There is a condition among astronomers known as aperture fever . Aperture fever is the condition an astronomer gets when he or she wishes they had an even larger telescope aperture. The plain truth is, the larger the telescope's aperture, the further into space you will see. It is also true that the larger one's aperture, the more money one has to give up. It is NOT true that a telescope with a lot of magnification power is better then one without.
Aperture is much more important than magnification power.
Some thoughts here are several factors that will effect how clearly you will see anything through any telescope. But you will never see those beautiful color images found in many books or magazines through an amateur telescope. Most all the images used by the media are taken using very large professional telescope using state of the art photographic systems. The final image is then run through computer imaging software to enhance the final colors and image quality. This does not mean that you still can not experience the thrill of seeing, no matter how dim, an astronomical object using your own eyes.
