How do i set up eye pieces and focus lenses?? Instruction manual came in chinese with no translation and we are begiiners!


During the day:
1. Point to a far (1000 meters or more) object
2. Insert the lowest power (highest number) eyepiece e.g. 25mm
3. focus on the object.
4. Align finder to match what you see in the scope.
At night.
1. Put scope out and let it reach the temperature of the outside.
2. Point finder to the moon (1st object you should always use to check scope and finder alignment)
3. Use the same low power eyepiece.
4. If everything seems fine, switch to a higher power eyepiece and enjoy the view. You may have to slightly adjust the finder to align with the main scope.
If the views are blurry, the telescope may be out of collimation. Look on the internet for generic collimation instructions.
If this still did not help. Throw the scope out! Its probably a piece of junk and will only discourage you.

Tip

Please add "If you have a .965 eyepiece holder,purchase a .965 to 1.25 adapter"...


Even though we warned you NOT to buy a "department store" toy telescope, you went and bought one anyway!

Here are a few things you can do to upgrade the telescope. Unfortunately some of the upgrades may cost almost as much as you paid for the scope! That's why you should not buy one in the first place! Anyway here are some ways to improve your "toy" telescope:

Stabilize that SHAKY Tripod!

Tie a heavy weight underneath the tripod, hanging from the central bolt. A bucket of sand will help stabilize the shaky tripod. You can also open up the legs and fill them with concrete, or sand -- anything that will tamp-out vibrations which will help your view tiny objects through the eyepiece.

Tighten up all the bolts on the tripod and mount. DO NOT extend the legs on the tripod to their fullest extent. Try to use the scope with the legs 1/2 way extended if at all possible. A shorter tripod will be more stable.


Buy a better finder scope!

The one that came with your scope is probably almost unusable. Buy a 50mm Right Angle finder scope, or mount a red dot finder. See the two links below:
http://www.telescope.com/control/accessories/telescope-finder-scopes/orion-ez-finder-deluxe-telescope-reflex-sight

http://www.telescope.com/control/accessories/telescope-finder-scopes/9x50-orion-right-angle-correct-image-finder-scopes


Replace those cheap eyepieces with better quality.

Even the low cost Plossl design eyepieces will be better than what came with the scope. Here are two retailers that sell eyepieces. Measure the hole so you know what size to buy. They come in .965, 1.25 and 2 inch sizes. The 1.25 inch is the most popular. However some "department store" toy telescopes have .965 inch eyepieces. These .965 eyepieces are largely obsolete, hard to find, and hard to see through.

Get a better diagonal.

If your scope is a refractor it probably came with a very cheap low cost diagonal. A better one will improve light throughput, and probably yield sharper images. Here are some diagonals for sale:

http://www.agenaastro.com/Telescope-Diagonal-1-25-inch-s/100.htm

http://www.telescope.com/control/telescope-diagonals


Clean those dirty eyepieces!

Keep your hands away from the glass! In case you did not, then you will need these Never take the glass elements OUT of the eyepiece! Only the outside surfaces need to be cleaned.

http://www.telescope.com/control/accessories/telescope-tune-up/orion-lenspen-mini-pro-cleaning-tool

http://www.telescope.com/control/accessories/telescope-tune-up/orion-deluxe-6-piece-optics-cleaning-kit

It goes without saying that you should check all the bolts and nuts on the telescope and the tripod and make sure they are tight.

Use LOWER magnification-

Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow if you have one.
Your small aperture telescope was NOT meant to have 525 power magnification! With a 70mm telescope your maximum usable magnification will be about 140 power.

Buy a better METAL focuser and replace the plastic focuser that came on your telescope.
http://www.telescope.com/control/accessories/telescope-focusers/1*25-inch-orion-basic-rack-and-pinion-focuser

The problem with several of these "fixes" is that they will cost a significant portion of what you spent on your shaky low cost department store telescope. You would have been better off buying a better scope and junking the toy scope on Craigslist.com. Stop buying these toy $89 telescopes, join an astronomy club and get good advice on what to buy!

Remember, all things being equal -- the bigger the hole in the telescope - we call that aperture-- the more you can see. Most objects in the sky are VERY tiny and dim, except for the moon, several of the brighter planets, and a handful of other deep sky objects. Your scope must be pointed directly at the object in order to see it. Telescopes have very small fields of view.


Clear Skies!

Viv-tel-76700


viv tel 76700 takes both size eyepieces. There is a small sleeve in the eyepiece holder that reduces the size to .965in(cheap 2 element plastic pieces), take it out and use 1.25in( 4+ element glass) pieces and you will see better. This scope has many names on it, search 76700 telescope and you'll see.

I recently purchased a Tasco Starguide telescope. Aparently the eye piece it came with does not even belong to the telescope. Will the eye piece to this particular telescope even be available for...


Telescope eyepieces are interchangeable. Most scopes come with two or three, of different focal lengths (to give different magnifications), and enthusiasts frequently buy others, either to get a wider range of focal lengths or to get better quality.

I do not know what you mean by "does not even belong to the telescope". Most eyepieces are a standard size, with a barrel of 1.25 inches outside diameter. If your eyepiece mount is that size, you can use any make of eyepiece that fits. The Tasco brand name is not associated with high quality eyepieces, so if the one you have is another make then that is not a problem in itself.

You can find many eyepieces for sale on Amazon or eBay by searching for "eyepiece 1.25". You may want to familiarise yourself with eyepiece issues by visiting THIS SITE, which has useful basic information.

The plastic part that the eye pieces fit into is broken is there a way to get a replacement part for it?


First it's only a plastic part because of the telescope you bought. Usually a diagonal is all metal.

Many companies sell diagonals they come ion 3 sizes .965, 1.25, and 2 inch sizes. Measure the hole in the back of the telescope and buy the correct size.

How much does a tasco 302675 telescope cost/


It does not matter what it costs! Do not buy a Tasco telescope. Very poorly made, some even have plastic eyepieces and plastic lenses!

Check out this web site and others for a better, higher quality telescope.

http://www.telescope.com/control/main/

I would also suggest that you look at a Dobsonian mounted reflector like this one:

How to assemble carson telescope


Look at the picture on this web site:
http://www.opticsplanet.net/carson-50mm-aim-telescope.html

Notice that the "diagonal" goes into the telescope first and then the eyepiece goes into the diagonal.

This is a very poor quality telescope with plastic focuser and even the eyepieces are plastic. Read my TIPS on my profile page. 50mm is exactly the same aperture as a pair of 10x50mm binoculars. For Astronomy the binoculars would have been more useful than this small telescope.
