Good 4 Telescope How Good Will This Telescope Be?

Mags hello --
I am afraid that this is not a very good telescope for astronomy. You can to see the moon and Jupiter. Stars will be the same without (it's yes, the same at every amateur level, they look look). You'll also be able to see a group of faint stars, but little else. It would probably be better with a decent pair of binoculars. In fact, almost all amateur astronomers with a telescope - even if they reach very high price.
The opening of this field is the same as the diameter of the front lens, if it is 70 mm, slightly less than 3 cm. It is small enough to be able to see much. The glasses are pretty standard, and probably at the lower end in terms of quality. They describe the mount / tripod (this is important), so I guess it is very unstable. The Barlow is not really useful, and the prism assembly comes only in the way of astronomical purposes.
All in all I would do much better if stored in the place now and for a better instrument ifYou have this option. Meanwhile, one night take out the binoculars to a series of maps and learn the night sky. Good Luck and Clear Skies!
She added: "I suspect that my eyes an extra means having a focal length of 4 mm. The answer is no. This would give more to gain, but increase) is not very important in astronomy (contrary to popular belief. Back For example, the Andromeda galaxy fills a region of the sky, is 4 times as large as the full moon. It is easily visible with binoculars decent evening in the northern hemisphere. The reason you can not see with the naked eye, is not too small. For it is too low. The larger the diameter of the telescope is more light in the eye and provide a consistent, you can focus in the dark objects. Rare high magnification. Not worth the trouble for a purpose other than the moon .
What is needed in the area of a beginner, it is not the extension, but:
1. Aperture (diameter) - this area is very small opening.
2 Solid Assembly - I doubt that this support is massive.
3. Easy installation and portability - this area is probably easier to configure and easier to move and you want it.
4. The overall quality - I suspect that it is not high.
5. Suppliers reliable and well informed - I do not know the source that you buy. When a department store or eBay, you made a common mistake.
Add a 4 mm eyepiece on this scale would address one of these criteria. So not worth much, and it would be difficult to find things.
I'm not saying that this area is not worth the effort. If you remove have already purchased, then by all means you use it and to learn the night sky. You can look at all the planets (except maybe Neptune), the moon, some groups of bright stars, the Orion Nebula, the Lagoon Nebula and the Andromeda galaxy. That would be my first choice for an area, but it can work for you. Try to avoid simple frustration when you find it difficult to find and track targets or see detail. There is no better tooland improving the quality of time in the face by investing in a next time spent. If you have not yet purchased - no.
Not much, is very fast for a glass of what to expect a little chromatic aberration, and the spotlight suddenly "Convergence" will cause problems with your eyes cheaper to go with that.
Probably a decent margin enough to recognize the nature of (older?) Search and that's exactly have what I am saying that "the scope is actually made (as it appears on a prism in place, although his description is very clear ), but I would not expect a very good view of the sky his own.
The opening is 70 mm.
It has seen a basic telescope, well, now you have a timer, you need the items you want to see length, with a driving device, you can follow all things through the night sky Wat do in addition to the possibility of long exposure photographs.
In fact, not in a position to get good photos of the stars, because it so far.
However, you can see the planets (Jupiter, Saturn, some of the best views IMO)
And you should be able to also see some nebulous:)
What is the telescope?
Several prominent positions
Do not buy this telescope! This call is similar to what we "department store" telescope.
