Are cheap telescopes worth it?
But just as an expensive telescope isn't always a good telescope, it's also the case that a cheaper, more affordable telescope doesn't mean you won't be able to get stunning views of the Moon, planets, stars and deep-sky objects like nebulae and galaxies..

The kind of telescope that an amateur can buy, is generally not much good for looking at stars.
Great for looking at the Moon, sure And you can really tell the difference between a really cheap telescope that you might buy a 10-year-old for Christmas, and a decent 20cm reflector..
Are there any online telescopes?
A telescope's most important attribute is its size, meaning the diameter of its main mirror or lens.
The bigger the telescope, the more light it collects, which allows you to see fainter objects.
You can observe quite a lot with a telescope just 4 to 6 inches diameter..

3) Stay away from any telescope advertised for its magnifying power.- Fifty years ago, on December 7, 1968, that idea culminated in NASA's launch of the first successful space-based observatory: the Orbiting Astronomical Observatory, or OAO-2.
- Steve says: "In general, more modern mirrors will very rarely require re-coating but so much depends on how they have been looked after, and there is certainly no standard length of time you should adhere to.
It is not at all uncommon for coatings to last 30 years or more. - What makes large telescopes so expensive? It costs a ton of money to cast glass slabs meters across and then shape them to an accuracy of a fraction of a wavelength of light, then support them in a way that they won't flex or shift, and move them so they can be pointed with an accuracy of a fraction of a second of arc.
