I've had this problem with a Skywatcher 120mm refractor and Antares SWA eyepiece. I've heard that there are low-profile 1.25" adapters that you can use with 2" diagonals to give you more inward travel. I'm still searching for one myself. Also some people say aftermarket focusers (ex. Moonlite) may solve this problem.

What telescope has an eyepiece lens and a mirror?

A reflecting telescope has both an eyepiece lens and a mirror. Light enters the telescope and is reflected off the primary mirror to a secondary mirror, which then directs the light to the eyepiece where it is magnified for viewing.


Can a telescope refract light?

The human eye is a refractor, but the telescope could be either refractor or a reflector.


What telescope uses an eyepiece and an objective lens?

Practically all telescopes which use lenses, normally the refracting type. the Reflector use objective Concave Mirrors, but even these need eyepieces or finder scopes.


Will the celestron powerseeker 70az telescope be able to see a solar eclipse?

You don't need ANY kind of telescope to see the solar eclipse. If you have a telescope, and _IF_ you have a projection eyepiece that will project the Sun's image onto the screen, then you can use it - but the problem with viewing the Sun is more in decreasing the intensity of the image rather than magnifying it.


What are some types of telescopes?

there are two main types, all though there are five in total. the first one is called a refractor telescope, which uses a lense to bend the light into an eyepiece. these tend to fog up in winter time but give accurite pictures. a reflector telescope uses two mirors to reflect the light into the eyepiece. you can make these as big as you want and they dont fog up, but the immage can be distorted if the mirror angle is off by the slightest degree. of the two, i would say that the reflector is better than the refractor.there is a limmit to the size of the refractor.


Can you provide a reflector telescope diagram to help me understand how it works?

A reflector telescope uses mirrors to gather and focus light. The primary mirror at the bottom of the telescope reflects light to a smaller secondary mirror, which then directs the light to the eyepiece for viewing. This design allows for a larger aperture and better image quality compared to refractor telescopes.


Does a eyepiece of a telescope have a lens?

A telescope eyepiece usually has 2 lenses in an astronomical telescope, and it is designed to give a magnified view of the virtual image produced at the focal point of the main lens.


How does a refractor telescope work to magnify distant objects?

Ah, hello friend! Imagine a refractor telescope like a magic wand that uses lenses to bend and focus light coming from distant objects like trees or galaxies. By gathering all that light and bringing it into focus, we magnify the image to make it appear closer to our eyes - just like zooming in to see the fine details on a beautiful little squirrel or bird in the woods. Remember, the true magic is in seeing the beauty and wonder all around us, whether we view it up close or from afar.


How does the refracting telescope work?

A refracting telescope uses a lens to bend or refract light, focusing it to create an image at the eyepiece. The objective lens captures and bends light to form an image at the focal point, which is then magnified by the eyepiece for observation.


Why do telescopes for astronomy not have prisms?

Some telescopes do. These are usually at the eyepiece end of a refractor telescope (i.e. one with the lens at the top and you look through the bottom end. The prism bends the light at right angles so you don't get a stiff neck. The prism makes viewing more comfortable. I use one on my telescope.


Are there any problems in using a Reflector Telescope?

Generally instead of looking along the axis of the telescope as is done with a refractor sighting the object to view is more difficult since you view the eyepiece at right angles to the main axis of the reflector. The main way to overcome this is to make a hole in the centre of the mirror as is done in the Hubble telescope and view the image from behind the mirror. This is called a Cassegrain configuration.


What is the power of the eyepiece?

The magnification, or power, at which a telescope is operating is a function of the focal length of the telescope's main (objective) lens (or primary mirror) and the focal length of the eyepiece employed.
