Suggested Questions And Answer :


Lens came off-where do springs go?


There are a bunch of Sky Tour telescopes ---http://www.opticsplanet.net/bushnell-warranty.htmlwhich model you actually have??I am assuming you have what is called a Dobsonian mounted reflector like this one:http://www.bushnell.com/manuals/telescopes/78-4500_Voyager.pdfIs that correct?

NEED A FREE OWNERS MANUAL ON HOW TO USE THIS TELESCOPE THANKS p.w.


Most of these small telescopes do not have an operators manual-- however Meade maintains a web site for the telescopes with manuals. Find one similar to yours and download the manual for free.www.meade.com look in Customer Service --- Manuals

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.

Bushnell Model 78-4678


I have the Bushnell model 78-4678 and also was looking for the owner's manual, but couldn't find it. I decided to call Bushnell at this number (800) 423-3537 and talked to tech support. I explained that the telescope was hand-me-down and needed an owner's manual. They are sending me the owner's manual for free! So far, it sounds like this is going to work!

Tasco 40-114675 - new telescope. I am lost. my first telescope and the directions are useless. I don't know the first thing about them. how are the lenses supposed to go? do I use the barlow all the time with the 4mm? or just use the 4mm directly? what do I do with the 5 inch tube? do i remove the cap at the end of the main body to veiw the night sky? please help.


DO NOT USE the barlow at all your scope is too small to get that much magnification.Put the eyepiece with the largest number written on it into the focuser and point it at a distant object during the day time. Practice focusing. The moon should be your first target at night.Read my tips on my profile page.

Just black Hi I just recently bought a Meade ds-2114ats-tc and I tried to use it last night with the kids, unfortunaltey after we set up the telescope all we could see was black. Yes we did make sure that the lens cap was off and that there was nothing blocking anything, we also tried setting it up in a couple of different spots in the back yard where we were close to a light source and also away from a light source. Basically everything I tried did not work but I am new to this so I could be doing something wrong still. I tried to manually look at the brightest star in the sky and still nothing....just black. Could I be setting this up in an area where there in either not enough light getting in or to much? This is my first time using a telescope so I don't even really know if I should be setting this up in the complete dark area or with a light source around like a backyard light for example. I am extremely confused please help.


I just got one of these today and they are different. My guess is you are having a focusing problem rather than alignment. Assuming of course you are removing the larger dustcap and not just the smaller one ha ha ha. The instructions include how to align but maybe you can use this Mine has two dustcaps, one full size with a smaller one in its center. Had the smaller one been offset it could have been used as an aperture stop to reduce thermal effects on bright objects such as Jupiter and the Moon. Another thing is a built in barlow within the focuser draw tube. This inreases the focal ratio of "f" number and makes align far more trickier than if it had been a straight Newtonian. Set-up the scope under and point at the bright blue sky in the day time. Pull off the small center dust cover and make sure the diagonal holder is centered under the small hole in the larger dust cover. If not that can be accomplished by adjusting the three thumb nuts on the front edge of the tube. Once this is done remove the larger dust cover and peer into the focuser from the side with the eyepiece removed. You should see blue sky and all the components should be centered. One can judge fairly well that their eye is centered but a simple trick is to draw an eyepiece sized circle on a piece of paper and using a pick or pencil, poke a small hole dead center on the circle. Place the circle centered over the draw tube and peer through that. No other tool will improve on the accuracy of this almost free and simple one. Now moving your eye closer to the focuser you should see the reflection of your own eye or in this case the hole in the center of the paper. The paper reflects and transmits enough light that it provides a bright enough targert to canter. Now you must experiment to determine which component is mis-alighned and what adjustment is required to correct. Try flexing each componet before loosening any adjustment screws.This will give you an idea of which component and in which manner it needs to move. Now my guess is, while you have some mis-alignment the almost f:9 focal ratio makes the image extra dark and so contrasty that if you are out of focus all you will see is dark. With your 28mm eyepiece, now point the scope at a daylight scene some distance away and bring the image to a focus. Note hoe far your draw tube is extended so you will be in that neighbohood come night time. I suspect this was your problem more than mis-alignment.
