A popular altazimuth
mount is the sturdy, boxy Dobsonian design.
In the 1917 May Journal Ainslie wrote a useful three page paper (37) entitled: Notes from the Instrument Committee--On the Choice of a Telescope in which he explained the relative advantages and disadvantages of reflectors, refractors, equatorial mounts and altazimuth
There is a plaque on the tube to testify to this, and that instrument was originally tripod mounted as an altazimuth
system, only being converted onto a modern equatorial mount in the 1970s.
* Many of today's telescopes have motor-driven altazimuth
mounts that keep them pointed at celestial objects as they move from east to west across the sky.
variation that's popular on Newtonian reflectors of all sizes (from $200 starter scopes to 36-inch monsters) is the Dobsonian mount.
The word astrolabe is from the Greek for "star taker." Most varieties have the same basics: a sighting device, a movable star map in the form of a metal network including a finely scaled zodiac ring; a flat, stereographic projection of the sky's altazimuth
coordinate grid from horizon to zenith; and a finely divided circular scale of hours around the outside.
We were looking for complete telescopes of at least 70-millimeters aperture, mated to simple, sturdy, easy-to-use altazimuth
Meade's Infinity 90mm Altazimuth
Refractor has enough aperture to produce satisfying views of the Sun, Moon, and planets, as well as bright deep-sky objects and double stars.
Superficially, the two have much in common--both are basic 5-inch Newtonian reflectors on altazimuth
If you want to take one of these telescopes along for casual observing on a weekend camping trip, you might want a mounting as simple (and portable) as a heavy-duty photographic tripod fitted with a lightweight altazimuth
A 1998 follow-up study using the Russian 6-meter Large Altazimuth
Telescope found magnitudes, diameters, separations, morphological types, configurations, and radial velocities.
Like Chuck, Art was looking for a way to improve on the conventional altazimuth
