What’s the first thing you do when you get a telescope? Some people immediately start looking at the stars and planets. Others head straight for the nearest astronomy book to read up on what they’re seeing. No matter which approach you take, there are some basic things that everyone should know about using an astronomical telescope. Here’s a beginner’s guide to help you get started:
1) The first step is choosing your tool wisely. Telescopes come in all shapes and sizes, so it pays to do your research before buying one or heading out into nature with just any old instrument. You’ll want something durable but lightweight and easy to use, as well as affordable enough so that if anything breaks down (which can happen), it won’t be a big deal. Consumer telescopes come in two main categories: refractors and reflectors. Refractors tend to be cheaper and easier to carry around, while reflectors are typically more expensive but provide much better image quality. It’s important that you get the scope that suits your needs and budget best – don’t just listen to what other people say or assume that one type is superior to the other!
2) Once you have your ideal telescope, it’s time for an inaugural sky-watching session. Before even plugging it in, take a look at how it works first! You’ll want to familiarise yourself with each component of the telescope before actually using it, so check out the eyepiece, focuser (the knob that allows you to adjust the position of the image), finderscope, and everything else. Make sure that all pieces are working properly before spending some time stargazing!
3) The sky is full of shiny little dots – far more than seven, despite popular opinion! You’ll notice that bright stars look bigger or brighter in different telescopes. This is due to magnification – it’s a way for your scope to make objects seem bigger by increasing their apparent size. A beginner telescope with “low powers” (meaning low magnification) will work best for most people when they first start exploring deep space. As you get used to looking at celestial bodies through your telescope, you might want to try out higher magnification later on. Remember not to be discouraged if the stars and planets all look small – that’s normal!
4) The next step is to align your telescope, which will allow you to find deep-sky objects like galaxies and nebula. Some telescopes come with a built-in system for this (called “Go-To”), while others require some simple math to line up properly with the sky. That might sound complicated, but it’s actually not too bad – you simply need to point at two different constellations and use the right decimals according to what kind of telescope you have. From there on out, just sit back and enjoy those beautiful celestial bodies!
5) Before bringing your telescope home, be sure to clean it thoroughly. The dust and dirt that accumulates while you’re using it outside can get in the way of clear viewing, later on, so don’t forget to give your scope a good wipe-down before storing it back in its carrying case or cabinet. Dust off all optical components (eyepieces, mirrors) with soft microfiber cloths or lens cleaners, then apply some lens cleaning solution to each side of the lenses. After that’s done, you’re ready for stargazing!
6) It’s also important to note that even if you take great care of your telescope, not everything is covered under warranty – for example, if your mirror becomes cracked or damaged by something like an impact (accidents can happen!), you’ll have to buy a new one or at least pay for the repairs. Glass is extremely fragile in astronomical telescopes, so it’s important that you handle yours gently and always keep it safe from harm – even if your scope comes with padding on the mirror box!
7) A telescope is an investment for any hobbyist, but especially stargazers – remember not to overlook its safety when packing up to hit the road! Don’t forget things like extra eyepieces (and lenses), along with dust caps to guard against unwanted light interference. Of course, bringing a blanket or something soft to lie down on will help make sure that you’re comfortable during extended viewing sessions. Just be careful not to get too distracted and lose track of time!
As you can see, using an astronomical telescope is a lot more complicated than one would think. It requires proper preparation and knowledge of the different types of telescopes available on the market today to ensure that they will be effective for your needs. We hope this article has been helpful in guiding you through all aspects of how to use an astronomical telescope so that now you are better equipped with the information needed before making any decisions!
