The majority of the time, you’ll want to start with low power (and a long eyepiece focal length, such as 25 mm or 30 mm) in order to get the object within the field of vision of the telescope. When this happens, you might wish to experiment with a slightly higher-power eyepiece (with a shorter focal length, such as 18 mm or 15 mm) to see if the view improves.
- The magnification provided by a combination of an eyepiece’s focal length and the focal length of the telescope with which the eyepiece is used is determined by the combination’s focal lengths. As a result, the first step in selecting eyepieces is to determine what magnifications, or powers, you will be using and what focal lengths would be required to achieve them.

Which eyepiece is best for viewing planets?
Because the focal length of the telescope is 900mm, a 4.5mm eyepiece would be perfect for achieving the highest possible practical magnification with the telescope. One of the most appealing aspects of planetary viewing or imaging is that, since the objects are so bright, it is possible to do it almost everywhere, regardless of the presence of light pollution.
What is a good magnification for a telescope to see planets?
Planetary watchers with years of experience employ 20x to 30x magnification per inch of aperture to view the most planetary detail. Double-star observers can magnify objects up to 50 times per inch (which corresponds to an exit pupil of 12 mm). Beyond that, the vision is hampered by the magnifying power of the telescope and the limits of the human eye.
Which eyepiece is best for viewing stars?
However, when the focal length of a Plössl eyepiece decreases, the eye relief of the eyepiece diminishes, making them less suitable for general usage. This design is most suited for seeing nebulae and star clusters than any other. A 15mm and a 25mm Plössl eyepiece would be excellent additions to your present collection of optical instruments.
What can you see with a 25mm telescope eyepiece?
Extending field (long focal length) telescope eyepieces in the 25mm – 30.9mm range are ideal for viewing big nebulae and open clusters with a longer focal length. They are excellent for viewing enormous objects like as the Orion nebula, the complete lunar disc, vast open clusters, and many other things because of their shorter focal length.
What can you see with a 100mm telescope?
To What Can You Look Forward When Using 100mm Telescopes? (With Illustrations)
- When using a 100mm telescope, the greatest magnitude achieved is 13.6. As a point of comparison, the Moon has a magnitude of -12.74 while Mars has a magnitude of -2.6. The Moon is a celestial body. The Moon appears spectacularly in these telescopes, as do Mars, Venus, Jupiter, Saturn, Neptune, Pluto, and the Dwarf Planets.
- Mercury is also visible with these telescopes.
What magnification do I need to see the rings of Saturn?
If you use even the tiniest telescope at 25x [25 times the magnification], you should be able to see Saturn’s rings. A decent 3-inch scope at 50x [50 times magnification] can reveal them as a distinct structure that is completely isolated from the orb of the planet on all sides.
What can I see with a 700mm focal length telescope?
It is quite easy to observe every planet in the Solar System using a telescope of 70mm aperture. On the Moon, you will be able to get a close look at the surface and easily discern the majority of its distinguishable features and craters. Mars is going to look fantastic.
Which eyepiece is best for viewing the Moon?
A 13mm or 14mm eyepiece would suffice for a medium power eyepiece (about 150X magnification). An eyepiece between 25mm and 30mm in diameter would be suitable for a low power eyepiece (about 75X), which is excellent for finding and centering or seeing very huge and near objects such as the Moon or the Sun.
Are telescope eyepieces universal?
It is possible to use any brand of eyepiece in your telescope, with the exception of a few rare exceptions, provided that the barrel size of the eyepiece matches the barrel size of the focuser. If you’re still not sure, take a measurement of the opening in the focuser of your telescope. These days, the 1.25″ barrel size eyepiece is virtually generally accepted as standard.
Are Skywatcher eyepieces any good?
At 65X magnification, seeing through this eyepiece was a delightful experience, and it significantly added to the “wow factor” of a number of items that were observed. Objects were brought into focus without the need to hunt for them. The view was level and clean, with nice contrast and plenty of eye relief, and the sky was clear. As I looked about, I saw that the edge of the vision was dark and sharp.
Are Plossl eyepieces good?
Despite the fact that they only have four lens elements, Plössl eyepieces are excellent all-around performers, giving clear pictures in the center of the field. Improved edge correction with a short-focus telescope is one of the benefits of spending more money on a short-focus telescope, and advanced eyepiece designs can have as many as eight components.
How good are zoom eyepieces?
You may still require very high and low magnification eyepieces (with short and long focal lengths, respectively), but a zoom may be able to handle everything in between for you because of the way they are designed to operate. On the surface, they appear to be a terrific tool, yet nothing is without flaws.
What can I see with a 90mm telescope?
A 90mm telescope will offer you with a clear view of Saturn and its rings, as well as Uranus, Neptune, and Jupiter, which will be visible with its Great Red Spot. With a 90mm telescope, you can also expect to view stars with a stellar magnitude of 12 or higher.
What can you see with a 90x telescope?
If you are looking at the night sky with a very large (wide) telescope, you can see a great deal (if you are in a dark location), but if you are looking at the night sky with a small telescope, you can see a few interesting things (the Moon, planets, some nebulae and star clusters) but not any relatively faint objects.
What can you see with a 150mm telescope?
Refractors between 150 and 180 mm in diameter, reflectors between 175-200 mm in diameter, and catadioptric telescopes:
- Binary stars with an angular separation of less than one inch, dim stars (up to 14 stellar magnitude), lunar features (2 km in diameter), and other celestial objects On Mars, there are clouds and dust storms
- It is possible to see 6-7 moons of Saturn, as well as the planetary disk of Titan
