No lens means that dust and dirt may get into the internal components of a reflector telescope. Users should plan to clean the telescope regularly and store it in an appropriate location. ![]() CompoundĬompound, or catadioptric, telescopes combine refractor and reflector telescopes into one highly accurate product. Instead of two mirrors or a mirror and a lens, the compound telescope contains two mirrors and one lens. The path that the light travels through the telescope tube is inverted, but it then reverts to an upright orientation before passing through the eyepiece, which means users can view objects in the sky and on Earth. The increased magnification along the tube helps improve the telescope’s strength and clarity. However, compound telescopes typically cost more than refractor or reflector telescopes. Photo: What to Consider When Choosing the Best Telescopeīefore buying a telescope for stargazing, keep in mind these important shopping considerations to help narrow your choice. How you plan to use your new telescope is an important factor to consider. Live viewing is simply looking through the telescope without worrying about videos or photography almost any telescope works for this purpose.Whether you plan to view live, view live and record, or practice astrophotography, consider the different strengths of the various telescopes and mounts. However, for strengths beyond that of the human eye, adequate magnification requires a minimum 70-millimeter (mm) aperture size. Live viewing and recording is when you look through a telescope and use your phone (or another device) to record your session.If you plan to move your telescope to multiple locations during your stargazing expeditions, you probably should consider its portability as well. ![]() This isn’t a new practice, but it’s much more popular now since almost everyone has a smartphone. Astrophotography, essentially the photography of astronomical objects, began almost 200 years ago in 1840, when the first photograph of an astronomical object was taken.To record, look for a telescope with a smartphone mount, which allows you to mount the phone to the telescope so the video and image aren’t distorted by movement.
