Guide :Optics : DS-2114 ATS (325 x 114mm) Telescope

I own a DS-2114 telescope. Recently the focuser wouldn't turn, and Meade sent me another one. After I replaced it when I went to use it objects could not be focused too well. What can be done to correct this issue? Thanks for your time. Pete

Hey Pete. I had the same problem. You need to zero the whole thing and re allin it before the new focuser interlinks with the brains of the teliscope.

I have the Nexstar 8. It will not auto align or manual....


You must set TIME, DATE, and SITE-- probably does not know your actual location. Read the manual and perform all of the setup procedures. Some of these have a "starting position" again read the manual and make sure you are in the "home" position before you start the alignment. Read my TIP on my profile page about GOTO telescopes, and join the NEXSTAR forum on www.cloudynights.com

Meade LX200GPS The scope does not complete the 'Auto Alignment'


Once the scope has taken a GPS fix and knows TIME, and SITE, and you do a two star alignment your alignment stars overide any automatic alignment issues. You could turn off the GPS put in Time, Date, and Site, do a two star alignment and everything would be fine. Centering the alignment stars is the "trick". Apparently the scope also finds NORTH OK, or the alignment stars would be way off. Since you pre-level the tripod already the software can FAIL on "tilt" and you still get good gotos.I would not worry about it, especially since your gotos seem perfectly fine.

Can't focus my telescope


If there is nothing on the objective lenses or eyepiece lenses then it most likely needs collimation. This is where you adjust the secondary mirror while viewing an out of focus star. You need stable sky conditions to do this.There are most likely three small screws at the front of the telescope and these are what you use to adjust it. As one screw is loosened then another is tightened. Do this in very small increments. If you have your manual it should outline how to perform this. If not go to this web site: http://www.astrosurf.com/legault/collim.html. It will show examples of how objects look both in and out of collimation. There is a section further down the page for SCTs.A very handy tool for this is to replace your screws with Bob's Knobs (http://www.bobsknobs.com/) . These replace the screws and allow you to adjust it by hand instead of a screwdriver.The other focusing problem I've experience with my Celestron SCT is to have the focus knob loosen up and then slip as I turned it so that I could never focus with it.Good luck and clear skies!-jodair

I PURCHASED A USED BAUSCH AND LOMB PROFESSIONAL TELESCOPE MODEL 78-0040 AT A HOUSE SALE - AFTER TRYING TO SET UP - I FOUND THAT I COULD NOT FOCUS THE TELESCOPE - THE FOCUSING DRAW TUBE WITH GEAR RACK(ITEM #17 ON MANUAL LIST)IS MISSING - SOMEONE PUTT AND IMAGING CORRECTING UNIT IN IT'S PLACE - HOW OR WHERE OR WHO CAN I CONTACT TO FIND A REPLACEMENT FOCUSING DRAW TUBE ASSEMBLY WITH GEAR RACK


You can buy focusers from many retailers on-line. Here is one.http://www.telescope.com/control/accessories/telescope-focusers

I have a makusutove 150 1800 telescope and I cant seem to get it to focus correctly - it seems as though the mirrors are focussing the light behind the viewing lens. I can get a focussed image if I hold the viewing lens about 4 inches behind the telescope. how can I adjust this telescope to enable a focused image with the viewing lens in the holder?


You do not have enough BACK-FOCUS, you need an extension tube for the focuser like this one:http://www.skiesunlimited.net/index.php?CategoryID=132Buy the correct size for the focuser hole--

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.

Hello, I have a celestron c9,25. I adjust a nikon D3100 with T-Ring and Adapter to my telescope. Firstly I focus to moon, using an eyepiece, then I removed the eyepiece and adjusted the Nikon. The problem is, I can't focus through my telescope. What I've done wrong?


Because the camera has a different focus point from the eyepiece. TURN the focus knob until the camera comes into focus. OR you can buy a "focus ring" for the eyepiece which attaches to the barrel of the eyepiece and is adjustable-- then focus with the camera FIRST and then insert the eyepiece with the ring on it and lift it UP until the image comes to focus-- then tighten the ring. NOW you can use that eyepiece to roughly focus the camera.

I have a viper 3-12 x44 viperascope and the focus wheel came out, the whole asembly came out . The wire of the illumination broke off. The wires was correcter and the turret at the focus wheel is fine. The pc board and washer for the illumination is still loose. I need a catologue or manual with sketch how to correct it. If this is not possiable where can ihave it repaired, i am in South Africa. The serial no. is fbe05158908, i would also like to know when ws the scope supplier toMTC OTICS - SOUTH AFRICA.

I was given a Tasco Luminova a couple of months ago that had no eye piece in it, i have since purchased one for it thinking that this was the only thing that i needed for it to work correctly. Unfortu


Tasco telescopes are not worth owning. They will only frustrate you and you will dislike astronomy. Buy a Meade, Celestron or Orion Even the Celestron 70 travel scope, although it has a poor tripod, will give you a great view of the moon and ok view of Jupiter and Saturn They are under $80
