Astronomical telescopes are a feat of modern engineering. Even the lower budget models are capable of treating you to the fantastic sights the universe as to offer. Telescopes work by collecting electromagnetic radiation in the form of visible light that has travelled across the universe to reach us. Various techniques have been developed over the hundreds of years these instruments have been around to increase their capabilities and allow us to see further into the universe, and consequently, further back in time. It is important to note that each telescope has particular capabilities largely determined by its size and power. The aperture is one of the most vital aspects of the telescope because it is the diameter of this lens that will impact the eventual image you see. Larger apertures are capable of collecting more light and will therefore allow you to see more distant, fainter objects such as galaxies and clusters so it is always important to consider what you want to see and how much money you have to do it. Typically, the larger and more powerful the aperture, the more you will have to pay for the telescope.
At Sherwoods Photographic, we have a fantastic range from some of the world’s best telescope manufacturers such as Celestron, Meade, Skywatcher and Tal. The refractor is a type of telescope that uses an objective lens and an eyepiece to create its image, but because of the optical equipment required they are often the most expensive to create due to the apertures. They do have their use however since they can form images that have a high degree of contrast which makes them perfect for lunar or planetary observations.
If you are looking to save money when making observations then the reflector telescope is the most cost-effective when talking in terms of apertures. It has the advantage of not introducing any false colourisation to the image that you are trying to view. Since both systems have their own advantages, modern the telescope builds on both methods. The Catadioptric telescope can be identified by its relatively short length physical length while also presenting a long focal length. Exploring what is on offer and understanding what it is you are trying to image will ultimately inform which telescope you ultimately buy.
It is worthwhile remembering that even binoculars can offer a window on the universe. While they may not have the same magnification capabilities as a telescope, they can make up for this with portability. This can allow opportunists sights that other astronomers and observers would never be able to take advantage of without planning ahead first. Travelling through the countryside at night for instance can reveal the majesty of the heavens as the light from cities and lampposts dies away. We have a great range including equipment from Celestron, Helios, Opticron and Ostara. Astronomical equipment like this are very handy and are as affordable as you want. They are also great for beginners who want to observe relatively close objects like the moon.
