Then if you observe the little smudge of light and have a closer look at them you get to see a lot of stars clustered together. The Refractor Telescope is an instrument that uses lenses (objectives) and not a mirror and is attached to the front of the telescope to focus the light rays, in an eyepiece at the bottom of the telescope. If something in the distance catches your eye, just lock the scope in place, replace the eyepiece with something a little stronger and adjust the focus knob for a sharper, clearer image. Celestron: How Do You Determine a Telescope’s Magnification. If you cannot have it in the middle, try to have it as close to the centre as possible.

For that matter, you can use different devices like telescopes and. refractor telescope image by Jim Mills from, Astronomy Hints: Refractor Telescope Tutorial. Your email address will not be published. Loosen the thumbscrew on the telescope’s finder scope mount. Yes! Consult the telescope’s user manual to determine its focal length.

At home is the best place to practice changing the eyepieces and understanding how the mount works. Porch lights, street lights and other sources of light pollution brighten the night sky, making faint objects difficult to observe. Yes! The image may even faint away if you increase the magnification beyond certain limit. Tighten the retaining screw to secure it in place. Aim the telescope at an astronomical target. A Barlow lens doubles or sometimes triples the magnification, keeping the image clear and sharp. Now that you’ve got everything aligned, feel free to explore the cosmos referring to your charts if you get lost. Insert a high-power eyepiece – one with greater than 75X magnification -- into the telescope’s focuser to study the object in greater detail.

Stargazing in the UK is a participant in the Amazon EU Associates Programme, an affiliate advertising programme designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.co.uk. Since it will be dark outside, it’s important to familiarise yourself with the charts in advance instead of trying to refer to them in the dark.

Insert the finder scope into the mount, and tighten the retaining screw. Instead of the usual lenses found in other types, your reflector telescope makes use of large concave mirrors to both gather and focus light. Adjust the focuser to sharpen the object in the eyepiece. Now what is field of view? At this point of time, you will replace your eyepiece. Fortunately, this means that this type of telescope excels at extraterrestrial gazing. Otherwise you will end up having blurred images in case of extra-high magnification. Joel Douglas has been writing professionally since 2004. The telescope used is described on the DIY Refractor Telescope page on this site. As the name suggests, these types of telescopes reflect light through a combination of curved mirrors to form an image. Lucky for you, we’ve put together this here guide to help amateur astronomers learn some tricks and techniques that will turn them into pro backyard stargazers. Due to its good visibility and price range, a reflector telescope is perfect for beginners. As a beginner, you need to start observing the objects with the telescope having the lowest magnification of eyepiece. If it is not there, you need to again use the low magnification eyepiece and try again.
