Are you in the market for a new telescope? Kiwi Binoculars sells a wide variety of telescopes, but how do you know which one is best for you and your needs? Read on to find out how to select a telescope!
Types of Telescopes
When shopping for a telescope, it’s important to consider the type of telescope. Here are three of the most common telescope types:
Refractor Telescopes — Invented by Galileo, these models have a lens in front and an eyepiece in the back. Objective lenses with a diameter of 60 to 90mm are common among casual observers.
Reflector Telescopes — Invented by Sir Isaac Newton, these telescopes use mirrors in place of lenses. It’s important to let these sit out in the ambient air prior to use, otherwise you can experience fogging in the mirrors.
Catadioptric Telescopes — This modern type of telescope uses both mirrors and lenses. They’re often used with battery-operated computerized mounts, which help you to find the celestial bodies that you’re seeking.
Apertures and Magnification
A telescope’s power is, in large part, determined by its diameter, also known as an aperture. The larger the aperture, the more light the telescope can take in and this boosts its ability to view objects at a distance.
As a point of reference, a telescope with a 70mm objective lens pulls in approximately 100 times more light than can be taken in by a human’s eye.
The telescope’s magnification ability should also be taken into consideration. A 140x magnification is fairly commonplace. Magnifications that are beyond this range can sometimes result in a difficult-to-view image that may appear to be “fuzzy” without stabilization.
Comfort and Stability
When purchasing a telescope, it’s important to consider comfort and stability. A shaky telescope — which is more commonplace in cases of extremely high magnification — can result in eye strain and headaches, particularly when you use it for an extended period of time.
For this reason, a tripod is strongly recommended for your telescope to ensure optimal comfort and clarity. Some models also have a stabilization feature.
Another consideration is the eyepiece. Some models feature a “straight through” view, whereas others have an eyepiece that sits at a 45-degree angle to the length of the telescope. With the latter, you can look down into the telescope, which some find to be more comfortable.
These are just a few tips that will help you select a great telescope, so you can view the heavens or get a closer peek during the daytime. Kiwi Binoculars has a wide range of telescopes that are perfect for an array of different uses. Browse our selection today!
