If ease of use, portability and convenience are high on your requirements, and you like gadgets, then a short focal length refractor of up to 4-inches or catadioptric (Schmidt- or Maksutov-Cassegrain) up to 5-inches on a computerized mount may well fit the bill. Both types of instruments are versatile performers and will show many deep-sky objects and reveal considerable detail on the moon and planets at high magnification.

A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. A fantastic choice for beginner and intermediate astronomers, this telescope features a focal length of 1200mm, which enables you to observe the finer details of various celestial bodies. There are alternatives for a lower price, but for quality, we think this Orion scope still wins.Acquiring your first telescope is such an exciting experience. I know that for a fact because I have been through it more than a decade ago. It is an investment that will allow you to explore the night sky in ways that you have never imagined possible. You may have already read the manufacturer’s instructions on how to set up your new telescope. But let me give you a few practical tips on how to get the best out of your new instrument. Attempts by Niccolò Zucchi and James Gregory and theoretical designs by Bonaventura Cavalieri, Marin Mersenne, and Gregory among others The first telescopes focused light by using pieces of curved, clear glass, called lenses. So why do we use mirrors today? Because mirrors are lighter, and they are easier than lenses to make perfectly smooth. Unless you're a seasoned skywatcher and you can afford to go for the more expensive apochromatic — which corrects for such an effect by using exotic glass for the lenses — this degree of color fringing will not ruin your observing experience to any great extent. If you decide to go for the expensive option, you will be stunned by the views you will get through these excellent telescopes. Be warned, though, you might find that some apochromatics come without a tripod, something that you'll have to buy separately along with any accessories.

Telescope - Wikipedia

The bigger the mirrors or lenses, the more light the telescope can gather. Light is then concentrated by the shape of the optics. That light is what we see when we look into the telescope. 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.

How to Use the Bushnell Telescope 78-9512

If you're serious about stargazing and have the budget for an eye-wateringly expensive telescope, then look no further. If you want an all-in-one, hassle-free system but aren't bothered about it being a 'traditional' telescope, you'll love this. It has an incredibly simple setup and a stunning design, although it does price out many astronomers. 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 Astro Fi 102 telescope uses a Maksutov-Cassegrain design, which means it has a large aperture and a long focal length. This combination provides excellent magnification, making it perfect for observing planets. Additionally, the telescope has a wide field of view, making it well-suited for viewing star clusters and nebulas without having to constantly reposition it.
