Can you put a Dobsonian on an equatorial mount?
A Dob on a platform can perform as well as a reflector on an EQ mount, well, for an hour or so anyway, for a fraction of the cost of an appropriately sized traditional EQ mount. The platforms are also much lighter and easier to transport than a big EQ mount and tripod.
What kind of mount is a Dobsonian?
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 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.
Can Dobsonian telescopes track?
However the simple manual Dobsonian mounting does have its disadvantages, particularly when observing at higher powers. The lack of tracking and the constant necessity to manually move the telescope to counter sidereal rotation can limit the effectiveness of observing at higher magnifications.
Can you mount a Dobsonian telescope on a tripod?
The strength, the value of the dobsonian mount is that it is low cost and very very stable. To get that in a tripod would cost a LOT more and would likely be fairly heavy.
Are Dobsonian telescopes hard to use?
Dobsonian telescopes are designed to be simple, easy to use and gather as much light as possible. Because of this robust simplicity, they are very economical and popular with astronomers of all levels of ability.
Can a Dobsonian telescope track stars?
No. If by “Dobsonian” you mean an alt-az mount, long exposures are not possible. Even if the tracking mount keeps the object in the centre, the image will rotate in the field of view. This would create star trails in a long-exposure image, worse at the edge of the FOV.
Can you use any tripod for a telescope?
Can you use a camera tripod for a telescope? You can fit a telescope to a camera tripod with a suitable adapter plate and head to which you can secure the scope. Most camera tripods will have a 1/4″ adapter plate into which you can screw a scope dovetail mount.
How do you build a Dobsonian telescope?
BUILDING a DOBSONIAN TELESCOPE MOUNT 1 Cutting The Bearings.#N#For this job you want a nearly perfect circle. I used a router and made an arm out of quarter… 2 Applying Laminate & Finishing.#N#I was lucky. Apparently I got the last bit of Ebony Star laminate (recommended by… More
Is the plywood DOB Smithsonian Mount easy to build?
The plywood Dobsonian mount is simple to build and very functional. In this section we will show you how to build a complete Dobsonian Telescope. The sample we will build is a 6-inch f/7.5, however the plans can be scaled down to 4-inch scopes and up to 10- or 12-inch scopes of various focal ratios.
Where does the Dobsonian sit?
Our Dobsonian sits in the garden at dusk cooling down for the nights observing. The yellow Optical Tube Assembly is a 6-inch f/7.5 Newtonian.
What is a DOB Smithsonian telescope?
A Dobsonian Telescope is a optically a Newtonian Reflector mounted on a Alt-Az mount with a low and stable center of gravity and Teflon-Laminate bearings. It was popularized by John Dobson of the San Francisco Sidewalk Astronomers, who is also an honorary member of the Springfield Telescope Makers.
