The Dobsonian telescopes are named after John Dobson, an amateur astronomer who designed a very simple but effective telescope, where the key factor is a large aperture for little money.

Dobsonian telescopes are among the most practical instruments in astronomy. They are of simple construction and yet a brilliant idea. They essentially consist of two parts: firstly the optics, which in most cases is a solid tube or truss tube design; and secondly the mount, a wooden box also called a 'rocker box' which sits on the ground and into which the telescope is inserted. This design allows you to begin observing sessions immediately without first having to spend time setting up and aligning a complicated mount. The basic idea of the Dobsonian design came from the wish to have a big telescope at a low price, a wish that has succeeded brilliantly. A true fan base has developed since the invention of the Dobsonian telescope which is dedicated to these instruments and their fascinating simplicity and to the idea of 'high performance at low price'. A simple, elegant form of an alt-azimuth mount made to carry a Newtonian reflector was popularized by John Dobson in the late 's.

Dobsonian telescopes offer an incredible aperture-to-price ratio. The Dobsonian mount, popularized by John Dobson in the Fast and easy to set up, the Dobsonian mount consists of 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 frictional materials which allow it to be moved easily when nudged but to stay in position when not. The mount is designed to be driven by hand as opposed to slow motion controls. We were very pleased with the appearance of al the test objects — we even managed to find the Crab Nebula, M81 and M82 in near-full Moonlight, whereas the other scopes were struggling. The Pleiades M45 was just a bit too large to fit in the field of view, but the main central stars looked stunning…. Turning to Saturn, the view really took our breath away: we saw five moons, a clear-cut Cassini Division and a colour difference between the A and B rings. Not only that, but Saturn also displayed a prominent belt — with this scope planetary detail is certainly not compromised…. Fans of deep-sky observing would certainly find the Skyliner satisfying…. The Skyliner was a joy to use. After having to give up star gazing for a length of time, and my last scope being a Nexstar 6SE, I was looking for a replacement which would be light enough, cheap enough to get back into the hobby and comfortable to use.

Damian's review is not true. The telescope has a Strehl ratio of 0. One of the main values to look at when testing a refractor is the Strehl ratio.

Developed in the s, the Dobsonian-style telescope is an inexpensive solution for bright, detailed visual observing using a simple design. Dobson was well known for constructing large aperture reflecting telescopes capable of deep sky viewing, using low cost materials. These were often made with found materials, heavy cardboard tubes, recycled porthole glass, and plywood mounts. Dobson, who literally wrote the book on how and why to make amateur telescopes, encouraged other astronomers to assemble their own telescopes and taught workshops on telescope making.

With an 8-inch aperture, the Classic P Dobsonian is times brighter than the human eye!

David Shen, the founder of Sky-Watcher, started pursuing his interest in optics design and star observing when he was 26, working as a polishing technician at a research institute in Taiwan. It was a lovely summer night after work that the bright stars urged David to observe them with a telescope. After placing the telescope on top of the hood of his car, the view of the magnificent rings from the Saturn planet greatly moved David. That night was deeply engraved in David's memory since and constantly inspires him to live his dream:. But I hope that I could help more people gaze further.

This is a similar figure to the PV and measured exactly the same way. Limit value. Please enter your email address or telephone number here so we can contact you about the price match. The scope doesn't come fully collimated but its still usable right out of the box That thing has brilliant mirrors for the price. It's not really a product issue. Reflector Reflector. The P 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. Click here to make a request to customer service.

Telescope I bought this telescope despite living in a light polluted town, and having serious arthritis, which means I can not drive to a dark skies area. Please get in touch for more details about this. I had a ton of questions and all of them were answered before I even made my purchase, allowing me as a complete novice to choose the right scope for me.
