Narrowband Modem
$100.37
High Quality Content by WIKIPEDIA articles In telecommunication, a narrowband modem is a modem whose modulated output signal has an essential frequency spectrum that is limited to that which can be wholly contained within, and faithfully transmitted through, a voice channel with a nominal 4 kHz bandwidth. Telecommunication is the transmission of messages, over significant distances, for the purpose of communication. In earlier times, telecommunications involved the use of visual signals, such as smoke, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded drumbeats, lungblown horns, or sent by loud whistles, for example. In the modern age of electricity and electronics, telecommunications has typically involved the use of electric means such as the telegraph, the telephone, and the teletype, the use of microwave communications, the use of fiber optics and their associated electronics, and/or the use of the Internet. The first breakthrough into modern electrical telecommunications came with the development of the telegraph during the 1830s and 1840s.

1.25 Orion Oxygen-III Extra-Narrowband Filter
$134.99
Photograph Nebulas in a New Light, Even With a Full Moon Oxygen-III (O-III) Extra-Narrowband Imaging Filter The O-III filter passes light at the 500.7nm wavelength (the Oxygen-III line) with very high 90 percent transmission and a bandpass of 7nm. It complements the Orion H-alpha (5587) and Sulfur-II (5579) extra-narrowband filters, which together allow advanced tricolor imaging of emission nebulas with the StarShoot Deep Space Monochrome CCD Imaging Camera or other monochrome CCD cameras. So if you're ready to go beyond RGB imaging and capture your favorite nebulas in a revealing new light - no matter how light-polluted your skies -- add our O-III (and S-II and H-alpha) Extra-Narrowband filter to your imaging arsenal! Includes protective plastic case.

2 Orion Extra-Narrowband Sulfur-II Filter
$359.99
Effectively blacken the background sky with extra-narrowband filters to produce striking, high-contrast astrophotography of emission nebulae. Orion's 2" Extra-Narrowband Sulfur-II Imaging Filter will do just that. It is ideal for use with monochrome CCD cameras like Orion's Parsec 8300M. It's one of a set of three filters designed to capture details of faint emission nebulae in monochrome astrophotography by creating high-contrast. These specialized line filters transmit only the specific wavelengths of light import in emission nebulae, while blocking out the rest. Orion's 2" Extra-Narrowband Sulfur-II Imaging Filter has a full-width half maximum (FWHM) bandpass of just 7nm, ensuring high-contrast images, even in heavily light-polluted or brightly moonlit skies. This filter can be used separately or in combination with a filter wheel for advanced tri-color astrophotography. Go beyond RGB imaging and capture your favorite nebulae in a revealing new light - no matter how light polluted your skies. Add Orion's 2" Extra-Narrowband Sulfur-II Imaging Filter and see the difference! Includes a protective plastic case.

2 Orion Extra Narrowband Filter Set
$969.99
Orion's 2" Extra Narrowband Hydrogen-Alpha, Oxygen-III, and Sulfur-II filters are designed to enhance the contrast of emission nebulae in monochrome astrophotography. They are perfect for using with a monochrome CCD camera like Orion's Parsec 8300M Astronomical Imaging Camera. Imaging with extra-narrowband filters is the latest technique used by amateur astronomers for producing striking, high-contrast color CCD astrophotos of emission nebulae. These specialized 'line' filters transmit only the specific wavelengths of light important in these nebulae, while blocking out all the rest. They blacken the background sky to produce high-contrast images, even in heavily light-polluted or brightly moonlit skies. The filters can be used separately or in combination with a filter wheel for advanced tri-color astrophotography. Capture your favorite nebulae in a revealing new light - no matter how light-polluted your skies. Add Orion's 2" Extra Narrowband CCD Filters to your imaging repertoire!
