I recently bought a Celestron autoguider. It is supposed to make polar alignment and guiding simple because it is all in one package. The product installation was very easy. The auto guider fits into the starsense bracket. I tried to accomplish polar alignment on several nights to no avail. I followed on…

The Sun, Moon, planets, and all objects in the solar system, as well as nebulae,…
I started out with visual astronomy. I initially struggled with mastering the Starsense auto align feature. The instructions in the manual were less than useless. After several attempts using the hand controller I downloaded the Celestron CPI software. Using SPI requires a cable attached to the hand controller and your pc. It worked perfectly making…
There are three basic types of telescopes. Refractor, Reflector and Catadioptic (the most common of which is the Schmidt-Cassegrain).

Developed in the early 1600s, this is the OTA that was popularized by Galileo Galilei just a few years after the invention of telescope. It has a curved lens in the front that…
First where did my interest in astronomy start. It started when I took an undergraduate course in radio astronomy; I was at the time studying Electrical Engineering. during one of the astronomy lectures I was so mesmerized by the wonder of deep space that I tuned out and tuned back in as the lecture…
