search online for the manual...that shows a complete assembly...put in the full model name "Celestron 31042 AstroMaster 114 EQ Reflector Telescope" followed by the word manual in your search engine, that should help

I cannot seem to get it attached...do you remove the existing rubber "gasket" around the eyepiece and place this one on instead? Should be simple, but not finding it so.

Hi Kenneth, I am so sorry, but I don't know. Perhaps it might be good to enter your camera model in a search bar followed by eyepiece extender. I apologize if my response is very basic, but I'm hoping it might help.

I have the exactly same problem. Don't know where to buy the correct eyepiece.

It comes with two eyepiece sets. I don't see a mm setting. One eyepiece says WF 20x . The other eyepiece says WF 10x/18. I did a little research online, and apparently /18 means 18mm. I'm not sure what the 20x eyepiece is. Until my son because interested a couple years ago, I hadn't used a scope since my college biology GM course; and now I'm learning along with him. I suspect life science majors, grad students, and professionals will need to buy better eyepieces. But these have been great to show my son prepared slides and teach him to be aware of a microscopic view of our cosmos. Hopefully our interests will lead us someday to considering better eyepieces in a year or two. But, if you're looking for more now, you may need to budget that into their purchase better eyepieces. Or you can contact the business and see if they would replace these eyepieces, add better ones, and for what price. This has been my only business with them, but they were remarkably attentive and responsive to this novice user.

Yeah the exact same thing happen to me. I hope the lens it's stuck to is not too expensive. Cause the way I chose to remove it was by forcefully twisting it off. If it's a cheap kit lens a little plastic piece will break off. But the lens will work just fine. It won't destroy it, just modify it a little.

there should be an owners manual. check the Orion website. Otherwise return it to Amazon and have them ship a replacement. I returned my first one and the replacement was perfect.

Twist up, pull out, pop another one in. If it is too small to grip an eyeglass screwdriver or pin can be used to leverage it out.

Get the celestron powertank (dont forget to charge it once a month), i also bought the celestron eyepiece set, great set and a good case with it. Also use the two star align, three atar doesnt work, and google for how to set it up as you must put the alignment stars in the middle of the eyepiece then move it left down up right (as the star looks in the eye piece), then click to set it as an alignment star. It will then track all night usually after one quick up movement once aligned. It is a brilliant scope, good luck!

I have never had an eyepiece come off inadvertently, but I can say the DK-21M seemed very tightly adherring when I installed it. I have since given the camera to my son and have not heard of any problems from him eitherr.

Thanks EvanThat does make sense.I have also since found out this item is discontinued by Celestron and replaced by the avx mount. May hunt to buy one of those instead but imagine same applies.

It has been awhile since I took it out of the box. Do not remember the eyepiece and eyecup, but everything else you listed came with it. Hope that helps.

If you want, I found this online, see if it helps?: http://www.telescope.com/Orion-StarShoot-USB-Eyepiece-Camera-II/p/102298.uts

In my opinion, this scope was very poor. I had problems with assembly, and the scope did not work as described. My recommendation is you return it and put that money towards a better starwatcher. We were looking so forward to seeing the night sky, and were unable to have the telescope work. I hope this was helpful. In my opinion, the pieces not working as expected, is not worth replacing parts. I hope you can find one that will work for you. I, and other Amazon customers had dissatisfactory experiences when using this particular model. Happy new year!

You need to get an eyepiece and see if it works - if you are able to view things after yiu've gotten one, that's probably all you needed

Hi Naomi, The first thing you need is to have the tripod perfectly set, (check the bubble is perfectly centered) Second: use the biggest eyepiece (25mm Eyepiece). the one with the biggest number on it. This eyepiece is called the finder, because it's easier to find objects with it. Then fix your target, pick the brightest object in the sky (the moon usually) Now this is the hard to explain part... this is how I explained to my mom. Start looking at the eyepiece from around two inches, draw circles with your head looking for a light into the eyepiece, once you find a light go closer and closer till you are really near to the eyepiece (if you lose the light start all over again) The final step is to focus the telescope. You have the light perfectly fixed but not focused. Once focused, fix the object perfectly centered in the eyepiece and now center the same object in the Star Pointer Finderscope. Sorry for my English :) G

I am a new be, but when I received my scope the problem I had was getting the finder scope to match the telescope. My view was also blank. Using the wrong eye peice can cause the same problem. The wrong focal length, due to eye peice, and or the wrong eye peice tube. I had to fiddle with it for a while, I started with small tube, and large eye peice, focused the scope with the spotter scope, best view of the moon with out being there. Patience, dont throw it out. I hope I could be of help, trial and error
