Is A Dobsonian Telescope A Reflector?
Is a Dobsonian telescope a reflector? Technically, a Dobsonian is a reflector itself, but it just has a different mount than your typical Newtonian reflector. Whilst a Dobsonian uses a Alt/az (altazimuth) mount, normal reflectors will use an equatorial mount.
Are Dobsonian telescopes the best?
Dobsonian telescopes are incredibly good and are great for amateurs and professional astronomers alike. They are also very economical compared to other telescopes. The optical part of the telescope or OTA (Optical Tube Assembly) is the same as a Newtonian reflector telescope.
Are Dobsonian telescopes good for viewing planets?
Are Dobsonian telescopes good for viewing planets? Yes, Dobsonians are good for viewing planets. With a 6″ Dobsonian, you'll get to see the polar caps on Mars, the rings of Saturn, and the moons and bands of Jupiter providing you ave the right viewing conditions.
Is a Dobsonian telescope good for beginners?
A Dobsonian is intuitive and easy to operate, which is another reason why it makes such an excellent telescope for beginners. A Dobsonian mount is so easy to set up and use, it feels like second nature. All a person needs to do is grab the scope and move it in the right direction.
Which is better Dobsonian or Newtonian?
This makes the Dobsonian more robust, and better for carrying around without worry of damaging your telescope. Dobsonian tubes are twice the length of some standard Newtonians, as a Dob uses a flat secondary mirror as opposed to curved.

How good is an 8 inch Dobsonian 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.

Orion 8945 SkyQuest XT8 Classic Dobsonian Telescope. Our overall top pick for best Dobsonian telescope. The Orion SkyQuest XT8 is our #1 “all around” Dobsonian recommendation. It's versatile and affordable, with a powerful 8″ (203mm) primary mirror, while still being portable enough to fit in your vehicle.
Can you take pictures with a Dobsonian telescope?
To take pictures through a Dobsonian telescope, you must carefully align the camera lens of your smartphone or point-and-shoot camera with the eyepiece of the telescope. The magnification of the eyepiece inserted into the telescope focus drawtube will determine the size of the object in your image.
Can Dobsonian telescopes track?
Dobsonian telescopes offer big thin mirrors with stable, inexpensive altazimuth mounts. Motorizing a dobsonian adds automatic tracking and finding capabilities. With the object remaining centered in the eyepiece, you enjoy the relaxing view. In addition, you can use higher magnifications to bring out detail.
What telescope can see the farthest?

What can you see with a 4.5 inch reflector telescope?
In addition to good views of the moon and all eight planets, a 4.5-inch reflector will show all of the Messier objects and hundreds more galaxies, nebulae and star clusters. That is assuming the skies are moonless, clear and you're away from urban areas.
Are Dobsonian telescopes Newtonian?
A Dobsonian telescope is an altazimuth-mounted Newtonian telescope design popularized by John Dobson in 1965 and credited with vastly increasing the size of telescopes available to amateur astronomers.
How do I choose a Dobsonian telescope?
As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. Dobsonian telescopes, which are reflectors with a simple mount, provide lots of aperture at relatively low cost. A larger aperture lets you see fainter objects and finer detail than a smaller one can.
How does a Dobsonian mount 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.
What can you see with a 20 Dobsonian telescope?
The massive mirror in this Dob allow much more light to be reflected into the eyepiece than a typical telescope.
