Hey there! I'm an amateur astronomer and I'm looking at saving $400-600 on a telescope, what do you think would be better, a refractor or reflector? I'm willing to carry it in my car and traveling wherever I can to get good images to observe.
Hi! That’s great that you’re looking in to getting a telescope!
Overall, reflector telescopes are better than refractor telescopes. I have a telescope myself, and its a reflector.
They are made up of mirrors, which is an advantage because mirrors can be as big and thin as you want, which makes them overall lighter and easier to move around. Refractor telescopes have lenses in them, which limits them to the size they can be since you can only make lenses of a certain size.
Placement of the lens/mirror is also imperative when talking about telescopes. In reflector telescopes, the mirror is located at the back of the telescope, so the mirror could be as big as you want and it wont bend the telescope in any way. In refractors on the other hand, the lens is located near the front. If the (objective) lens is too big, it can actually cause the telescope to bend, which is why there is limits on how big you can have the lens.
(In my reflector telescope, the lens is actually at the back behind the secondary mirror)
Of course, the main purpose of a telescope is to take in as much light as possible. So naturally, the bigger the opening at the front, the more light the telescope can take in, increasing the image quality.
That being said, both of the telescopes are great, and I’m pretty sure refractors may be a little cheaper. But keep in mind, even if you get a refractor now, there’s always an opportunity to upgrade to a larger, different kind of telescope if you continue with your observing!
Hope that helped! If not, feel free to clarify anything :)
