The achromatic refractor is cheaper than the apochromatic refractor and, combined with its efficiency, is often the type of telescope that novice astronomers go for. Even if you choose the more expensive achromatic, you'll likely get a stubborn degree of purple fringing around some targets. This may seem like a silly step, but it’s actually quite an important one. Indeed, the temperature inside your telescope’s optical assembly tube can be quite different from the temperature outside. This can cause a current of warm air current to go through your telescope tube, a convention effect which happens when the warm air inside your telescope expands and collides with the cooler air outside. This can cause your view to be shaky or distorted. Orion Skyline 6-inch Dobsonian Reflector Telescope:A solid choice for beginner and intermediate astronomers thanks to its high-quality optics and ease of use. ★★★★

Aligning the Skymax 127 is a simple process, but beginners may need some practice to get it just right. We recommend becoming familiar with the telescope before dark by reading the manual from cover to cover. Choose your spot. You'll need to choose your spot carefully, once you've decided what you're looking for and where it will be. It will need to be accessible at night and have a place with solid level ground for your telescope's tripod. [6] X Research source The earliest existing record of a telescope was a 1608 patent submitted to the government in the Netherlands by Middelburg spectacle maker Hans Lipperhey for a refracting telescope. [5] The actual inventor is unknown but word of it spread through Europe. Galileo heard about it and, in 1609, built his own version, and made his telescopic observations of celestial objects. [6] [7]Celestron Omni XLT 102:A great option for intermediate users, it has good quality optics and a sturdy design, although we think the focuser could be better.★★★★ It is much easier to make a large, near-perfect mirror than to make a large, near-perfect lens. Also, since mirrors are one-sided, they are easier than lenses to clean and polish.

You're looking long term:There's no question that this telescope is pricey, but it's one that will last you for decades — it's not called 'The World's Most Beloved Telescope' for nothing.While not as long as the Celestron Inspire 100AZ, the Sky-Watcher Explorer 130 EQ2's long tube length results in f/7 and makes high magnification possible. During our review of the Sky-Watcher Explorer 130 EQ2, using the supplied Barlow lens, we could easily get sharp views of the Jovian System (Jupiter, its rings and moons) and Saturn's rings looked impressive. The refractor comes with a 25mm eyepiece, 1.25-inch star diagonal, heavy-duty stainless steel tripod, accessory tray, spirit level, Starry Night Special Edition software and a 6x30 finderscope. There are two common types of reflector telescope — the Newtonian and the Dobsonian. The way these instruments operate is the same — they both use mirrors to reflect light to create an image of the object you're looking at. This telescope uses an impressive 152mm objective lens which allows plenty of light to pass through and makes night sky targets more visible. The multi-coated optics further enhance your sky-viewing experience, ensuring a clear image of those targets. With a focal length of 1200mm, you can observe the finer details of celestial bodies, such as craters on the moon and features of other planets. The Celestron Omni XLT 102 is aimed at intermediate-level skywatchers, particularly those who have mastered setting circles and know how to use the right ascension and declination coordinates on the supplied high-quality CG-4 German equatorial mount.

Consider the type of telescope. Different telescopes are better for different types of viewing. There are really on three basic telescope types: refractor, reflector and catadioptric. Which one you choose will be based on what you want to observe, where you are, and so on. [1] X Research source

You want to do astrophotography:We thought this scope was as close to perfection as you can get for budding astrophotographers, particularly for a smart telescope. Practice. You'll need to practice setting up your telescope and pointing to the correct part of the sky before you start fiddling around at night. Otherwise it is very easy to lose bits of your telescope and forget how to do something.
