Celestron colmination hi. i just purchased a celestron 76mm skywatcher and in the manual it says colmination may be required. when i look through the lens holder the image is not exactly the same as the picture in the manual. their is more black at the top of the circle than at the bottom. i tried turning the screws and i didnt notice any change. how far in can i tun th screws in without breaking something? cheers Steve

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.

Am I supposed to see the cross in the centre of image on celestron 76eq

You will see diffrection spikes when focused on a very bright object this can also appear around a bright planet. However it is very irritating, and to minimise it, make sure your scope is well collimated (optically aligned).There is too much to collimation to include here, but there are many guides on the Net

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. long eye relief lens,and a barlow lens. My question to you is, is this a good telescope for viewing objects in the sky, such as mars, moon, jupiter etc. Or do I need another lens stronger then that. I would like you to also give me an answer as soon as possible please! THANKS FOR YOUR HELP

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

I have a Celestron Newtonian telescope, 76mm, 700mm. I am trying to locate the finder scope bracket to replace a broken one. I cannot find any other numbers, but it is about ten years old.

Simply buy another finderscope. Many internet retailers sell finder scopes. Here is Orion Telescope:

Focusing Issue Last night, I used my Celestron 11" NexStar11GPS for observing and astrophotography, and it worked like a charm. Tonight, with the same equipment, I am unable to focus the telescope at all. I turned both the coarse and fine focus knobs counterclockwise as far as they will go, but every object is still out of focus--and once I reach a certain point in turning the focus knobs, the object simply moves in the eyepiece rather than becoming more focused. This problem is present with or without the use of a diagonal. The only thing I did with the telescope between last night and tonight was to mount a Celestron StarPointer (a holographic sight-type finderscope) onto the side of the telescope tube's back end with some 8x32 3/8" screws using pre-drilled screw holes. What happened?

The screws should be short enough not to stop the primary's travel, but pull them out and try it again. Good luck! George.

Does it have a name on the scope? If it has a MIRROR in the bottom it is a REFLECTOR.If it has a lens on the front it is a REFRACTOR. Look on Meade's manual web site under the header REFRACTOR or REFLECTOR for one similar to your telescope.

DON'T know how to set up the eyepiece - Tasco 49076700 Spacestation(r) 76mm Reflector Eq Telescope (525 x 76mm)

The focuser is on the UP end of the telescope as the picture shows above. Put the eyepiece with the largest number written on it into the focuser. Take the scope outside during the day time and practice focusing on a distant object. DO NOT USE the 2x barlow if you have one. The moon should be your first target at night.Read my tips on my profile page.
