I know I won't be getting a professional, top-tier telescope for $300 as those cost way more but for now I’m looking for something simpler. I've received a lot of great advice on potential options and I’ve definitely got plenty to think about. Based on your suggestions, I’ve dec...
The Newtonian reflector was a highly successful design, and remains one of the most popular telescope designs in use today. Newtonian reflectors Rich-field (or wide-field) reflectors are a type of Newtonian reflector with short focal ratios and low magnification. The focal ratio, or f/number,...
I want to start a new telescope project with a DIY 12'' newtonian telescope. If this telescope had a parabolic mirror it would be supercool! So, the first thing I do before I start making something is reasearch. A LOT of reaserch! So I searched here and on other astronomy forums but ...
Learn the definition of a reflecting telescope, Newtonian telescope, and Cassegrain telescope and how each telescope works. Discover who invented the reflecting telescope. Related to this Question How does a refracting telescope work? How does a refracting optical telescope work?
To this day, nearly all astronomical observatories use a variant of the Newtonian telescope. 3. Newton Perfected Coinage Coins being stamped out and weighed to see that they contain the correct amount of metal. Debasement of coinage by clipping was a problem until the introduction of coins wit...

planetSaturnfor the first time. It was a portable tabletopDobsonian telescopewith a large aperture (compared to other telescope designs) and a functional mount designed for manually pointing the telescope. Without this positive first experience, who knows if I would still be enjoying astronomy to ...
Choosing a camera, telescope, and equatorial mount that delivers the results you’re looking for takes time. Avoid the temptation of purchasing the ‘best’ equipment money can buy from the start. First,you need to first learn the night sky– and the basic principles of night sky photography...
The resulting image will be much brighter, sharper and larger than from a pinhole, since the telescope gathers more light, magnifies the image and allows to focus it properly. You might be able to see some solar surface details (such as sunspots) or even silhouettes of the lunar mountains ...
Function: In many reflector telescopes, a secondary mirror redirects the focused light from the primary mirror to a more convenient location where it can be analyzed.Design: The secondary mirror may be convex and placed at various angles depending on the telescope design (e.g., Newtonia...
