NorthStar® Telescopes offer amateur astronomers state-of-the-art computer-driven location and tracking capability with simple, push-button control. With a built-in data base of 20,000 celestial objects, you simply call up your target on the hand-held control module, enter a simple "Go To" command and the NorthStar computer does the rest. Once locked on, tracking the object for prolonged viewing is automatic.
the idea is not to touch the scope but use the hand controller. so the answer is no. not recommended.

I have a Bushnell Voyager telescope and can't see anything thru it at night!


Did you set it up according to the provided instructions?
Do you have a low power eyepiece inserted at the viewing end?
Have you aimed the telescope at the moon as a basic test of
visibility?
If your telescope is not properly aimed at the target (a star or a planet, or other object in the night sky) then you will see nothing.
If the power of your eyepiece is too large and your telescope aim is
not "dead on", then you will see nothing.
Have you tried using the scope in the daytime? Do you see anything?
Aim at a specific object, or section of an object, like the top of a lamp-post about a block or two away, and see if you can focus on
it the eyepiece.
You really need someone at your side who has experience in using
astronomical telescopes. That would be the quickest way to solve
any problems you have.
Unless your question is very specific, and unless you provide as
much detail as possible about your problem, it will be difficult for
anyone to provide you with speecific answers that will help you
solve your problem.
joy,

How to import your AIM buddys into Gmail


To set it up, just head to the <a href="http://www.aim.com/import-to-gmail/">Import to Gmail</a> page and log in to AIM. Once you've logged in, it will prompt you to enter your Gmail credentials as well. When it's done, it will tell you your contacts are imported-that's it! If you head to Gmail, you should see all your AIM contacts pop up in the Chat sidebar. Note that it only imports the 38 contacts you chat with the most, so if you have more than that, it looks like you'll have to add them manually. The Upsides: You Only Need One Login; You Get AIM on Android The Main idea behind the switch is that you won't have to deal with two separate logins within Gmail from now on. The other really cool part about this is that you can log into both protocols from one IM client. Since nearly every IM client under the sun has both GTalk and AIM, this isn't a big deal for desktop users, but it does mean that Android users can now IM their AIM buddies right from Google's official GTalk app, which is great, since it's probably the best IM client on Android.<br /> The Downsides: It's Confusing and Kind of Buggy Unfortunately, the whole implementation still seems confusing at best, and buggy at worst. Your AIM buddies will no longer see your AIM screen name when you log in; instead it will create a new contact for them using your Gmail address. However, I had the problem where some of my contacts weren't even showing up in the sidebar-some were only showing their Google Talk contacts, some were showing only AIM, and some were showing up twice, like they used to (though some showed up after a small wait, so perhaps it just takes awhile for everything to register). It's not combining them, either (which would be awesome)-it's just excluding some contacts from my buddy list entirely. In addition, the 48 contact limit for the importer is kind of a drag if you have a lot of AIM buddies.<br /> If you use a desktop IM client, of course, you'll be unaffected by all this, and can continue using GTalk and AIM separately. In fact, we'd recommend doing so. Unless you're really itching to get AIM in the Gmail web interface or on Android's Talk app, using a desktop client is still the easiest way to get access to both, and we'd recommend against importing your AIM contacts into Gmail-at least for now. Have you tried the new AIM integration in Gmail? How does it work for you? Share your thoughts with us in the comments.<br />

How to use the telescope and set it to see images


It depends on what kind of telescope you have.

The method of use is somewhat different.

Also we have to know what kind of mount you have,

equatorial or alta-zimuth.

Does your telescope have a go-to computerized mount.

The simple answer for a manually controlled telescopoe is:

1. Put in an eyepiece that has the highest number printed on its side - usually 25 mm, or 26 mm -

2. Aim the telescope at what you want to see in the night sky.

You can aim by sighting with your eye along the length of the telescope or by using the finder scope (a tiny telescope usually attached to the body of the main telescope).

3. After finding a target to look at, turn the focussing knobs slowly in one direction - if the image is getting blurrier then turn the knob in the opposite direction. Do this slowly and gently, until the image looks sharp.

4. Start by looking at a large target such as the moon. It is very easy to find and to aim at.

5. Get some books on beginning amateur astronomy. You can find a wide selection of these at your local library, or Google the internet for information of amateur astronomy.

I hope the above outline helps you to get started.

I have the 30 lens for my telescope, and I can't seem to get it to focus on anything.I see light when i aim it at the daytime sky, but that is it.


If the eyepiece will not come to focus even by moving the focuser completely inward and completely outward. Try aiming it at a distant land object during the day time.

Cannot see anything


No the red pointer is not necessary- BUT you will have a harder time aiming the telescope.

Objects in the sky are very tiny. The field of view is about the size of the tip of your finger held at arm's length. VERY small! This is the biggest problem for beginners, the telescope must be pointed DIRECTLY at the object in order to see it. Try for the moon first at night, since it is a BIG target.

Put the eyepiece with the largest number written on it into the telescope focuser. DO NOT use the 2x barlow if you have one. Practice focusing during the day time on a distant object. The image will be upside down, but this is normal.

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.

This is a pretty generic Chinese made 6" Newtonian reflector. The one's I have sampled produce excellent images. Celestron has a great online archieve of its manuals. This scope is similar to their C150-HD Newtonian Model #31056. The manual can be found here:
http://downloads.celestron.com/Manuals/telescopes/c150hd_g8n/c150hd_g8n_manual/c150hd_g8n_manual_0802.pdf

Google "beginning astronomy" and you'll get a quartr of million hits. Good over view here.

While you are there get a subscription to Sky and Telescope or their other publication aimed at beginners, Night Sky.

Find a local astronomy club and join it.
