The Schmidt-Casegrain gives the advantages of a long scope while being compact and allows one to view from a more comfortable position. The next logical question is how big should a telescope be. There is NO substitute for aperture, no matter what type scope you buy. The larger the aperture the greater the scope s ability to gather light. This is by far more important than magnification.
Magnification is produced by the eyepiece.
The smaller the value of the eyepiece the greater the magnification. The value of an eyepiece is typically written in the eyepiece tube. Usually eypieces comes in sets of three, with values something like 40mm, 25mm, and 12mm. The 12mm eyepiece would give the greatest magnification. At some point, if one continues to use more powerful eyepieces, the image will start to blur and become fuzzy.
