Is 90 mm good for a telescope?
The Orion Astroview 90mm refractor is an ideal telescope for novice astronomers ready to invest in their first model. There are some shortcomings, but this affordable telescope offers the laser-sharp optics that refractors are known for and is ideal for your first views of the Moon, planets, and stars.
What can I see with a 100mm reflector telescope?
This fits your .
- An ideal entry-level reflector telescope with 100mm parabolic primary mirror optics – no plastic lenses as found in some other telescopes made for beginners.
- See hundreds of craters on the Moon, detail on Jupiter and other planets, even when viewing from relatively bright city locations.
Are reflector telescopes any good?
Reflector telescope offers the best price and performance ratio for visual observation of the night skies from the Moon and the planets to star clusters and deep-sky objects. If you are a beginner, then the best reflector telescope is a safe way to start your stargazing journey.
What can I see with a 70mm telescope?
The colorful bands and belts of Jupiter, as well as its four major moons, and the rings of Saturn are clearly visible in a 70mm telescope. Mars, Venus and Mercury are visible in a small scope as well, but are extremely reluctant to give up any detail because of their overwhelming brightness.
What can you see with a 4.5 inch reflector telescope?
In addition to good views of the moon and all eight planets, a 4.5-inch reflector will show all of the Messier objects and hundreds more galaxies, nebulae and star clusters. That is assuming the skies are moonless, clear and you’re away from urban areas.
Can you see planets with a 90mm telescope?
But as a general statement, in a 90 mm refractor you will see: Mars – polar ice caps, perhaps some shadings on the surface. Saturn – Rings, maybe the Cassini divide in the rings, perhaps some cloud bands on the planet, maybe the moon Titan. Venus – phases of Venus at high mag or with a moon filter.
Can you see Saturn with 90mm telescope?
With telescopes of this aperture size, you’ll be able to see the moon and her craters, as well as some of the bigger planets. Although they won’t be able to see them in the greatest of detail, you can easily see things like the rings of Saturn, as well as most nebulae.
How powerful does a telescope have to be to see the rings of Saturn?
25x
The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times]. A good 3-inch scope at 50x [magnified by 50 times] can show them as a separate structure detached on all sides from the ball of the planet.
Should I buy a reflector or refractor telescope?
If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.
Can you see planets with a reflector telescope?
Though reflectors often perform better viewing galaxies or other deep-sky objects, it’s of sufficient size to view the Moon, Jupiter, Saturn, and more planets with some detail. The telescope has an aperture of 203mm and a focal length of 1500mm, providing a more wide-angle field of view.
What can I See with the Astro Fi 90?
The Astro Fi 90 is a computerized alt-azimuth refractor telescope perfect for terrestrial and celestial viewing on the go. The Astro Fi offers dazzling views of craters on the Moon, the rings of Saturn, the Great Red Spot on Jupiter, the Orion Nebula, the Hercules Globular Cluster and so much more at night.
What can you see with a reflector telescope?
We viewed Saturn’s rings, the Moon’s craters, and Jupiter’s cloud bands. The compact and portable reflector telescope also includes an adjustable, full-height steel tripod, which was ideal for the kids and my taller husband. Also included is an accessory tray to keep all the bits and pieces close at hand.
What are the disadvantages of a Newtonian reflector telescope?
One of the most frequently noted disadvantages attributed to the Newtonian reflector telescope is its need for regular collimation (also know as alignment). However, this supposed disadvantage can be reduced to a minor task if lining up the optical elements is approached logically and methodically.
How big is the Orion reflector telescope in inches?
Weighing in at only 23.5 lbs, we found it was a breeze to take along on the weekend into the country for some serious stargazing. The Orion reflector telescope comes with two eyepieces – a 25mm and a 10mm Sirius Plossl 1.25″. It also includes an EZ Finder II aiming device, eyepiece rack, and Starry Night Software.
