There should be 2 sets of adjustments to be done. The first is to sight from the eyepiece holder, and see if the diagonal has the back mirror centered - don't be concerned about the off-center of the main mirror. Once the diagonal is centered, then use the adjuster screws to bring the main mirror into line. Adjust first one way then the next (in or out). When done, your eye should be centered in both mirrors. Then align the finder, and away you go.

Here?s my problem : My scope model is LX200R 14?. I?ve pulled the focuser shaft out of the focuser arm pin. I?ve turned the locking lock knob several turns before putting back the focuser shaft. I noticed that the primary mirror cell turned together with the lock gear when I turned the locking knob ! (Is this normal ?) Afterward I tried to hook the crosshole in the focuser screw over the focus rod again. Here comes my problem: the focus arm/rod is not aligned to the center of the focuser opening at the back plate of the scope! So I have to tilt the focuser shaft in order to hook the crosshole over the focus rod. At that skewed position, I can never reattach the focuser assembly to the back plate! I?ve tried to rotate the primary mirror cell and thus the focuser arm, but it comes to a STOP, short of the center position I desire. I?ve also tried to turn the primary mirror cell a full circle : by 360deg and see if the focuser rod would come to the center position : but no, it comes to a STOP, this time even more short of the center position. I am now scared : why the focuser arm pin has come off its original position ? Why there is a STOP preventing me to position the focuser arm pin back to its original center position ??? Can I ever hook the crosshole back over the focus rod and reattach the focuser assembly again ? Regards, Stewart


Steward, this is Joe Lalumia-- I have seen your post on various forums. The 14 inch is different from the other smaller LX200 scopes. Probably Dr. Clay, and or Andrew on the Yahoo Group LX200 forum will know the answer because they service these scopes.Post a message there (register for free) and one of them will answer you about that very nice scope.Clear Skies! Joe

Hey guys! My brothers chipped in to get me a telescope for my birthday. It's a celestron sky prodigy 70. I took it out a few times with zero experience except for what I picked up from reading the owner manual. Please excuse my language as I do not know any common terminology nor am I very good at trig but I at least know the terms relating to math( if thats what it really is talking about). So, when I look through the lens I get a nice sharp and crisp image with the factory provided lens. I know this is an entry level telescope but I want more magnification. So I bought an x-cel lx 2x Barlow lens and a 24mm-8mm zoom lens. I know the max magnification is 165x and the focal length is 700 so that puts my strongest eye piece at a little over 4mm meaning a 5mm is pretty much what I'll get out of it. I tried the Barlow and the zoom lens a smidge over 8 (9 I hope it was at) and the image is very soft. Then again I am in Los Angeles and looking out of my window through a fairly heavy marine layer. But the image comes out sharp if I use my factory lens, or just the zoom, or my already provided 24mm with the Barlow or the zoom at a lower magnification with the Barlow. My provided 9mm with the Barlow produces a blurred image and I tried to focus but it still seems blurry at best. I think I'm safe to say a 9mm on a 2x Barlow is still within the max effective range of zoom? I'm wondering if I shouldn't expect much out of the telescope or if I should return either the Barlow or the zoom lens or both and get some higher quality object specific lens instead. Or maybe I'm not focusing correctly? Or a zoom should not be used on a Barlow? Any insight would be very helpful.


Hi, I can see you'r statring a interesting journey in amateur astronomy. Which can be really amazing but also disappointing, because usually people are expecting too much (specially after viewing beautiful astronomy pictures on internet).Before we go back to your question lets go over some basics here:Your telescope has a F10 aperture (Focal lenght / Diameter).So to be able to see the maximum amount of details from it, the smallest eyepiece you need is a 10mm (eyepiece mm = to f number of thetelescope).Then it's easy to find the maximum useful magnification: 700mm (focal lenght) / 10mm (eyepiece) = 70x Ok but why does the manufacturer say that it can be at a max of 170x... they are not really lying, if you get a smaller eyepiece it will make the image bigger but will show no additional details than a 10mm one. But the image being bigger it can make details easier to see.That for the questions about magnification an image quality.The more pieces you put between you eye and the telescope mirror, the dimmer and less contrasty the image will be. Especially after you go higher that the maximum useful magnification.Hope this helps. And enjoy wathching the stars and planets, it is a always a beautiful sight.

I have a 49114500 and at the rear mirror area, there are three manual adjustment screws. When I remove the large front cover, I notice that the mirror is not centered on the front 'three sectonal' scope unit (?). Are the three adjustment screws in the rear used to center the 'three sectional' device to the mirror? How? Thank you in advance...


Those are the PRIMARY MIRROR collimation screws. Watch this video:http://www.andysshotglass.com/Collimating.html

Battery connection I was about to set up my telescope (meade etx125) and I heard something loose rattling around inside. I removed the bottom and a piece of plastic fell out, from one of the screw fittings. That's not the problem. When I tried to catch this as it fell I pulled the battery connector wires out. I know an excellent soldering guy, but I would like to know where they were connected. Just to be sure. I hate setting up this telescope as it is. So any help would be great.


Hopefully you pulled out the ones that simple plug back in! -- check out the Mighty ETX web site for disassembly instructions--http://www.weasner.com/etx/menu.html

While hiking, I lost the left eyecup on my Celestron ED 6.5 x 44 binoculars. Not lost is the eyepiece lens. The lost part is a rubber cup that may also include a metal sleeve with a fine internal thread. It seems like the sleeve would screw onto the body while having the rubber eye cup stretched over the other end. I can show with a picture. I need the part or the manual diagraming the part in order to get the binoculars working again. Thank you.


Http://www.celestron.com/c3/page.php?PageID=37try to write or call the manufacturer on this support site..I tried to find a tab with parts but there seam to not be available or the parts are described by functions ..and yours seam to be a sub-part ..Just write them or use the phone ..and if they have such a part they will guide you to order it ..

The Celestron Nexstar 4SE makes a weird cracking noise when you press the left or right arrows on the controller. I tried taking it off of the tripod, and it still will not rotate left or right, even if you do it manually. It does rotate up and down. Is there something that is blocking the telescope from rotating? Is there a mechanical problem? :|


Is the AZimuth clutch locked down? Then either a gear is broken inside or the worm gear inside has slipped and is not engaing. You can return these to Celestron for repair, here:http://www.celestron.com/c3/page.php?PageID=37
