How amateur telescope makers defended America
Monday, June 24, 2024 by Richard Harris
John Mellish, a young farmer from Wisconsin with only a grade-school education, had a passion for observing the stars. At the dawn of the 20th Century, however, a three-inch refractor from Alvan Clark & Sons was priced at $175, which was unaffordable for Mellish. Despite this, his skills and ingenuity led him to build a six-inch Newtonian telescope for just $15, tha...
Removing star spikes with Cuiv the Lazy Geek
Thursday, May 16, 2024 by Richard Harris
Star spikes, also known as diffraction spikes, are lines radiating from bright stars in images taken with Newtonian telescopes. They occur because of diffraction of light around the secondary mirror's support vanes, also known as the spider vanes. Refracting telescopes, which lack any central obstruction, do not suffer from star spikes and generally offer higher ...

Sharpstar 15028HNT Hyperbolic Newtonian Reflector
Thursday, April 25, 2024 by Richard Harris
The SharpStar 15028HNT, also known as the 150 mm f/2.8 Hyperbolic Newtonian Telescope, boasts an impressive f/2.8 focal ratio that promises super wide field images. Its hyperbolic primary mirror, crafted from a glass similar to Pyrex, significantly minimizes spherical aberration, a common challenge in many telescopes. Additionally, the telescope includes a built-in thre...
