    Telescope Stability Systems. I’ve got a nice Takahashi EM-10 mount. While its GOTO system is a bit quirky (an understatement), it sure is a nice and smooth mount. Its polar scope is also a real joy as in about 5 minutes I’m aligned well enough to image all night long. In fact, here’s a shot I took without any alignment over 100 minutes of ...

Observatory - Pointing Control | NASA

    https://www.nasa.gov/content/goddard/hubble-space-telescope-pointing-control-system/
    While operating in Earth orbit, the Hubble Space Telescope depends on a robust Pointing Control System to determine the direction in which it is pointing (called its attitude), to turn toward a celestial target, and to remain fixed on that target during observations. The Pointing Control System uses two sets of hardware: sensors and actuators.

    Regarding stability, to achieve high-contrast imaging for exoplanet science using a coronagraph instrument, systems must maintain wavefront stability to < 10 pm RMS over intervals of ~10 minutes during critical observations.

Equatorial Telescope Mounts | Uses, Best Practices & …

    https://astrobackyard.com/equatorial-telescope-mount/
    Because the Earth makes a full rotation on its axis every 24 hours, the night sky appears to slowly move throughout the night. For telescope observers and astrophotographers, this presents a challenge in terms of staying “locked on” a target. A basic deep-sky astrophotography setup using an equatorial telescope mount.

    Direct detection and characterization of extrasolar planets has become possible with powerful new coronagraphs on ground-based telescopes. Space telescopes with active optics and coronagraphs will expand the frontier to imaging Earth-sized planets in the habitable zones of nearby Sun-like stars. Currently, NASA is studying potential space missions to detect and …

    The precursor technology to these systems is the use of segmented aperture mirrors in ground-based observatories. 1 In these systems, manufacturing capabilities and gravity sag impose limits to the achievable size of individual mirrors. 2 The engineering effort to produce a deployable space telescope (DST) with a segmented aperture has ...
