You might be better off dropping $30K on a backside thinned CCD or CMOS camera + filters for a 0.5m telescope; that can get you from 60% quantum efficiency to 90% which is 1.5X improvement in sensitivity. Whether youre a student, a dedicated amateur, or a working astronomer, theres a professional telescope to suit your needs. Have you watched a piece of paper catch fire when light was shined on it through a magnifying glass? An Imaging Newtonian is a fast reflector telescope that is normally optimized for astrophotography or astro-imaging. I can get useful astrometry at 19th mag and photometry at 18th with longer integration. Folks who want to look at the Moon, Saturn and Jupiter occasionally but who are not interested in photography would do perfectly well with a medium-sized refractor on a simple quality alt-azimuth mount, whereas those who want to do photography would require an equatorial mount with either computerization or dual axis motor drive. CAGE Code: 639A3, Quality new & used scientific equipment, in-stock & ready to ship. Beware - even people who do the right thing and use a properly installed solar filter make the mistake of looking through their finder scope to locate the Sun in their eyepiece!

Ritchey Chretins, or RCs for short, utilize a two-mirror design to bring an image into focus, and are therefore categorized as reflector telescopes. An achromatic refractor is designed with two lenses that are therefore only capable of focusing two wavelengths of light, and are usually the most economical. Most Imaging Newtonian telescopes have an f/5 focal ratio or less, and some are not meant for visual use at all but rather, were designed to be dedicated imaging telescopes. 500-meter Aperture Spherical Telescope (FAST) Additional resources. UH 88 website Institute for Astronomy There are several characteristics you will want to pay attention to when buying a telescope, including Aperture: An old adage about choosing the best telescope goes like this: "Buy the biggest telescope you can afford that you can set up by yourself and will use" While there is obviously a bit more to it than that, this is wise advice because it is a fact that the bigger the diameter of the primary optics, the more you will see.

Beginner's telescopes might have apertures between 2 and 8 inches (60 - 200 mm). 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. Discover more objects bright with more precision and in less time! Swap the eyeball at the eyepiece for an even modest but dedicated camera you can go much much deeper with a sub 0.6m scope in very brief 'liveview ' exposures including colour or science if desired. The smaller the f number, the wider the field and more optimized for astrophotography. A finder scope fits on top of the main telescope and is used to help you find and center objects in your eyepiece. .
