No telescope type has changed the hobby quite as much as the Dobsonian. Before the popularization of the Dobsonian by John Dobson, the vast majority of amateur telescopes consisted of small telescopes with primitive mechanics - barely enough to see the polar caps of Mars or the rings of Saturn. Larger telescopes, such as the Schmidt-Cassegrain were reserved for the wealthy.\u003c\/p\u003e\n\u003cp\u003eThe ingenious combination of simple yet effective mechanisms with the greatest possible opening gives the Dobsonian telescope a unique triumphant march around the world. Nowhere do you get as much light for your money like a good Dobson. Disassembly of the scope without tools ensures a trouble-free transport of this great scope even in small cars. The entire structure has been optimized for maximum stiffness with minimal weight. The combination of high altitude bearings with optimized aluminum structures allows fine adjustment flows at high magnifications.\u003c\/p\u003e\n\u003cp\u003eThe ideal workhorse for the deep sky observers. A 406mm mirror collects more than 2,400 times as much light as the naked eye. Details on planets and deep sky objects will be visible even for inexperienced observers. Bright star clusters are resolved to the core, and the sight of the terminator on the moon is an unforgettable experience.\u003c\/p\u003e\n\u003cp\u003eIncludes 2\" focuser with helical gearing and 10:1 reduction; LED Red Dot Finder, collimation assist tool; soft light baffle and two radial main mirror fan for fast temperature equilibrium.\u003c\/p\u003e\n\u003cp\u003eThe scope is ready for the use with our optional \u003ca href=\"https:\/\/telescopescanada.ca\/collections\/accessories\/products\/hr-variable-coma-corrector-2-inch-hrcc02-00\"\u003ecoma corrector\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003e\u003ca href=\"https:\/\/www.stelvision.com\/en\/telescope-simulator\/visu.php?D=406\u0026amp;F=1826\u0026amp;FD=4.6153846153846\u0026amp;type_choix=manu\u0026amp;f_1=25\u0026amp;f_2=10\u0026amp;f_3=\u0026amp;f_4=\u0026amp;f_5=\u0026amp;Barlow=oui\u0026amp;champ_nom=50\u0026amp;champ_alt=\u0026amp;cibles=lune%2Csaturne%2Cpleiades\u0026amp;simu_personnalisee=Simulate\" target=\"_blank\"\u003e\u003cspan\u003eSimulated views with 25mm and 10mm eyepieces, with and without a 2x Barlow Lens\u003c\/span\u003e\u003c\/a\u003e\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"30%\"\u003eItem Number\u003c\/td\u003e\n\u003ctd width=\"70%\"\u003eDOB1645–00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSecondary Obstruction\u003c\/td\u003e\n\u003ctd\u003e25%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Mirror Diameter\u003c\/td\u003e\n\u003ctd\u003e406mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSecondary Mirror Diameter (M.A.)\u003c\/td\u003e\n\u003ctd\u003e72mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e1826mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Ratio\u003c\/td\u003e\n\u003ctd\u003ef\/4.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Mirror Weight\u003c\/td\u003e\n\u003ctd\u003e66.1 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRocker Box Weight\u003c\/td\u003e\n\u003ctd\u003e22 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Weight\u003c\/td\u003e\n\u003ctd\u003e88.1 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":28276520714320,"sku":"DOB1645-01","price":5184.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0224\/6770\/6960\/products\/explore-scientific-telescope-explore-scientific-generation-ii-16-inch-truss-tube-dobsonian-telescope-dob1645-00-11083467751504.jpg?v=1668371559"},{"product_id":"explore-scientific-102mm-achromat-refractor-telescope-optical-tube-assembly-with-accessories-dar102065-01","title":"Explore Scientific 102mm Achromat Refractor Telescope - DAR102065-02","description":"\u003cp data-mce-fragment=\"1\"\u003eThe Explore Scientific AR Air-Spaced Doublet Series telescopes are classic air-spaced, crown-and-flint, doublet achromatic f\/6.5 refractors with a superior-class optical figure.

The 500mm mirror collects 5100 times more light than the naked eye. Details on planets and deep sky objects will be visible even for inexperienced observers. Bright star clusters are resolved to the core, and the sight of the terminator on the moon is an unforgettable experience.\u003c\/p\u003e\n\u003cp appify_fntsize=\"14px\"\u003eThe fast 20\" f3.6 main mirror as well as the large 120mm secondary mirror are made of high quality quartz material, so the cooling time is reduced to a minimum and this Dobsonian is quickly ready for use. Every main mirror is delivered with an individual optical test certificate, which guarantees the highest capacity. A laser engraved center mark of the main mirror allows easy adjustment. The optical surface has a high-quality aluminum coating with 94% reflectivity and an extremely resistant quartz protection layer. The mirror overcomes frequently occurring dew fogging and cleanups without damage and guarantees a long service life.\u003c\/p\u003e\n\u003cp appify_fntsize=\"14px\"\u003eNo telescope type has changed the hobby quite as much as the Dobsonian. Before the introduction of the Dobsonian by John Dobson, the vast majority of amateur telescopes consisted of small telescopes with primitive mechanics - barely enough to see the polar caps of Mars or the rings of Saturn. Larger telescopes, such as the Schmidt-Cassegrain were reserved for the wealthy. The ingenious combination of simple yet effective mechanisms with the greatest possible opening gives the Dobsonian telescope a unique triumphant march around the world. Nowhere do you get as much light for your money like a good Dobson. Disassembly of the scope without tools ensures a trouble-free transport of this great scope even in small cars. The entire structure has been optimized for maximum stiffness with minimal weight. The combination of high altitude bearings with optimized aluminum structures allows fine adjustment flows at high magnifications.\u003c\/p\u003e\n\u003cp appify_fntsize=\"14px\"\u003eA complete redesign of this Dobsonian was necessary to ensure the significantly increased requirements to stiffness and load bearing capacity of the optical components. All connections of the tube structure were made in the TIG welding process and no rivets and screws were used. This has made it possible for us to produce this 20\" light weight Dobsonian so unbelievably stiff in spite of the low weight - a noticeably good quality which is begging you to take one home. The production of almost all mechanical components is carried out by our partners in Hungary and the final assembly of the optics and subsequent quality control takes place in Rhede, Germany. \u003c\/p\u003e\n\u003cp appify_fntsize=\"14px\"\u003eA second 40° displaced installed mounting plate with a viewfinder shoe allows the rotation of the tube top in combination for a favorable position of the viewfinder tube or the mounting of an additional TELRAD viewfinder. The 6 supporting feet underneath the rocker box offers perfect stability and guarantees smooth tracking in azimuth. Four smaller fans are installed in the side of the mirror box as well as a large fan installed under the main mirror. This allows an even quicker adaptation to the ambient temperature and reduces the tube seeing (boundary layer removal).

With small pixels and high QE, you do not need a big guide scope. Smaller pixels can detect the guide error in a shorter focal length scope. And, when the focal length is reduced, the FOV becomes larger, so it is easier to find bright guide stars. QHYCCD's new Mini Guide scope is based on just this idea. The QHY5L-II has 74% high QE, 4e- readout noise and small 3.75um pixels.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis camera is idea for a short focal length guide scope. The MiniGuideScope is a 30mm f\/4.3 (130mm FL) ultra-small telescope. It has no complex focal adjust system. Just rotate the front of the OTA and it provides fine focal adjustment. Once focus is achieved, the tube can be locked into position and there is not need to focus again unless the system is moved. The MiniGuideScope provides pin-point star images as sharp as any lens in the industry.\u003c\/span\u003e \u003c\/p\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable cellspacing=\"0\" cellpadding=\"5\" border=\"1\" bgcolor=\"#ffffff\" align=\"center\" microsoft=\"\" bordercolorlight=\"#c0c0c0\" bordercolordark=\"#808080\"\u003e\n\u003ctbody\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd width=\"116\"\u003e\n\u003cdiv class=\"wpmd\"\u003e\u003cspan\u003eDiameter\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003e30mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd width=\"116\"\u003e\n\u003cdiv class=\"wpmd\"\u003e\u003cspan\u003eFocal Length\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003e130mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd width=\"116\"\u003e\n\u003cdiv class=\"wpmd\"\u003e\u003cspan\u003eAperture \u003c\/span\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003e1:4.3\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd width=\"116\"\u003e\n\u003cdiv class=\"wpmd\"\u003e\u003cspan\u003eObject Lens Type\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eDoublet\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd width=\"116\"\u003e\n\u003cdiv class=\"wpmd\"\u003e\u003cspan\u003eFocus System\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eFront Side Focuser\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd width=\"116\"\u003e\n\u003cdiv class=\"wpmd\"\u003e\u003cspan\u003eFocus Locker\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eYes\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eCamera Interface\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eC\/CS Mount\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eCompatible Cameras\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eQHY5II and QHY5III series\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eAnti-Scatter Light Matte Paint\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eYes, Internal painted\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eWeight (OTA only)\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003e111g\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eTelescope Connector\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eOptional Standard ViewFinder Scope Connector with Tripod Screw Thread  \u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eDiameter of the OAT \u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003e31.6mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eFocus Adjustable Range\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cspan\u003eInf. to 1.5 meter\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"QHYCCD","offers":[{"title":"Default Title","offer_id":28284287811664,"sku":"QHYMINIGUIDERSCOPEWITHMOUNT","price":174.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0224\/6770\/6960\/files\/qhyccd-guide-scope-qhyccd-30mm-f-4-3-telescope-miniguidescope-with-mount-40385030226139.jpg?v=1703883368"},{"product_id":"optolong-l-enhance-dual-bandpass-filter-h-alpha-o2-2-inch","title":"Optolong L-eNhance Dual Narrowband Filter (H-Alpha and H-Beta\/O-III)","description":"\u003cp\u003eThe relentless spread of urbanization and its associated light pollution have become a growing problem for all amateurs and astro photographers.

and planetary images. \u003c\/span\u003eThis device dramatically reduces the prismatic smearing caused by the passage of the light through our atmosphere and allows planetary images to be taken which show noticeably finer detail.\u003c\/p\u003e\n\u003cp\u003eCommercial ADCs are relatively new. Their significant benefits, however, justify more astronomers knowing about them. As well as being an advantage to imagers, they can also help visual planetary observers, increasing the amount of surface detail seen through the eyepiece.\u003c\/p\u003e\n\u003ch4\u003eWhy you would use an ADC?\u003c\/h4\u003e\n\u003cp\u003eLight from any star or planet that enters our atmosphere at an angle will suffer refraction effects which bend to light to a slightly steeper angle. This refraction effect makes the object appear higher in the sky than if the atmosphere wasn't there. The degree of refraction depends to a small degree on various things like temperature, humidity, observers and height above sea level, but does increases strongly with decreasing altitude of the object - for example, the image of the sun at sunset can actually be elevated by over 0.5°, which is slightly more than one solar diameter.\u003c\/p\u003e\n\u003cp\u003e Like most optical media the refractive (bending) power of the atmosphere is actually dependent on the wavelength of light. This is called optical dispersion. Atmospheric dispersion means that actually the degree of 'lift' that the refraction causes depends not only on the angle of the light, but also the colour of that light. Atmospheric dispersion spreads the light from any point source into a vertical spectrum of colours whose length increases the lower the object is in the sky.\u003c\/p\u003e\n\u003cp\u003eThe diagram of viewing Saturn illustrates this dispersion effect as light enters the atmosphere and also the lifted elevation of the image. The lift is wavelength dependent and hence the image is separated into different colours.

Though the second window for the H-alpha-line is not intended for visual observing, it is important, if the filter is used with an electronic device. All annoying, scattered light from other wavelength sources, including local artificial light pollution, is reliably filtered out.

The high transmission of our optical glass filters means that enough light is available to allow successful visual observations with telescopes beginning at 2\" (50mm) aperture. Our Astronomik filters are optimized for use with telescope focal length f \/ ratios of f\/4 to f\/15. Transmission losses and chromatic distortions, which arise with other filters, only occur with Astronomik filters when extremely bright aperture ratios of 1:2 and more come into play. Another major advantage of our Astronomik UHC filter is the high optical quality of the filter glass.

You want as much signal as possible so the filter should have the highest transmission possible with a wide spectral Band-pass. This combination provides the greatest sensitivity and gives you the highest photon counts on your pixels. While the high transmission level is a great aspect of the new Astronomik Luminance filters, not all optical instruments or additional optical elements like correctors, field-flatteners or reducers, have perfect colour correction so it can be the width of the spectral band pass of  the Luminance filter that can cause problems. A band pass that is too wide will allow the transmission of incompletely focused light (Chromatic aberration), making stars appear soft or bloated. In such cases image processing can become difficult, so having a slightly narrowed spectral window in your Luminance filter can reduce or eliminate this damaging effect.\u003c\/p\u003e\n\u003cdiv class=\"ic_wrapper ic_myCarousel\" id=\"ic_63597013_wrapper\"\u003e\n\u003cdiv class=\"infiniteCarousel ic_peek_padding\" id=\"ic_63597013\"\u003e\n\u003cdiv class=\"ic_tray\"\u003e\n\u003cdiv class=\"infiniteCarousel_item\" id=\"ic_63597013_2\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"infiniteCarousel_item\" id=\"ic_63597013_3\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"infiniteCarousel_item\" id=\"ic_63597013_4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"infiniteCarousel_item\" id=\"ic_63597013_5\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"infiniteCarousel_item\" id=\"ic_63597013_0\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"infiniteCarousel_item\" id=\"ic_63597013_1\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ic_left_nav\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"ic_right_nav\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"ic_controls\" id=\"ic_controls_63597013\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ccanvas height=\"30\" id=\"ic_canvas_63597013\" width=\"30\"\u003e\u003c\/canvas\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ic_thumbnail_tray\" id=\"ic_63597013_thumbnail_tray\"\u003e\n\u003cdiv class=\"ic_thumbnails\"\u003e\n\u003cdiv class=\"ic_button ic_active\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ic_button\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ic_button\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003eTo give you all the tools to gather the best data possible\u003cspan\u003e \u003cstrong\u003eAstronomik\u003c\/strong\u003e\u003c\/span\u003e\u003cstrong\u003e has expanded their line of Luminance filters\u003c\/strong\u003e: Now you can select a Luminance filter perfectly matched to the kind of telescope you use, to get the highest signal and sharpest image for the Luminance channel!\u003cbr\u003eDepending on the color correction of your scope you may use a wider spectral window for the Luminance data.
