First never forget, in physics there are not wonders - the simple lens refracts the gathered light, and so it became also a prism but a prism divides the colours of the spectrum, so this lens will create very disturbing orange and blue, blurry semicircles around the celestial objects (like stars and planets, even Moon), and so you can't set the focus properly, simply because there won't be only one exact focal point of all the divided colours. Today this era became a part of the history, but we have memories of this scope building method, so I can mention some tricks to improve the image of this scopes we call "simple scopes", or "nut-thrasher". This old DIY-community was working as a virtual club in Hungary, when the people were under terror by the communism, and almost nobody had enough money to get normal scopes to observe, but a lot of children and adults wanted to look into Universe instead of their misery. There was an astronomer-teacher guy, Kulin Gyorgy, or simply "Uncle Georgie" for those thousands who got helps and assistance from him to build scopes from cheap and simple parts around the house. NIce work, my parents' generation made scopes like this in my homeland, in Hungary. It's that wonderful black tape that's super easy to tear, doesn't leave marks, and isn't very shiny. Make sure each length of PVC is a bit greater than the focal length of the lens. The smaller diameter PVC fit nicely inside the larger one, and, with a little finessing, the lenses fit in each. I used a meter of 3" diameter pvc and a half meter of 2" pvc (I think). Make sure the larger diameter one also has larger magnification power. I got one out of a handheld magnifying glass (the smaller in size lens) and from a scientific equipment shop. I encourage anyone interested in building a telescope to check out my process and modify it as they see fit! Anyway, let's get started! What you'll need: 1. Sadly, there were several things that could've been done much better with more time. I ended up getting a good amount of magnification and I can see craters on the moon in an urban area (Washington, DC). I'm actually pretty pleased with my build. Naturally, then, I decided to build a refracting telescope for the creative project in a class I'm taking called "Changing Views of the Universe". As of late, I've become very interested in space, stars, galaxies, and the universe.
