Dobsonian Mirror Edge Support Calculator

    http://www.cruxis.com/scope/mirroredgecalculator.htm
    This tool can help you to choose or validate the lateral support of your telescope mirror - the part of the mirror cell that supports the mirror when it's pointing to the horizon. Just plug in the dimensions of your telescope mirror, select a support configuration, and compute the mirror surface deformation.

lateral supports - Astrosurf

    Those lateral supports were improved thanks in particular to the work of Luc Arnold, professional at the OHP, in order to allow a still better support of the mirror in its mirror cell wherever we aim the scope at the sky. These supports replace the sling without deformation or generation of astigmatism on the mirror.

    Many telescopes have mirror mounts that are less than ideal. Some hold the mirror in place with clips that project over its surface and introduce image-harming diffraction effects. Others have adjustments that require tools or are so frustrating that observers rarely … Continue reading "A Simple Double-Plate Mirror Cell for Your Reflector"

    Mirror support system of astronomical telescope is composed of axial support and lateral support. In traditional telescope, because the contribution of lateral support to surface distortion is less than axial support, there are usually few lateral support methods such as lever counterweight, hydrostatic pressure and steel strap in the past.Cited by: 3

Nondistorting lateral edge support of large telescope mirrors

    https://www.osapublishing.org/ao/abstract.cfm?uri=ao-33-7-1198
    Simply by push-pull shear action at their outer edge, large circular telescope mirrors can be laterally supported free from bending distortion, if the upright mirror is kept in balance by a cosine distribution of weak axial forces applied at its outer rim and possibly also at the central hole. The flexure-induced comalike wave-front aberration of a thin 8-m meniscus mirror was reduced to an ...

Mirror clip diffraction can be seen as broad swaths of light emanating radially from a bright planet or star, unlike spider vane diffraction, which is a thin spike. ...

TMT International Observatory

    The secondary mirror reflects the light from the f/1 primary mirror and converts it to an f/15 beam for the science instruments. The mirror is 3.1 meters (10 feet) in diameter, as large as the primary mirrors of many telescopes currently in use. It will be mounted in a steel mirror cell that contains the axial and lateral supports for the mirror.

UL16 - Hubble Optics

    http://hubbleoptics.com/UL16.html
    Engineered Mirror Support: The UL16 has an extensively modeled and optimized 6-point flotation system that provides more than adequate support for the sandwich mirror. The three-point collimation system is completely independent from the sling lateral support.
