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 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...
Collimating a Newtonian telescope is an important maintenance task that involves aligning the mirrors in the telescope to ensure optimal performance. Here are the general steps to collimate a Newtonian telescope: Make sure your telescope is clean and free of dust. You don't want to mistake dust ...
Focusing my telescope using a Bahtinov mask and the ASIAIR focus tool. Why Focus is Critical for Astrophotography In general, the smaller the stars are in your image, the better. One of the reasons I love apochromaticrefractor telescopes, is their ability to capture colorful, pinpoint stars. ...
Astronomical telescopes, such as the Newtonian telescope (invented by Isaac Newton), use parabolic mirrors to eliminate distortions and improve image accuracy.For simplicity, we can approximate that spherical mirrors behave similarly to parabolic mirrors, determining that the focal length of a spherical ...
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 ...
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 ...
Once you have gained enough familiarity with the constellations and the planets, you should decide whether to buy a telescope. Check out our guide to learn how much a good telescope costs and how to get the best value for your money. If you buy a telescope, you can move on to observing...
