Eyepieces and Focusing (Refractor Telescopes) - My Telescope Series

http://bit.ly/2J4GdhW My Telescope Series: Eyepieces and Focusing (Refractor Telescopes) Directed and Produced by Tommy DeJosia Choosing the proper eyepiece can make your star gazing experience easier and more fun. For both a reflector and a refractor telescope, you should start with a higher focal length eyepiece which is the lower magnification. Lower magnification eyepieces will provide you with a wider field of view. This makes spotting objects easier. Once you have found your target and locked your telescope in place, use your lower focal length eye piece for a closer look. Normally refractor telescopes invert your image. This means your target will look upside down. Your refractor telescope comes with an erecting diagonal or erecting prism. This will make your target right-side-up. This makes terrestrial viewing easier and more intuitive to find astronomical targets. To use a diagonal, simply place in the focuser, tighten the thumbscrew, and then place your eyepiece into the diagonal and tighten the thumbscrew. If your Telescope comes with a Barlow lens, this will increase your magnification. The eyepiece is placed into the Barlow lens. Barlow Lenses should only be used once you have found your target and you want a closer look. http://bit.ly/2HpKfzs CarsonOptical May 19, 2019 at 10:43AM
