Each optical surface is tested up to 29 times as it passes through its many processes of being turned from a blank piece of glass to a highly accurate figured mirror or lens. Below is our selection of telescope mirrors available to purchase and a brief description of each grade's qualities.
Aberration theory and prototype mirror experiment presented at the 2010 - 2011 alt - az initiative hawaii conference on light bucket astronomy 2011 figures of merit for light bucket mirrors.
In its alt/az configuration, it is considerably more compact than its german equatorial counterpart, allowing a larger telescope to fit in a smaller enclosure. Unlike german equatorial mounts, there are no meridian flips to deal with, and no large protruding counterweights to create a dangerous hazard in a public observatory.
(57) summary the fully automated telescope system (10) is fully operational in both alt-az and polar configurations. In either configuration, the telescope (10) aligns itself in a spherical coordinate system after a simple initialization procedure. At that time, the lens barrel (12) points first to the north and then to the user's horizon.
Finally, any telescope with a lens or mirror larger than 10 inches is “large.
Upgrade your small telescope/spotter to a tabletop dobsonian/alt-az telescope: this instructable details making a mount to repurpose a spotting scope or small telescope that would normally mount on a tripod or equatorial mount onto a small alt-az or dobsonian mount.

The alt-az initiative is a catalyst for the development of low cost, lightweight, modest aperture (2 meters and less) alt-az research telescopes. Such telescopes, especially when automated and networked, can be cost-effective tools for dedicated research programs including low and high resolution fiber fed spectroscopy as well as optical, near infrared, and high speed photometry.
Because scopex is an initiative of the assa telescope making class, the presence of the atm community and their handiwork is a fundamentally important component of the exposition.

Sporting a distinctive large aperture and deep light bucket, the explore scientific firstlight 203mm f/6 alt-az dobsonian telescope gives users powerful performance at a reasonable price. Its large parabolic primary and smaller secondary mirrors are made from low-expansion glass to eliminate distortion across the entire field of view, especially at the edges, while allowing sharp resolution of star clusters and nebulae that smaller apertures cannot achieve.

The initiative's first alt-az technical demonstration telescope, the cal poly 18, recently saw first key is the development of lightweight, low cost primary mirrors.
For refractors, that means a solid mount on a steady tripod that lets you tilt the scope up and down and swivel it left and right. The scope should move smoothly, and it should stop when you stop pushing without bouncing back and without wiggling.
Refractor telescopes are excellent for lunar and planetary viewing as they offer very crisp and sharp images. Reflectors uses superb quality mirror set as the standard for sky-watcher.
The altitude-azimuth mount or alt-az mount is named because of its descriptive range of movement. The up-down movement of any device changes its altitude, and the right to left movement is what astronomers call azimuth. The simple camera tripod stand is the perfect example of an alt-az mount.
Zhumell z114 portable alt-az reflector the groundbreaking z series dobsonians from zhumell have been a revelation in the world of amateur astronomy. Now with the compact z114, you can enjoy all the benefits of zhumell's unparalleled quality in a tabletop dobsonian with excellent portability.

Future technical initiatives and technical demonstration telescopes are outlined. Two books, small telescope and astronomical research and the alt-az initiative: telescope, mirror, and engineering developments, based on these meetings, initiatives, and the demonstration telescope, are now available.
An alt-az mount moves in altitude (up and down) on a horizontal axis and in azimuth (left and right) on a vertical axis like a gun turret on a tank. By comparison, an equatorial mount is essentially an alt-az mount that is tilted to match your latitude, allowing a telescope to track the stars with the addition of a simple clock drive.
The thirty meter telescope (tmt) is a powerful tool to accelerate scientific understanding of the universe of all humankind. It will advance the world's knowledge across a vast span of time from the first galaxies that formed in the universe to the planets that orbit nearby stars in our own milky way galaxy that might harbor life.
Buddy martin: most mirrors at home, say bathroom mirrors, have the reflective coating on the back of the mirror. But for a telescope mirror, you can’t afford to let the light go through the glass. We usually think of glass as an optical material, because light goes through glass, and we make lenses out of glass.
The telescope adopts an alt-az mount system and a master-collimator to achieve precise pointing accuracy. The radio signal collected with the main- and sub- reflectors is guided to the receiver cabin with the common beam-guide optics, which consists of a plane mirror, a pair of ellipsoidal mirrors, and a rotatable plane mirror.
The problem of field rotation in alt -az telescopes was solved by mounting cameras ( and other instruments) on a computer-controlled, motorized derotator. Most large alt-az telescopes have a small, flat tertiary mirrorthat can be switched 180 degrees to deflect.

Altitude-azimuth (alt-az) mounts reduce the size of the required telescope enclosure. An 8-m alt-az telescope can fit into the same size enclosure as a 4-m equatorial telescope. An alt-az telescope requires computer-controlled pointing and tracking on two axes, whereas the traditional equatorial mount requires tracking on only a single axis.
Astelco has manufactured either variants of the classical alt-az/equatorial mount versions or complete special telescope systems, like coudé telescopes, coelostats and siderostats, lgs (laser guide star) systems for ao applications, seeing measurement telesopes (dimm, slodar) with enclosure and tower, solar telescopes, and wide-field telescope arrays.

The observatory of the subaru telescope was officially established in april 1997, following the completion of its base facility building in hilo, hawaii. Subaru telescope can refer to the telescope itself or the entire observatory organization.
With an alt-az mount, an astronomer had to move the telescope along two axes simultaneously to keep an object in view, but this was compensated by its relatively compact size. Hadley's telescope was tested by two english astronomers in 1722 by observing saturn.
The oldest and simplest design is the manually adjusted altitude-azimuth mount, often referred to as an alt-az. These work like the pan-and-tilt heads on photo tripods, moving the scope up-down (in altitude) and left-right (in azimuth).
Unistellar’s debut product is very different to a traditional optical telescope. The instrument uses an extremely sensitive electronic sensor at the focus of a 450mm focal length f/4 mirror on a self-aligning computerised alt-az mount.
The spaceprobe 3 alt-az telescope is an entry level newtonian reflector type telescope on an alt-azimuth mount. If you want the quick summary of this page, the spaceprobe 3 alt-az is a great entry level telescope if your budget allows only around $120. It will give you an honest and true start in astronomy at about the lowest cost possible.
Accordingly, alt-az telescope configurations must “stop the sky” in software when tracking a celestial object. In contrast to a polar or equatorial mounting, which may be driven in one axis only, at a constant rate, both axes of an alt-az telescope mount must be driven at rates that vary over a wide dynamic range.
Focal length is the distance between the primary mirror or lens and where the this equatorial mount is more complex than an alt-azimuth mount as it moves.
An 8-m alt-az telescope can fit into the same size enclosure as a 4-m equatorial telescope. An alt-az telescope requires computer controlled pointing and tracking on two axes (whereas the traditional mount requires tracking on only a single axis). The hale telescope is the largest equatorial telescope ever built.
New calculations by schauer show that a previously proposed facility, a liquid mirror telescope that would operate from the surface of the moon, could study these stars. Proposed in 2008 by a team led by roger angel of the university of arizona, this facility was called the lunar liquid-mirror telescope (llmt).
