Developed in the 1970s, the Dobsonian-style telescope is an inexpensive solution for bright, detailed visual observing using a simple design. The name ‘Dobsonian’ comes from the telescope’s inventor, John Dobson, a Vedanta monk who popularized sidewalk astronomy and dedicated his life to astronomy outreach. Dobson was well known for constructing large aperture reflecting telescopes capable of deep sky viewing, using low cost materials. These were often made with found materials, heavy cardboard tubes, recycled porthole glass, and plywood mounts.

Often referred to as ‘light buckets’, Dobsonians provide users with the highest possible aperture for their money when compared to telescopes of a similar size, such as Schmidt-Cassegrains or refractors. Developed in the 1970s, the Dobsonian-style telescope is an inexpensive solution for bright, detailed visual observing using a simple design. The name ‘Dobsonian’ comes from the telescope’s inventor, John Dobson, a Vedanta monk who popularized sidewalk astronomy, and dedicated his life to astronomy outreach. Dobson was well known for constructing large aperture reflecting telescopes capable of deep sky viewing, using low cost materials. These were often made with found materials, heavy cardboard tubes, recycled porthole glass, and plywood mounts. Dobson, who literally wrote the book on how and why to make amateur telescopes, encouraged other astronomers to assemble their own telescopes and taught workshops on telescope making.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan style=\"font-weight: 400;\" data-mce-fragment=\"1\"\u003eThe Flextube Dobsonian innovates on that original design, offering users the ability to collapse the optical tube using a proprietary truss-tube system while retaining its collimation. The optical tube uses a parabolic primary mirror, constructed of borosilicate, then polished and coated with our proprietary \u003cspan data-mce-fragment=\"1\"\u003eRadiant™ Aluminum Quartz (RAQ™)\u003c\/span\u003e, producing a remarkable 94% reflectivity. With a 12-inch aperture, the Flextube 300P Dobsonian collects 1840 times more light than the human eye! This simple yet effective design is perfect for visual observation of faint objects, such as nebulae, star clusters, and galaxies. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan style=\"font-weight: 400;\" data-mce-fragment=\"1\"\u003eSupporting the Flextube Dobsonian is more than just a simple rocker box. The base uses Teflon™ bearings for smooth, easy Azimuth slewing and a patented tension control handle to lock the telescope in place. Once locked on an object, the telescope can support both 1.25-inch eyepieces as well as the heavier 2-inch eyepieces, allowing you to use virtually any eyepiece on the market. All Flextube Dobsonians come with a slew of accessories, including: two 1.25-inch eyepieces, a 1.25-inch eyepiece adapter, a 2-inch eyepiece adapter, dust caps and a 8x50 finderscope.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan style=\"font-weight: 400;\" data-mce-fragment=\"1\"\u003eAt Sky-Watcher, we stay true to the traditional John Dobson design, while offering a fresh look for the 21st century.

Often referred to as ‘light buckets’, Dobsonians provide users with the highest possible aperture for their money when compared to telescopes of a similar size, such as Schmidt-Cassegrains or refractors. Developed in the 1970s, the Dobsonian-style telescope is an inexpensive solution for bright, detailed visual observing using a simple design. The name ‘Dobsonian’ comes from the telescope’s inventor, John Dobson, a Vedanta monk who popularized sidewalk astronomy and  dedicated his life to astronomy outreach. Dobson was well known for constructing large aperture reflecting telescopes capable of deep sky viewing, using low cost materials. These were often made with found materials, heavy cardboard tubes, recycled porthole glass, and plywood mounts. Dobson, who literally wrote the book on how and why to make amateur telescopes, encouraged other astronomers to assemble their own telescopes and taught workshops on telescope making.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe Classic Dobsonian uses a parabolic primary mirror design, constructed of borosilicate, then polished and coated with our proprietary \u003cspan data-mce-fragment=\"1\"\u003eRadiant™ Aluminum Quartz (RAQ™)\u003c\/span\u003e, producing a remarkable 94% reflectivity. With a 6-inch aperture, the Classic 150P Dobsonian is 460 times brighter than the human eye! This simple yet effective design is perfect for visual observation of faint objects, such as nebulae, star clusters, and galaxies. \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSupporting the Classic Dobsonian is more than just a simple rocker box. The base uses Teflon™ bearings for smooth, easy azimuth slewing and a patented tension control handle to lock the telescope in place. Once locked on an object, the telescope can support both 1.25-inch accessories as well as the heavier 2-inch eyepieces, allowing you to use virtually any eyepiece on the market. The Classic Dobsonian includes two 1.25-inch eyepieces, a 1.25-inch adapter, a 2-inch eyepiece adapter, dust caps and a 6x30 finderscope.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAt Sky-Watcher, we stay true to the traditional John Dobson design, using just two mirrors, a metal tube, and a simple rocker box. Although we love computerized telescopes, using a star chart to find objects by hand can be far more fulfilling and will improve your knowledge of the night sky.

This wavelength is critical for studying solar phenomena like prominences, filaments, sunspots, and solar flares in great detail. Unlike standard white-light telescopes, which capture the Sun's broad spectrum, Hα solar telescopes offer a window into specific solar activity in the chromosphere, a layer of the Sun's atmosphere located just above the photosphere.\u003c\/p\u003e\n\u003ch1 class=\"MsoNormal\"\u003eEtalon Filter Technology\u003c\/h1\u003e\n\u003cp\u003eAt the heart of most Hydrogen Alpha solar telescopes lies the etalon filter, a highly precise optical device that isolates the Hα wavelength from the rest of the Sun’s emitted light. An etalon is a type of interferometer, consisting of two parallel mirrors separated by a precise distance. The etalon works by reflecting light multiple times between the mirrors, selectively allowing only wavelengths that satisfy specific resonance conditions to pass through.\u003c\/p\u003e\n\u003cp\u003eIn the case of Hα solar telescopes, the etalon is designed to transmit light at the Hα wavelength while blocking all other wavelengths. The key to the etalon’s performance lies in its ability to tune the wavelength it transmits. This is achieved by adjusting the distance between the mirrors or by slightly tilting the etalon, which changes the interference conditions. This tunability is crucial because the Sun's emission at Hα can shift slightly due to Doppler effects as material moves across the Sun’s surface and atmosphere.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThere are two primary types of etalon filters used in solar telescopes: single etalon and double etalon systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSingle Etalon:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eA single etalon filter typically has a narrower bandwidth, providing high contrast for detailed solar observations but at the cost of limiting the field of view.
