Telescope Myths and Legends:

"Large scopes are more adversely affected by seeing than small ones."

"Large telescopes are more impaired by light pollution than small ones."

"Short-focus Newtonians require much larger secondary mirrors than long-focus models."

"Pyrex telescope mirrors are better than those made from plate glass."

 and there are many others, such a long f/ratio telescopes make better "planetary" telescopes than shorter f/ratio telescopes. This ignores the fact that resolution depends on 2 things and 2 things alone - aperture and optical quality (which includes central obstruction). If you have those 2 things you have a telescope that performs well on both planets and deep sky objects. This is why quality, both optical and mechanical, is so important to us at SDM.
