  2. Amateur astronomy - Wikipedia

    en.wikipedia.org/wiki/Amateur_astronomy

    An image of the Cat's Paw Nebula created combining the work of professional and amateur astronomers. The image is the combination of the 2.2-metre MPG/ESO telescope of the La Silla Observatory in Chile and a 0.4-meter amateur telescope. Amateur astronomers engage in many imaging techniques including film, DSLR, LRGB, and CCD astrophotography.

  3. Astrophotography - Wikipedia

    en.wikipedia.org/wiki/Astrophotography

    Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon ) was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography.

  4. Lucky imaging - Wikipedia

    en.wikipedia.org/wiki/Lucky_imaging

    Lucky image of M15 core. Lucky imaging (also called lucky exposures) is one form of speckle imaging used for astrophotography.Speckle imaging techniques use a high-speed camera with exposure times short enough (100 ms or less) so that the changes in the Earth's atmosphere during the exposure are minimal.

    The equipment used varies from webcams and basic security cameras to specialized video astronomy cameras. Recent growing interest in the video 'near-live' aspect of astronomy has brought about websites devoted purely to the practice [ 6 ] and forums for users of the equipment [ 7 ] [ 8 ] [ 9 ]

  9. Radio astronomy - Wikipedia

    en.wikipedia.org/wiki/Radio_astronomy

    Radio telescopes may need to be extremely large in order to receive signals with low signal-to-noise ratio. Also since angular resolution is a function of the diameter of the " objective " in proportion to the wavelength of the electromagnetic radiation being observed, radio telescopes have to be much larger in comparison to their optical ...
