100x and above – Like Venus, Mercury also exhibits phases, but you don’t glimpse them until you reach 100x. The higher you go, the phase shape appears bigger in your FOV and is much easier to see, but the planet will still appear white due to its distance. 200x – Detail on the rings are now visible, especially if they are tilted at just the right angle. One such detail is the Cassini Division, which looks like a black stripe on the rings. Another detail is the outline of the planet as the rings go behind it.
This might give you a clue that it is a fabulous all-rounder telescope – which is true (see our full review, here) – but that includes exceling with planetary viewing too. We’ve reviewed five telescopes for seeing planets to match every budget from below $200 to around $1000. If you now but a 6mm eyepiece in the same telescope, you’ll have a magnification of 100x (i.e. 600/6).
Optical Tube – This is the part that most people think of as the telescope. The optical tube has the lens in the front (refractor) or mirror in the back (reflector or Newtonian) that is used to gather light. Neptune can easily be seen with either binoculars or a telescope. You’ll observe a small blue disk that shines at about magnitude 7.7. Neptune’s largest moon, Triton, shines at magnitude 13.5 and is observable with 10-inch or larger telescopes. Watching Jupiter on a nightly basis can bring many spectacular views.
The Pleiades, or Seven Sisters, is a cluster of stars in the constellation Taurus. Look for Orion’s Belt, then follow the stars from left to right. Keep Looking for the best telescope under 200 – Look no further! Take a look at the best telescopes under £200 right here! going, and you’ll get to a bright star called Aldebaran, the brightest in Taurus. If you look through binoculars, you’ll be able to see four of Jupiter’s moons, and it’s easiest to view Jupiter in the Summer months and when Jupiter reaches opposition.

The book is a swift tour through the sun’s physics, structure, origins and evolution and a pointer to some of the questions we have about the sun. Targeted at an audience interested in astrophysics but with no formal knowledge, this book is from astrophysicist and science communicator Neil deGrasse Tyson. He is best known for hosting the new version of “Cosmos”, along with his research at the American Museum of Natural History in New York City. Red Dot Finders normally attach to a telescope by means of an elevated bracket.
I always check the collimation after I set my scope up outside before use, and adjust when necessary. As a tidbit of info, planet means “wanderer” in Greek, so they “wander around the sky.” We often recommend various Dobsonian models because of their benefits, but as you’re finding out, once you’re past the tabletop models, they’re not known for being especially small or light. As such, here are some options for scopes that are a little smaller, which may benefit shoppers who live in tight quarters, or who deal with stairs or meaningful distances when it comes to astronomy. There’s just something so amazing about seeing it with your own eyes. Now that you understand the expectations of what you’ll be able to see, here are some of the most commonly recommended telescopes.
These telescopes are popular in 8 and 10-inch apertures, and can be found as large as 14 inches. Many of the newer models have built-in computers that can locate objects by entering their coordinates onto a keypad. The Schmidt-Cassegrain is a great all-around performer for both planetary and deep-sky observing.
Chanda Prescod-Weinstein’s memoir and discussion of physics takes on the science from a few different points of view. You will see talk about stars and other topics relevant to science here, but you’ll also hear calls about how the community can do better in terms of its representation. Red light doesn’t interfere with the dark adaptation of our eyes, and so you will find that most every amateur astronomer you know will have one hanging around their neck or banging around in their pocket. Unlike standard optical finders, a Red Dot Finder needs a battery to operate, and most of the time, it is included. If your red dot finder doesn’t illuminate, make sure and check that the battery doesn’t have a piece of film or other barrier between the battery and the contact point. This film keeps your battery from running down between the time it leaves the manufacturer and arrives at your home.
If you have a GoTo or an automatic driver for finding night sky objects, simply program the computer to search for Mars and track it as it appears to move across the sky. If you considering astrophotography being able to finely track it is essential. And yes, even this temple of ground-based astronomy is open to visitors only on Saturdays. Every traveler to Chile interested in what’s beyond our home planet should visit—and photograph—the country’s Norte Grande region. It’s a surrealistic world of arid deserts, endless salt flats, colorful lagoons, geothermal activity and imposing volcanoes. East of the harbor town of Antofagasta, the Atacama Desert looks like a Martian landscape.
