No they cannot be removed. The mirror would need to be recoated, which is too expensive for your scope.

However, tiny scratches probably will not affect your view through the telescope. (maybe)

Need to know how to use the telescope after it is setup


Lorraine, join a club or get instruction book. An optical telescope which uses lenses is known as a refracting telescope or a refractor; one which uses a mirror is known as a reflecting telescope or a reflector. Besides optical telescopes, astronomers also use telescopes that focus radio waves, X-rays, and other forms of electromagnetic radiation.

Hi just purchased a used Sciencetech 262... Can anyone help me figure out how to put it together and use thank you

Sorry that is an off brand imported telescope. Never heard of that brand.

However, there are basically 3 styles of telescopes, a REFRACTOR, a REFLECTOR(that has mirrors), and an SCT with both a front corrector plate and a mirror.

You probably have either a refractor or a reflector. Meade maintains a web site with all of their manuals- lokk under the 4.5 inch Reflector heading, or the Refractor heading for one that is similar to your scope. They all assemble and are used in the same way.

Do not know how to get black cover off of lense


First are you sure you have the CORRECT end of the scope pointed toward the sky? On a reflector type telescope that uses mirrors, the focuser is on the side of the tube on the UP end of the telescope. The mirror is in the bottom.

Mose caps simply pop off, others unscrew. You may be trying to remove the BOTTOM mirror!

We've a 600X power edu-science telescope which seems to be missing the inner ring which might be what the instructions call a secondary precision mirror.


The secondary mirror is a small tilted mirror near the front end of the telescope mounted on what's called a "spider". It reflects the light from the large mirror in the bottom back out through the hole in the focuser.

Usually these are already assembled and in place when you buy a reflector style telescope.

Problem with reflector telescope ta1100-102


It is NOT in focus. Practice focusing on a distant object during the day time.

I bought a102 astro-nova telescope why is there a mirrow in the middel of the veiwing zone it does not make sense we can not see anything.


This is a REFLECTOR style telescope. Ligght enters the main tube hits the large mirror on the bottome and is reflected back to the small mirror which is tilted and reflects out into the focuser and the eyepiece.

The focuser is on the FRONT of the telescope. This is the end pointed UP==

Go outside during the day and practice focusing on a distant object using the eyepiece with the largest number written on it. You will NOT see the second smaller mirror when you are in focus.

Can't see out of eye piece


This is a reflector style telescope. The MIRROR is in the base! Light enters the front near the focuser and goes down the tube and bounces off the mirror and back to the front and through the eyepiece. The EYEPIECE end is pointed up.

Your scope TUBE should look like the reflector telescope on this web page:

http://www.amazon.com/Edu-Science-Astro-Nova-102-Telescope/dp/B001NLOQN2

Wish you had NOT bought this telescope. For about the same price you could have bought this:
http://www.telescope.com/control/product/~category_id=classicdobs/~pcategory=dobsonians/~product_id=08942

The scope above has a 6 inch mirror which is almost twice the size of the scope you bought.

HI All I noticed theres only one way to mount a orion spaceprobe 3 eq telescope onto the tripod. This equatorial reflector seems like its mounted upside down when tring to view things. Tech support is gone...


Not upside down---

The eyepiece and focuser is on the FRONT of the telescope. Light enters the tube-- hits the mirror on the bottom-- and bounces back up to the small secondary mirror which reflects it out to the eyepiece.

It's called a Newtonian design--
