The huge astronomy labs all use mirror telescopes. Essentially, mirror use mirrors to obtain the desired magnification, while refractive depend solely on glass to get the magnification. Refractives are generally much bigger, heavier because of all the glass in them. Furthermore, the outermost glass of heavy refractive telescopes tend to sink over time due to the effects of gravity, potentially screwing up the focus and causing a blurry image. Getting good images through your telescope depends on two things: - the telescope itself - the time and location of the place your observing Buy the best telescope you can buy without breaking the bank. Cloudless, moonless nights are ideal. Also move as far as possible from cities or heavily populated locations; light polution will rob many detail from the skies.
