Is Dobsonian a Newtonian?
Is Dobsonian a Newtonian?
Dobsonian mounted telescopes are almost always Newtonian due to the Newt’s ideal placement of the eyepiece. A Dobsonian mount does not track the stars as they move in the sky, so it’s not suitable for some applications but it’s a great “looking around” mount and is really easy to use.
What is the difference between Dobsonian and Newtonian?
The answer is that Dobsonian and a Newtonian can actually be the same thing. A Newtonian refers to the telescope optics, whereas a Dobsonian refers to Newtonian telescope with some specific features like an altazimuth mount and often thin mirrors. A telescope can be a Newtonian and also a Dobsonian at the same time.
What is a Dobsonian good for?
Good “Deep Sky” telescope: The Dobsonian design of maximized objective diameter combined with portability makes the design ideal for observing dim star clusters, nebulae, and galaxies (deep sky objects), an activity that requires large objectives and travel to dark sky locations.
How do you use a Dobsonian?
Terms Defined. Alt-Azimuth (Alt-Az) Mount – What this term describes is no more than a mount able to move up, down, and side-to-side with ease. Due to the varying sizes of Dobsonians, these can be small or quite bulky to support a larger telescope.
What can you see with a 12 inch telescope?
12-inch Telescopes offer exceptional resolution for their size. They can resolve double stars at . 38 arcseconds and can be magnified up to 610 times the human eye. 12″ Optical tubes also make exceptional light gatherers by allowing an observer to see 16.2 magnitude stars!
What is the difference between a Dobsonian and a Newtonian telescope?
A Dobsonian can be a Newtonian and vice versa – they are not always mutually exclusive. Here’s why. The term Newtonian is referring to the optics of the telescope. The term Dobsonian is referencing specific features e.g. an Alt-Azimuth Mount, Thin Mirrors etc of a Newtonian Telescope.
What’s the difference between a DOB and a Newtonian?
An 8″ Dob is an 8″ Newtonian. Dobsonian is the mount. Newtonian is the telescope. Are you trying to compare a Dob mount to a German Equatorial Mount?
What are the characteristics of the Dobsonian design?
The Dobsonian design has the following characteristics: Altazimuth mount: An equatorial telescope mount with clock drive was left out of the design. Equatorial mounts tend to be massive (less portable), expensive, complicated, and have the characteristics of putting the eyepiece of Newtonian telescopes in very hard to access positions.
What is a DOB Smithsonian telescope?
It is based on the design of canons that were used in wars. You can visit this website for the anatomy of a Dobsonian telescope. The Dobsonian telescope works in basically the same way as the Newtonian telescope, but with minor adjustments in the basic materials used.
