Problem with orion 6" dobsonian mount telescope

The mirror for the eye piece has fallen off.  It's i small (3") cylindrical tube with an angle cut on one end and it has a mirror affixed to the angled end. The inside of the small tube has some foam in it.  I think when you look through the eyepiece that mirror reflects the image that is on the 6" mirror at the end of the long main 6" tube of the telescope.  So without that small mirror you cannot see anything.  I found it laying on the bottom of the long 6" tube.  Don't know how it came loose.  I cannot see how to re-attach it and if I could would it need to be calibrated somehow?  I have looked locally for a repair service but haven't found anyone.

The small mirror is usually held on with double-sided foam tape. That tape us used, so the small mirror is not stressed by the metal fittings with temperature changes. Clean the residue from the holder and the mirror, and apply fresh double-sided mounting tape and carefully place the mirror so that the main mirror is viewed from the eyepiece position.

I am a beginner looking for a good telescope. I am currently looking at a Celestron Skywatcher telescope. There are three lenses which comes with it: super wide 10mm. lens as well as a wide angle 25 mm....


Magnification is the LEAST important property of a telescope. Quality optics and aperture are much more important.

The best bang for the buck is a reflector style telescope ion a Dobsionian mount. You get the most aperture for the least amount of money. Like this one--

The scope above has 6 inches of aperture and is mounted on a very stable alt az mount called a Dobsonian mount.

I am looking to buy a telescope for my husbands 50th b-day and fathers day. How do i go about choosing one?


Read these two articles-

http://texasastro.org/telescope.php

http://texasastro.org/mounts.php

A 6 inch or 8 inch Dobsonian mounted reflector is what we usually recommend for a beginner. Like this one:

I have a swift astronomical telescope model no. 859 (no D). I need an owners manual and information on how to order parts. Mark J. Lanza


This is a 6 inch Dobsonian mounted reflector. They are VERY simple to assemble-- only two parts-- the base and the tube. The small finder scope goes on top. The eyepiece goes into the focuser. That's it.

No manuals exist for that brand but all of them assemble and are used in the same fashion. Here is a manual for an Orion brand Dobsonian just like your scope.

I have an Orion SkyQuest XT8 Dobsonian. I have had it for 6 years or so. I can't see anything through the eye pieces. It just has black spots. is it the eye pieces or the telescope?


Put the eyepiece with the largest number written on it into the focuser. Go outside during the day time and practice focusing on a distant object.

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.

How would you rate +Venture RX-9 telescope?


If you read down this page there is a manual
http://cs.astronomy.com/asycs/forums/t/30807.aspx

This is a cheaply made in China reflector telescope. It is mounted on a small equatorial mount which is too small to support the tube. It will be very shaky. These scopes appear on Craigslist after the owner determines they are really just a "toy" telescope.

You can do much better for their $249 asking price. Look at a Dobsonian telescope like one of these.

Gluing the mirror back on the mount


A better solution would be to buy a commercially available mirror holder and mount this in the bottom. On these the mirror is held on the edge by clips --

Confused with RA setting circle with Orion XT8 Dobsonian


An Orion XT 8 DOB cannot be polar aligned??? The mount is ALT AZ ---

You would need an equatorial platform to polar align. There are no setting circles on a stock XT??

Mirror fell out and broke I've got the 25 mm eye piece and lost the others


Not worth fixing-- next time you buy a telescope look at a small Dobsonian like this one--

http://www.telescope.com/control/product/~category_id=dobsonians/~pcategory=telescopes/~product_id=09804

or the 6 inch version of the same scope--

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--
