Can't get images

I just got this telescope at 2nd hand store. not familier with them. can find images without lenses, but once i put lense on, very blurry. tried focusing VERY slowly but no luck. What to try next?

TOO much magnification! Hate to tell you but the MAXIMUM magnification for any telescope (all things being perfect-- like optics, and sky conditions) is 50 times aperture. So max for you is about 125 power.Normally only about 30-40 times aperture is possible. So about 90 power is your normal max magnification.We see this every Christmas. People buy scopes that say 275 power or 500 power on the outside of the box. It's a LIE!Even in my 8 inch LX90 I rarely go above 200 power, and only when the sky is clear and very stable. Use the eyepiece with the largest number written on it which will be your lowest magnification.

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--

Cant get an image.Is it right that the view finderimage is upside down


The image of all astronomical telescopes are upside down (SCTs are upside down and reversed). RACI (right angled, correct image) finders do produce a right-side up image. For daytime use a erect image prism eyepiece.Follow below instructions (except 7 in your case) Get Stellarium or another fine astronomy programDuring the day, point the telescope at a part of the landscape about 100 yards away.Use the lowest power eyepiece (highest number) in the focal tube. Center the landscape object in the telescope. Align the finder scope so that it points exactly where the main telescope is.At night, leave the scope out to reach thermal equilibrium (about an hour for small reflectors and refractors)If the scope is on a EQ mount, polar align.Point the finder at the moon. The moon should be in the main scope also.Practice finding the moon before you start on the planetsOnce you are comfortable with the moon and planets, you can go for the deep sky objects

Can't get images


These are good scopes for the bucks.What size eyepiece in mm do you have. What are you aiming the scope at? Try your largest eyepiece in mm at the moon.

I culmated my telescope and cant' get it to focus in. Using the focuser the image stays one big blob without any distinguishing figures.


Did you put an EYEPIECE into the focuser? Probably NOT.Take the scope out in the day time, put the eyepiece with the largest number written on it into the focuser. Practice focusing on a distant object. TURN the focuser knob slowly until the object comes into sharp focus.

I was given the power seeker 76 already assembled,,all images are up side down. i have taken the terlescope apart 20 times and cant get image thru scope right side up


Powerseeker 76 is reflector telescope that is why he gives up side down images. If you want right side up please you buy imege eractor eyepiese. Thanks. - Dhananjay Raval - INDIA.

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 cant get an image or focus - Bushnell NorthStar 78-8830 (525 x 76mm) Telescope


Put the eyepiece with the largest number written on it into the focuser. DO NOT USE the 2 x barlow if you have one. Go outside during the day time and practice focusing on a distant object, by turning the knob on the focuser in both directions until you see a sharp image.

How do I focus on the moon. Model 1400150. I have been gifted this telescope. Tried to focus on moon. Dont know how. Took big cap off end. Looked throughscope on top of large cylinder. Tried to focus eyepiece lens but cant even see image. So I must be doing something really wrong. Sorry. Very novice. 1st time. Had kids with me but we all were disappointed. Hope you can help get me started. Regards Gary


First, use the lowest power eyepiece, that's the one with the high number on it with 'mm' after the number.for a refractor telescope (uses lenses), you might have to add a diagnal lens (either 45 degree or 90 degree, whichever one you have) to focus on an object. attach it in this order:low power eyepiece-->diagnal lens-->main telescopefor a reflector telescope (uses mirrors, a telescope with a big tube with a mirror at the bottom and a focusing knob on one side of the tube). the open part of the tube points to your target.hope this helps :D

I bought a skyquest xt10i telescope and am trying


A star is always just a point of light no matter what magnification you use! If you are seeing a "disk" when you focus on a star you are NOT focused! Make it a tiny dot.Why not try focusing on the moon or Mars and Saturn. You will always need to re=focus slightly when you move to another sky object.
