What type of telescope is a Dobsonian? A Dobsonian is a reflecting telescope (uses a mirror, not a lens) in the same design as a Newtonian telescope (concave collecting mirror is at the rear of the telescope tube, eyepiece is on the side of tube, up near the front).
Then, How do you photograph Saturn with a telescope?
To capture Jupiter and Saturn as sharp ‘points’ while using a tripod, use a shutter speed of up to a few seconds. More than this and the Earth’s rotation will smear out the planets and stars. If you are using a wide-angle lens, you can use a longer exposure.
Secondly, Are Dobsonian telescopes good? Dobsonian telescopes are incredibly good and are great for amateurs and professional astronomers alike. They are also very economical compared to other telescopes. … The benefit of this type of optical arrangement is the telescopes light gathering ability. The more light gathered, equals more fainter objects to be seen.
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.
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 you take great conjunction pictures?
Use a wide-angle (24mm) to short telephoto (85mm) lens to frame the scene and exposures of no more than a few seconds at ISO 200 to 400 with the lens at f/2.8 to f/4. The sky and horizon might be bright enough to allow a camera’s autoexposure and autofocus systems to work.
What planets really look like through a telescope?
In a moderate telescope Venus and Mercury will reveal their phases (a crescent shape) and Venus can even show hints of cloud details with a right filter. Neptune and Uranus will look like small, featureless, bluish or greenish disks through any telescope.
Why can’t I see anything through my telescope?
If you are unable to find objects while using your telescope, you will need to make sure the finderscope is aligned with the telescope. … Once the crosshairs are centered on the same object you are viewing through the telescope eyepiece, the alignment of the finderscope is done.

How do you use a Dobsonian?
What can you see with a 16 Dobsonian?
The 16″ Sky-Watcher Dobsonian SynScan is a very large aperture, precision engineered telescope that will allow you to easily find and enjoy night sky treasures like Saturn, Jupiter, and other planets in the solar system, plus a huge array of deep-sky objects including galaxies, star clusters, nebulae, and more.
What size Dobsonian should I get?
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.

Can exoplanets be seen?
Exoplanets are very hard to see directly with telescopes. They are hidden by the bright glare of the stars they orbit. So, astronomers use other ways to detect and study these distant planets. They search for exoplanets by looking at the effects these planets have on the stars they orbit.
Are exoplanets small?
Exoplanets come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. They can be hot enough to boil metal or locked in deep freeze. They can orbit their stars so tightly that a “year” lasts only a few days; they can orbit two suns at once.
Can a telescope see the flag on the moon?
Yes, the flag is still on the moon, but you can’t see it using a telescope. … The Hubble Space Telescope is only 2.4 meters in diameter – much too small! Resolving the larger lunar rover (which has a length of 3.1 meters) would still require a telescope 75 meters in diameter.
How do you use a red dot finder on a telescope?
To use the Finder, simply look through the sight tube and move your telescope until the red dot merges with the object. Make sure to keep both eyes open when sighting. Like all finderscopes, the Red Dot Finder must be properly aligned with the main telescope before use.
How do you use a telescope properly?
Manually point your telescope as best you can at the target, and then look through the eyepiece. Hopefully, the object will be in the field of view, but if it isn’t, use the slow motion control knobs or dials on your telescope’s mount to make adjustments until the target is in the center of the eyepiece.
What can you see with a 14 inch Dobsonian telescope?
The 14” telescope optical tube collapses down to just a little over 38”, allowing you to transport the scope in a majority of vehicles. The large 14” mirror delves deep into the universe, showing you thousands of objects from Saturn, Jupiter, & Mars to galaxies, nebulae and star clusters millions of light years away.
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.
