Go here for complete plans for a Dobsonian telescope.

go for the 8-inch. it's the perfect beginner's telescope.
you'll be able to see deep sky objects (DSO) like planets, galaxies, stars, etc.
the 6-inch is okay, but the 8-inch is better --> bigger is better.
with the 10- inch, you'll see more deep sky objects, but it's heavier and harder to transport.
the 8-inch telescope is a good compromise. you'll see more objects with an 8 inch than with a 6-inch.

also go here for a free star atlas

go to the bottom of "cloudy nights" website for the Updated Version 2.0 star atlas

good luck with this project :D

How to look at stars

Your telescope is fortunately of a type (a refractor) that is ready to go once you take the lens cap off, and mount an eyepiece in it.
The magnification you will get does not matter much if you are looking at stars, but it is the focal length of the scope, 900mm, divided by the focal length of the eyepiece. So for example 900/20 = 45x.
The next step is to obtain a sky chart such as

(adjust this to show the local horizon) and then either print or take the PC outside and match it with the constellations you see.

Some stars are more interesting to look at because they are coloured (Betelgeuse - Alpha Orionis) or actually double stars (Rigel Kent - Alpha Centauri). See

Another way is to identify a Constellation, and then look up Wikipedia for that. You will find info on the resident stars there eg

Your LOCAL Astronomy Club! Join NOW!

As the Treasurer for one of the largest Astronomy clubs in the USA, I can tell you that NOTHING has helped me along with the Astronomy hobby more than the CLUB! and it's members.

Most large Astronomy clubs have:

Monthly meetings where all things about the club and the hobby are discussed.

Free star parties where members set-up their telescopes and show the sky to the general public. They share all manner of information about the hobby to the people who attend the star party.

Some club's have a "dark sky" location, usually a large field, where members can take their telescopes away from city light pollution and really SEE the sky! Our club has a bunkhouse, meeting room, and domed observatory with a 16 inch computer controlled telescope at it's dark sky site. Additionally we have several nice loaner scopes at the site that the members can use for free.

Many clubs, ours included, have close ties with a local college or university. Our club is sponsored by the Physics Department of a nationally known university. We use a campus lecture hall with full multi-media facilities to hold our monthly meetings.

The club offers member discounts on the two major Astronomy magazines - Astronomy, and Sky and Telescope.

Most club's have Special Interest Groups called SIG, that specialize in certain aspects of the hobby; like Public Observing, Astro-Photography APSIG, and Amateur Telescope Making ATMSIG. You can get specialized assistance with whatever interests you, or join others and show the sky to the general public at a local star party!

What does this all COST? Not very much really! Our club dues are $40 per year. A very small price to pay for access to the dark site observatory, and speakers at our monthly meetings; along with all the other club activities.

So my advice to you would be to JOIN a local Astronomy club and get involved with it's activities. The Astronomical League has a list of clubs BY STATE, at this web site:

Join now BEFORE you purchase your first telescope. The members will help you purchase the right one to fit your Astronomy interest.

Clear Skies!

I see images in the daytime but at night complete blackness

Your scope must be pointed directly at the objects in the sky. They are very tiny, and no bigger than the tip of your finger held at arms length. Try for the moon first, and buy a good star chart like, "Sky & Telescope Pocket Star Atlas" available on

All telescopes have very small fields of view, 1 degree or less usually.

I have just bought my son a NG70CA telescope. Have no manuals and cant find any on the web. As my son is very interested in star gazing..we can see the moon quite clearly but little else. Having seen...

Try to locate a local Astronomy club and attend their star parties. Also download the free monthly star chart at: Objects in the sky are tiny. Your scope must be pointed directly at them or you will not see them in the eyepiece. Make sure the finder scope is aligned with the main tube perfectly. Then use the finder scope to align the telescope.

You are only going to be able to see the moon and several of the brighter planets-- and maybe a few bright star clusters -- like M44.

Practice focusing during the daytime on a distant object-- and only use the eyepiece with the LARGEST number written on it-- try to locate a local Astronomy club and attend one of their free star parties.

What eyepieces sizes have you used?
Try using the largest eyepieces you have (20mm, 25mm or higher) for a wide field of view. If your eyepiece is to small (maybe 15mm or below) you will have too much magnification and the moon will be a blur.
