Before you go on to read our Skywatcher telescope reviews, we thought that you could use a short guide to help you make the best possible purchase. We explain useful info about magnification, the field of view, as well as give some tips regarding some quality and features which should help you obtain a balance between price, usability, and quality, and ensure that you get the right telescope for your needs.
How much magnification is too much?
Many newcomers to astronomy are desperate to get the highest magnification possible in a telescope. Depending on the telescope’s build and quality of components, this can be achieved, but it won’t be cheap. In order to get huge magnification powers, you need to have a very large aperture, so that you get bright views with lots of details.
You need the latest types of coatings for light and contrast enhancement, and you also need other glass components to be of high quality.
Without these quality components and a large aperture, there isn’t a high resolution to magnify in the first place. However, you don’t need a lot of magnification, especially if you’re a beginner. With a telescope that has a 1200-mm or 47.27-inch focal length and an eyepiece of 10mm (0.3937 inches), you get a good 120x magnification, which is more than enough to study planets in our solar system up to Saturn, as well as to admire distant nebulae and galaxies.
Just so you know, the highest useful magnification for a telescope is usually 50 times its aperture in inches or 2 times the aperture in millimeters. So for a 4-inch aperture, you get to a maximum magnification of 200x.
Any more than that and distant objects will appear fuzzy, with loss of detail and unsharp edges. The quality of components and weather conditions also affect it, as lower quality glass and a hazy atmosphere will lower it.
A bit about field of view
The field of view is also important to consider before buying a telescope. Just in case you forgot, the field of view is influenced by the focal ratio of a telescope, which is its focal length divided by its aperture, as well as the eyepieces you mount. So for a 1200mm (47 inches) telescope with a 254 mm (10-inch) aperture, you get a focal ratio of f/4.7, which provides decent magnification with a wide field of view.
The wider the field of view, the more planets, stars, and galaxies you can see in one go. The narrower the field of view is, the closer objects appear, but you get to see less of the sky. For starters, a telescope with a medium focal length and a small aperture can be a good pick, since you get to explore close objects first in high detail, such as the Moon with its craters, valleys and mountains, Mars, Saturn with its amazing rings and multiple (62) moons, and Jupiter.
Complexity or ease of use?
This one will depend on your level and knowledge. If you are already accustomed to entry-level telescopes, then you can obviously go for a more complex model. However, if you’re just starting out, it would probably be better to spend a smaller amount of money on a simple telescope, learn how to align it, how to focus on distant objects, how to collimate the mirror and so on, and only later go for a more sophisticated telescope.
The more expensive a telescope, the more gadgets, buttons, and knobs appear, and you need to learn how to use them all. All these might seem overwhelming for a beginner, although learning is still possible, it’s just that the learning curve would be much steeper.
Ease of use also translates into convenience. Do you want the best telescope from Skywatcher in terms of quality? Then you’d better be prepared to spend at least half an hour mounting and dismounting it, and you can rest assured that the telescope will be heavy enough to require a car to carry. A lighter telescope is easier to carry around in a backpack and faster to set up for observations but will offer lower quality.
