I am looking for Galileo cc-2 replacement parts. I have no idea what any of these parts are because I know nothing about telescopes. There is no lens in the eyepiece, so I need to replace whatever is needed.The only numbers I can find are the cc-2 model number along with 700mm focal length and 60mm objective. If any one has an idea on where to get some help on this I would be greatly appreciative. Thanks for your time, Joe

I have a broken elevation spindle, the little aluminum casting that passes through the plastic driven gear and ultimately ends in 4 tapped holes that the sleeve bolts to that holds the optical tube. We tried to repair this with JB Weld Epoxy, and it held for one night, but it broke again when moving the scope. Is a replacement spindle casting available from any source? Although I am an engineer, and if money were no object, I could probably reverse engineer this part, produce a blueprint from many careful measurements, go to a foundry, and have a new one cast (or drop forged) in stainless steel, it would cost many times more than the telescope itself, and for that price I could just get a much bigger scope with a far more rugged mount. The original damage happened when the motorized mount was in a duffel bag that someone knocked off the tailgate of a pickup. It fell about 3 feet and impacted on hard rocky terrain. Visually it appeared to be undamaged until the weight of the tube was applied, then it was obvious something had broken. I have some pictures of the part and exactly where it goes if it has a different name than what I described. So i need a good part number for this part, a valid address and price and delivery information to order one from. If someone has built an aftermarket one from something like stainless steel or similar stronger material, so much the better, as it might also stiffen the scope and reduce vibration and oscillation when one bumps the eyepiece while observing.


Meade "MAY" sell you the part? Usually they want you to send the scope back. Call customer service:http://www.meade.com/support/index.htmlThis is also a problem on the ETX model scopes. There are some ingenious fixes posted on the Mighty ETX web site.Here:http://www.weasner.com/etx/menu.html Bassically bolts, washers and nuts.Search the web site for Broken DEC knob.

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.

The piece you look through with the glass is gone on my telescope can i get on.700mm focal lenght, 60mm objective lens (f/11.7)


You mean the eyepieces correct? You can buy these on the internet-- here is one of hundreds of retailers-- you will need to know the size of the eyepiece hole--- measure it-- usually 1.25 inch but sometimes .965 inch.http://www.agenaastro.com/

The rand and pinion focusing mechanism has twisted off and one part seems to be rattling around in the tube.somewhere. Where can I get this repaired? Or can I do it myself. Thanks.


You can buy a new focuser from several on line sources. Here are two-http://www.telescope.com/control/telescope-focusershttp://agenaastro.com/parts-accessories.html?SID=d6pirrift40nfgsrmhsllep913&cat=66

Bushnell has a warranty web site where you may be able to get that part:http://www.opticsplanet.net/bushnell-warranty.htmlOR a well stocked hardware store may have something that would also repair the tripod leg.

I own a Mossberg Model A "Spotshot" 20X target spotting scope which I bought back in 1953. It is in excellent condition except for the fact that all of the internal tubes and lenses were removed for cleaning some years ago and I lost the order in which they have to be re-assembled. The optical train consists of the following: 1. optical "stop" with 1/2 " hole, thickness 1 mm 2. aluminum tube spacer, length 41 mm 3. " " " " " length 19 mm 4. " " " " " length 18 mm 5. " " " " " length 5 mm 6. Lens, dia 12 mm, focal length 22 mm 7. Lens, dia 9 mm, focal length 16 mm 8. Lens, dia 3 mm, focal length 22 mm 9. compression coil spring 10. objective and eyepiece ( No question about where they go.) I measured the focal lengths using the sun as the source, and a mm scale. They are approximate. I thought I could use the above information to figure out the order of assembly, but so far without success. I'm down to trial and error, which is driving me nuts. I sure hope you can help. Thanks in advance for your help.


As I had rebuilt many zoom lenses in my lifetime the ground glass on the back side is what you are looking through on any scope. It magnafies that way to capture the entire image of the frame your focussing onto. Now the lens the nearest to the eye is producing the smallest image and graduate in a larger size each steped up.. Look at the below link to get an idea
