One of these is the use of the Sony ICX825AQA CCD sensor.\u003c\/p\u003e\n\u003cp\u003eThe MallinCam StarVision camera is the result! The sensor used in the StarVision camera is 11 mm measured diagonally compared with the 8 mm sensor in the Xterminator, thus providing a wider field of view, which is desirable for larger objects. In addition, this sensor is capable of producing pinpoint stars with zero star artifacts and zero amplifier glow. This camera can be used both in light polluted urban environments or at dark sky sites. It will excel at outreach events where MallinCam has been leading the market with its full line of video astronomy cameras for live applications. And, there is more to this StarVision camera by MallinCam than just an amazing new sensor!\u003c\/p\u003e\n\u003cp\u003eThe MallinCam StarVision Video CCD camera is in a class of its own. At the heart of the StarVision camera are internal 64 MB memory modules. This feature is not found on competitive cameras. By having dual internal memory modules, the data transmission load on the internal electronics is dramatically reduced. Also by incorporating DSP (digital signal processing) and other MallinCam developed noise reduction technologies, the StarVision achieves a level of low noise not achieved by other ICX825 CCD cameras.\u003c\/p\u003e\n\u003cp\u003eCameras from other manufacturers utilizing the ICX825 CCD sensor produce single frame images suffering from noise. To achieve acceptable images, stacking of multiple frames is needed. The StarVision is capable of producing excellent smooth, live, noise-free images without the need for subsequent stacking in a computer!\u003c\/p\u003e\n\u003cp\u003eCircuit board technology employed in the StarVision camera from MallinCam: The front circuit board containing the CCD sensor is free of any other electronic components. This eliminates electronically induced noise from affecting the sensor and dramatically reduces heat from reaching that sensor. This technology is not utilized by other camera manufacturers. In addition, industrial grade components have been used throughout the camera's three double-sided populated circuit boards. Finally, the front CCD sensor board is made with 24 karat gold plating to insure the ultimate in connection integrity and low noise performance. Careful planning went into the design of this ultra-compact USB camera, making it usable with either ALT-AZ or Equatorial mounts.\u003c\/p\u003e\n\u003cp\u003eThe StarVision from MallinCam is designed and built for a lifetime of durability. The body is manufactured from CNC-machined aluminum and stainless steel, and the machine screws are also of stainless steel for outdoor durability. The rigidity of the case insures that the sensor will maintain permanent alignment and the sealed, clear, multicoated optical window insures that the CCD sensor will never need cleaning. This design provides the low maintenance factor you want in a camera. The professional USB 2.0 locking terminal and cable are designed for use in all environments and are especially suited for use outdoors. This is an astronomy camera!\u003c\/p\u003e\n\u003cp\u003eThe software is supplied on a USB stick and can be installed on your favorite PC.

Usually, a single filter is attached to an eyepiece, then the combination of eyepiece and filter is inserted into a telescope focuser to achieve a filtered view. To change the filter, you would normally have to remove the eyepiece from the telescope, unthread and exchange the filter, then re-insert the eyepiece and adjust focus. This process can be a hassle, especially if you wish to use more than one 2\" filter during a single stargazing session to compare filtration effects.

Set...\u003c\/h2\u003e\n\u003c\/center\u003e\n\u003cp\u003eEven before the disappearance of the famed Baader Genuine Orthoscopics, Baader Planetarium sought to develop a true Planetary eyepiece set that was accessible for any amateur - without breaking their bank. Introducing the \u003cb\u003eBaader Planetarium Classic Eyepieces and Q-Turret Eyepiece\u003c\/b\u003e sets.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eForegoing fancy (and costly) cosmetics, the Classic Eyepieces deliver where it counts - performance. Their sharpness and contrast rival other ''planetary'' eyepieces costing much more. To achieve this performance and value, Baader drew upon their extensive in-house knowledge and experience, combined with optical designs and processes leveraged from Zeiss.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe Classic Q-Barlow has been optically matched to the \u003cb\u003eBaader Classic Q-Turret Eyepieces\u003c\/b\u003e, and its 2.25X magnification gives a well spaced set of focal lengths. It''s removable lens cell can also be unthreaded from the 1.25\" barrel, and directly threaded onto any of the eyepieces to give 1.3X, further filling in the choice of focal lengths. Alternatively, it can be directly threaded onto the 1.25\" barrel of the Q-Turret to give 2.25X with all 4 eyepieces.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe perfect complement to the \u003cb\u003eBaader Classic Q-Turret Eyepieces\u003c\/b\u003e. Baader''s new 4 position Q-Turret enables rapid magnification change with a twist of the turret.

No longer do amateurs need to spend more on their eyepieces than their primary instrument in order to get true high-end performance in a wide-field eyepiece. Not just a different branded version of their highly regarded cousins, the Hyperions have been totally redesigned to deliver better transmission, contrast, and useful new features.

The Hyperion multi-coatings and coating equipment are proprietary to Baader and have been designed by German coating engineers specifically for the Baader Hyperions, and optimized for each of the glasses used. These coatings are applied with the latest thin-film German coating equipment, training, and process controls. The result are coatings that truly rival the best in the world - including the famous Zeiss Abbe Orthoscopic!

Based on the popular Baader Moon \u0026amp; Skyglow filter, the Baader Contrast-Booster takes contrast enhancement and skyglow reduction to the maximum level possible from a filter. Not only does this filter deliver a significant enhancement to planetary and lunar contrasts, but it is designed to also totally eliminate the damaging blue de-focused haze present in achromatic refractors. Gone are the annoying blue halo and obscuring haze that surround and smear resolution and contrast. Subtle contrasts and colors are boosted, while displaying the full resolution your scope is capable of.\u003c\/p\u003e\n\u003cp\u003eAvailable in both 1.25\" and 2\" Round Mounted styles, the \u003cb\u003eBaader Contrast Booster Filter\u003c\/b\u003e combines a special proprietary melt of Neodymium glass with a carefully designed 23 layer dielectric long-pass blocker on one face, and a 7-layer ultra-low anti-reflection coating on the other face. By aggressively filtering out the defocused blue wavelengths, a light yellow tint is imparted to objects (noticeably less than a typical yellow filter). The special coatings enable over 95% transmission across key portions of the visible spectrum (including H-Alpha). This results in a filter that retains the colors and color contrasts in tough subjects like Jupiter, without excessive image dimming. Cloud bands retain their ruddy red hues, but now become more striking in contrast. The Great Red Spot finally becomes easier. Planets and Lunar landscapes are set against a jet black sky. The Contrast-Booster is a must for Solar observing when used in conjunction with Baader Astro Solar.\u003c\/p\u003e\n\u003cp\u003eAs many users have found, the \u003cb\u003eBaader Contrast Booster Filter\u003c\/b\u003e is a great filter for Mars! The views of Mars with all telescopes (including reflectors and apochromats) benefit from the RGB filtration plus blue blocking. Combined with the Baader UV-IR-Cut Filter, the Contrast-Booster makes the ideal filter set for digital imaging. Rather than add the cost of additional IR filtration (only needed for digital imaging), the Baader Contrast Booster has been optimized for visual use. Digital imagers can simply add our Baader UV-IR-Cut Filter when needed. The true 1\/4 wave fine optically polished surfaces guarantee the sharpness and contrast of the image.

It has been recognized by astronomy enthusiasts around the world and has become a must-have for anyone using an equatorial mount for visual use or for imaging. The PoleMaster electronic polar axis alignment device is a patented product of QHYCCD and is protected by Chinese, US patents and International PCT.\u003c\/p\u003e\n\u003cp\u003eAs any seasoned astroimager would agree, achieving good polar alignment is not an easy task. You may spend hours under precious dark sky trying to get that perfect polar alignment, but in the end you may not know whether good alignment has in fact been achieved. Even after you have obtained good alignment, a gentle knock on the mount may send the polar alignment off and you may have no other choice but to start from scratch again. With an hour here and an hour there trying to get polar aligned, it soon will be dawn and time to pack up the gear.\u003c\/p\u003e\n\u003cp\u003eThe PoleMaster is a great solution to this problem. The PoleMaster is an innovative product pioneered by QHYCCD to relieve the pain of polar alignment. Using PoleMaster and following a few simple, easy-to-follow, steps you can achieve perfect polar alignment in 2-3 minutes, with an accuracy of up to 30 arc seconds.\u003c\/p\u003e\n\u003cp\u003eWith Polemaster, You don’t need to rotate the telescope to some uncomfortable position to keep the optical polar axis of the equatorial mount unobstructed. Also, you don’t need to squat down to look through the polar axis scope. You don’t need to turn off all the light sources to allow the naked eye to adapt to the darkness and look for the Polaris in the field of view. You also don’t need to enter the date and time and then rotate the equatorial mount to a strange angle, finally you don’t need to adjust the equatorial level. With the PoleMaster you can observe the alignment of the polar axis at any time, as well as continuously monitor the polar axis. When the equatorial mount moves inadvertently, you can also tune it back without having to redo everything.\u003c\/p\u003e\n\u003cp\u003eThe PoleMaster’s pixel resolution is approximately 30 arc seconds. The camera’s pixel matrix itself is a good ruler, so the accuracy it measures is much higher than the accuracy of the macroscopic lens. In the best case it can achieve an alignment accuracy of 30 arc seconds. The electronic polar mirror also has a large field of view of 11 degrees x 8 degrees, so it is easy to find the Polaris.\u003c\/p\u003e\n\u003cp\u003eOnce you have calibrated with a PoleMaster, you only need to perform a single-star sync (one-star calibration). This greatly facilitates the setup of an equatorial mount.\u003c\/p\u003e\n\u003cp\u003eWith a suitable adapter ring (sold separately), the PoleMaster can be mounted to any equatorial mount. Even single-axis equatorial mounts that have no ability to correct in declination will benefit because with the PoleMaster, after the polar axis is aligned, the amount of drift in the declination direction will be very small, which can further improve the performance of such an equatorial mount.\u003c\/p\u003e\n\u003cp\u003eHow does PoleMaster work? Well, the idea is actually fairly simple. You find out where the pole is, then determine the mechanical axis of rotation of your mount and finally make the two coincide. While the idea is simple, this has not been implemented in a commercial product - until now. PoleMaster makes use of a super sensitive wide field imaging camera along the axis of RA to monitor the polar region in real time (so not only it can detect Polaris but also the dimmer stars surrounding). From the positions of these stars PoleMaster can determine the position of the true pole and compare that to the mechanical axis of RA rotation. Polar alignment is now a simple matter of moving the two centres of rotation so they overlap. Piece of cake!\u003c\/p\u003e\n\u003ch4\u003eIn comparison with other polar alignment techniques, PoleMaster has the following advantages:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSpeed and convenience: With PoleMaster you do not need to move the telescope to a specific place just to unblock the polar scope. You do not need to kneel or contort your body to look through the polar scope. You do not need to fully dark adapt just to see the pole star. You do not need to level your mount. You do not need to worry about the entering the date and time in your handset and figure out where to rotate the mount to coincide with the current pole star position.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eAccuracy: With a high precision camera, one can achieve accuracy not achievable with the naked eye.

Other filter suppliers try to \"force fit\" their orange filter (designed for the interline KAI11000, KAI2000 sensors) for use with these full-frame sensors. Their orange filter is about twice as wide spectrally as Astrodon's deep red filter. As a result, their orange filter tends to \"wash out\" HII regions in galaxies and detail in nebula. Their blue and green color weights are no longer balanced and as a result, the OIII color in planetary nebula is skewed strongly toward blue, rather than the correct teal color.

The narrow 5 and 3 nm bandwidths enhance contrast of emission targets by lowering your background signal. The guaranteed \u0026gt;90% transmittance at the emission wavelength provides you with the highest signal available. This guaranty is expensive to manufacture for such spectrally narrow filters, but it assures you in writing on each filter box that you will get what you paid for. These two factors combine to provide you with the highest contrast available. Our latest narrowband filters are typically achieving \u0026gt;95-98% transmittance. Astrodon Narrowband filters are renowned for minimizing halos around bright stars, even for long exposures of 30-45 minutes typical of narrowband imaging in astrophotography. Lastly, Astrodon Narrowband filters are coated to the edge of the part and are edge blackened. This is critical to minimize stray light for a filter that blocks most light except for the narrow bandpass.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"astrodon","offers":[{"title":"Default Title","offer_id":43447475175537,"sku":"USED061203","price":1249.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/20260612_101717.jpg?v=1781273953"},{"product_id":"baader-solar-continuum-filter-2-pre-owned","title":"Baader Solar Continuum Filter 10nm  - 2\" (Pre-owned)","description":"\u003cp\u003e\u003cspan style=\"color: rgb(245, 15, 15);\"\u003e\u003cstrong\u003eIn excellent condition!\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(245, 15, 15);\"\u003e\u003cstrong\u003e\u003cspan\u003ePlease note The Solar Continuum filter must be used with a primary white-light broadband solar filter (ie, Herschel Wedge Prism, or Baader AstroSolar Film).  It must be placed \u003c\/span\u003e\u003cspan\u003eafter\u003c\/span\u003e\u003cspan\u003e the primary filter, and cannot be used alone!\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe new Baader Solar Continuum filter is designed to enhance the visibility of solar granulation and sunspot details.
