They not only allow you to increase magnification on nights of good seeing, but decrease magnification when the air is less steady. With our science camera, we can get down to 16th mag in less than 30 second exposures. Professional telescopes include both refracting and reflecting models with precision tracking and other features designed to eliminate optical errors and capture the highest quality images. The Dobsonian telescope consists of a Newtonian reflector optical tube assembly mounted on a very simple alt-azimuth box-style mount with a lazy susan base. "@type": "FAQPage", We do recommend you choose a telescope, however, that has a sturdy, easy to use mount and optics that are big enough to see an array of objects. Maksutov-Cassegrain are great for visual use or planetary imaging, the views will be full of contrast with a darker background sky due to their long focal lengths. B.)
