What can you see with a 8 inch Dobsonian telescope?
What can you see with a 8 inch Dobsonian telescope?
The Moon, the bright planets, bright binary stars, bright open and globular clusters, bright nebulae, and bright galaxies are all possible targets.
How does a Dobsonian telescope work?
Dobsonian telescopes are a type of reflecting telescope that is very popular in the visual astronomy community. They work by reflecting the light travelling inside their optical tube assembly (OTA) from a curved primary mirror to a flat secondary mirror which then directs the light to the focuser.
Is an 8-inch Dobsonian good?
The consensus is that 8-inch is the best “size” telescope that hits that sweet spot between portability and aperture. If you are on a very tight budget, then go for a 6-inch. The best Dobsonian telescope has a large aperture, is easy to use, and reasonably portable.
How good is an 8-inch telescope?
The 8” Dob is a Dobsonian at its core, so it has the makings of an excellent deep space viewing telescope. Its large optical diameter provides great value as it’s large enough to get that wide field of view and great detail without killing it in weight, handleability, and price.
Why can’t I focus my telescope?
Many refractors rely on the star diagonal to bring the eyepiece into the focusing range of the telescope, so if you can’t get anything to focus, make sure you always have the diagonal in place between the eyepiece and the telescope. The Moon should have a crisp edge to it, and stars should focus down to a point.
How big is the base of a 200p Dobsonian?
Allowing for this it will be around 26KG in total. The 200P dobsonian is designed so you can carry the base out and then the telescope, its very easy to sit the telescope in the base once outside. The base will be around 15KG and the Telescope itself around 11KG.
What can a Dobsonian telescope be used for?
Sky-Watcher Dobsonian telescopes provide good all round performance for observing the Moon, planets, Deep Sky Objects and nebulae. The Dobsonian mount, popularised by John Dobson in the 1970s, is a simple and efficient method of mounting a Newtonian reflector.
How does a Dobsonian telescope work in azimuth?
It is a box-type mounting which allows the telescope to pivot in altitude, while the box itself is rotated on a base in azimuth. The secret of the design is to correctly balance the optical tube and use materials that enable it to moved easily when nudged but stay in position when not.
