While the idea is simple, it has never 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 (it not only detects Polaris but also the dimmer stars surrounding Polaris).  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 centers of rotation so they overlap.

The Celestron Off-Axis Guider uses a prism to intercept a small portion of the telescope’s focal plane (outside the field of view of the main imaging camera) to locate a guide star. Any movement seen by the guide star will be the exact same movement seen by the imaging camera. Guiding this way will correct for tracking errors, as well as opto-mechanical errors or flexure. The result: better astroimages with pinpoint round stars.\u003c\/p\u003e\n\u003cp\u003eOff-Axis Guiders have been around for a long time, but typically pose three main challenges:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eFinding a guide star from the far edges of the telescope’s focal plane can be difficult, considering the small field of view and sometimes less-than-ideal illumination.\u003c\/li\u003e\n\u003cli\u003eGetting both imaging camera and autoguider to reach focus with one another is time consuming and sometimes requires experimentation.\u003c\/li\u003e\n\u003cli\u003eAdditional spacers and adapters are usually required for your particular camera, telescope, and autoguider, which adds to cost and complexity.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eCelestron's Off-Axis Guider addresses these challenges by:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eProviding a large 12.5 mm prism that can be adjusted to move closer to the center of the telescope’s focal plane, depending on the size of the imaging camera.

This ensures that if you rotate the Origin camera to better frame your target, or when new cameras become available in the future, you can easily capture a new flat-frame image. The Celestron app will then use this updated image to enhance calibration, delivering the best possible results. Retaining the advanced features of GIOTTO, this version has been uniquely designed for seamless integration with Celestron Origin, providing a perfect fit as a replacement for the standard telescope cap. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe Celestron Origin Smart Telescope is designed to simplify deep-sky imaging, automatically applying factory-calibrated flat frames to enhance image quality. However, when the camera is rotated to better frame a target or when new cameras become available in the future, the original calibration becomes inaccurate, requiring a new flat frame capture. This is where the GIOTTO for Origin flat field generator comes in. Designed specifically for the Origin telescope, GIOTTO ensures precise and consistent flat frame calibration by uniformly illuminating the optics with our advanced LED technology. It seamlessly fits onto Origin’s dew shield, locking securely in place, and allows users to wirelessly control brightness levels via their smart device. With GIOTTO for Origin, astrophotographers can easily recalibrate their telescope whenever needed, ensuring the highest image quality for every capture.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"GIOTTO for Origin Smart Flat Field Generator\" src=\"https:\/\/www.primalucelab.com\/img\/cms\/GIOTTO-for-Origin-smart-flat-field-generator-description1-EN.jpg?1742377424133\" title=\"GIOTTO for Origin Smart Flat Field Generator\" width=\"1000\" height=\"596\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eGIOTTO for Origin Smart Flat Field Generator - \u003cspan\u003emain features\u003c\/span\u003e:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eDesigned for Celestron Origin Intelligent Home Observatory\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eLED lights at color temperature similar to sunlight, to provide a \u003cstrong\u003eneutral color tone\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSpecial designed \u003cstrong\u003elight diffuser\u003c\/strong\u003e for an even illumination\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eAdjustable light intensity\u003c\/strong\u003e by 100 steps (0 to 100%)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eIt operates on a 12V power source\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eUSB-C port\u003c\/strong\u003e to let you easily connect it to a Windows computer\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eWiFi connectivity\u003c\/strong\u003e so you can wirelessly control it using your smartphone or tablet via the included Virtual HandPad\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eControl with \u003cstrong\u003ePLAY astrophotography software\u003c\/strong\u003e for Windows computers\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eASCOM driver\u003c\/strong\u003e to let you control it through third party softwares\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWeight: 0.4 kg (0.9 lb)\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"853\" height=\"480\" src=\"https:\/\/www.youtube.com\/embed\/FROZ1PiHEkg?rel=0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eUse the \u003cspan\u003eVirtual HandPad\u003c\/span\u003e to control GIOTTO using the same smart device used to control Origin\u003c\/h2\u003e\n\u003cp\u003eControlling GIOTTO for Origin is as intuitive as using your Origin Smart Telescope.

But when you point a camera at it, f\/7 starts to show its hand. Exposures take longer than you'd like. The field curves toward the edges. Stars that looked pinpoint at the eyepiece start bloating into little comets in the corners of your image. None of that is the scope's fault — it's just what an uncorrected optical path does to a flat sensor.\u003c\/p\u003e\n\u003cp\u003eThe AT80EDRF fixes both problems at once. It reduces the focal length from 560mm to 448mm, bringing the scope down to f\/5.6 — a 56% increase in light-gathering speed per pixel. And it flattens the field across the sensor, pulling those corner stars back into tight, round points. The result is a faster, wider, flat-field imaging system for under $90, designed specifically for this scope.\u003c\/p\u003e\n\u003ch3\u003eDedicated — Not Generic\u003c\/h3\u003e\n\u003cp\u003eThis reducer was designed to match the AT80ED's native focal length and field curvature. It isn't a universal 0.8× reducer that sort-of-works on multiple scopes — it's purpose-built for the AT80ED (2018 model year and newer). The optical correction is tuned to this specific scope, which means the stars it delivers are round across the field when the back focus is set correctly. Generic reducers can get you close. Dedicated reducers get you there.\u003c\/p\u003e\n\u003ch3\u003eSensor Coverage\u003c\/h3\u003e\n\u003cp\u003eThe AT80EDRF is designed for APS-C sensors and smaller. On an APS-C chip, the corrected field is clean edge to edge — no vignetting, round stars all the way to the corners. Dedicated CMOS astronomy cameras with sensors up to about 16mm diagonal (like the ZWO ASI533MC or ASI294MC) fit comfortably inside the corrected circle. On a full-frame sensor, you will see vignetting in the outer third of the frame. This is not a full-frame reducer — the copy is honest about that, and you should factor it into your camera choice.\u003c\/p\u003e\n\u003ch3\u003eSimple Connection\u003c\/h3\u003e\n\u003cp\u003eThe telescope side is a standard 2\" barrel that slides directly into the AT80ED's focuser. The barrel includes 2\" filter threads, so you can thread in a light pollution or narrowband filter inline — no separate filter drawer needed. The camera side terminates in M42×0.75 T-threads, connecting to a T-ring for DSLR and mirrorless bodies, or directly to dedicated CMOS and CCD astronomy cameras, which come with 42mm T-threads built in.\u003c\/p\u003e\n\u003cp\u003eBack focus is 55mm from the reducer's shoulder to the imaging plane. For most DSLR setups with a standard T-ring, that spacing is close to correct out of the box.

If your stars look fine in the center but stretch toward the edges, you probably don't have an optical problem — you have a spacing problem. Measure the distance from the reducer's shoulder to your sensor and aim for 55mm. A set of M42 spacer rings (available in 1mm, 2mm, and 5mm) lets you dial it in without guesswork. Get the spacing right once, mark your configuration, and you won't have to think about it again.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this work with the AT80EDT (triplet)?\u003c\/strong\u003e\u003cbr\u003eNo. The AT80EDRF is designed specifically for the AT80ED doublet (2018 and newer). The AT80EDT is a different optical design with a different focal length and field curvature. The AT80EDT has its own dedicated reducer and field flattener options — check those product pages for the correct match.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this work with a full-frame camera?\u003c\/strong\u003e\u003cbr\u003eIt will physically connect, but the corrected image circle does not cover a full-frame sensor. You'll see noticeable vignetting in the outer third of the frame. For full-frame imaging, you'd need a reducer designed for a larger image circle. This reducer is optimized for APS-C and smaller sensors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat cameras work best with this reducer?\u003c\/strong\u003e\u003cbr\u003eAPS-C DSLRs (Canon Rebel\/EOS, Nikon DX), Micro Four Thirds bodies, and dedicated CMOS astronomy cameras with sensors up to about 16mm diagonal. The ZWO ASI533MC, ASI294MC, and similar cameras are confirmed to work well by Cloudy Nights users.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a T-ring?\u003c\/strong\u003e\u003cbr\u003eIf you're using a DSLR or mirrorless camera, yes — you need a T-ring for your specific camera mount (sold separately). Dedicated CMOS and CCD astronomy cameras typically have M42 T-threads built in and connect directly without a T-ring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use a filter with this reducer?\u003c\/strong\u003e\u003cbr\u003eYes. The 2\" barrel has internal filter threads. You can thread in a 2\" light pollution filter, UHC, or narrowband filter before inserting the reducer into the focuser. One CN user noted that placing filters in a drawer (rather than front-threading) can help fine-tune back focus if you run into spacing issues.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow critical is back focus?\u003c\/strong\u003e\u003cbr\u003eVery. The reducer is optimized for 55mm from its shoulder to the sensor. If your spacing is off by more than a millimeter or two, you'll see elongated stars toward the edges. M42 spacer rings let you adjust in small increments. Get it right once and it stays right.\u003c\/p\u003e\n\u003ch3\u003eFinal Thoughts\u003c\/h3\u003e\n\u003cp\u003eIf you're imaging with an AT80ED and you don't have a reducer yet, this is the one that was designed for your scope. It's not trying to be a universal solution — it's a precision match for this specific optical system, and that specificity is exactly why it delivers flat fields and round stars where generic reducers fall short. At $90, it turns a good visual scope into a capable widefield imaging system. Pair it with an APS-C DSLR or a small-sensor astro camera, get the back focus dialed in, and start shooting.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"manuals\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"shopify-section-template--16234575298633__recommendations\" class=\"shopify-section product-recommendations--section\"\u003e\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Astro-Tech","offers":[{"title":"Default Title","offer_id":47966355849475,"sku":"U2603-BM-AT80EDRF","price":60.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1979\/5379\/files\/23fae937-ce39-43b5-93b1-2e47ca03fadd.jpg?v=1776799174"},{"product_id":"used-dgm-npb-nebula-filter-2","title":"Used DGM NPB Nebula Filter - 2\"","description":"\u003cp\u003eThis is an DGM NPB Nebula filter in very good condition.  The optics are clean.  Comes in its original plastic case.  Snap this up before someone else does!  \u003cmeta charset=\"utf-8\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eAny dust you see in the photos is easily removable - it seems that these filters develop an electrostatic charge such that the dust in the air is just attracted to the filter.  \u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cem\u003e\u003cstrong\u003e\u003cspan\u003e\u003cu\u003eThe NPB\u003c\/u\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/em\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003e\u003cspan size=\"3\" style=\"font-size: medium;\"\u003eThe NPB is the ONE filter to have if you have just one, and now regarded as the top narrowband  (UHC type) filter in the world.

However, the series can also be thought of as an extension of the long eye relief Nagler Type 4 concept. With the all-new Type 7 design layout, we achieved our goal of Apollo 11-like performance across a series of focal lengths that are eyeglass friendly.\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"fs_italic\"\u003e\u003cb\u003eDesign Goals:\u003c\/b\u003e\u003c\/span\u003e The design goal was simple. The performance of each of the Type 7 focal lengths must equal or exceed that of the Apollo 11 eyepiece in the areas of full-field sharpness, contrast, distortion correction, eye relief, and pupil comfort, but across an 82° apparent field of view instead of 85°.\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"fs_italic\"\u003e\u003cb\u003eDesign Details:\u003c\/b\u003e\u003c\/span\u003e If you have been waiting for a Nagler series for eyeglass wearers, the Type 7 is it. Combining the expansive 82° apparent field of view with 19 mm of eyeglass friendly eye relief, and large eyelens, the Nagler Type 7s give a new dimension to the \"spacewalk\" viewing effect. An easily adjustable, locking eye-guard is included for those who don't wear eyeglasses. It helps to correctly position your eye to the exit pupil so you don't get too close to the eyelens, as well as blocks contrast-robbing stray light from interfering with the view. Speaking of which, of course we've applied all the optical coating and baffling features Tele Vue eyepieces are known to maximize contrast and complement the fully corrected field; revealing beautifully natural star colors with pinpoint sharpness. The optical layout affords unrivalled parfocality throughout the four focal lengths and even between 1¼\" and 2\" modes when used with the Tele Vue Hi-Hat 1¼\" and 2\" adapter (ASF-8125). The Type 7 series is also parfocal with all other 1¼\" Tele Vue eyepieces (except 40 mm Plössl) when those eyepieces are used in the Tele Vue Hi-Hat 1¼\" and 2\" adapter (ASF-8125).

Tele Vue Plössls, designed by Al Nagler, have been a recognized benchmark of performance and value in the class of 50° apparent field of view eyepieces. While the Plössls may be TeleVue's least expensive eyepiece line, they still enjoy the same care and attention to detail as their most expensive. While it's easy for other manufacturers to vie for the lowest price, Tele Vue continues to believe that quality, performance and consistency will ultimately reward you with the most value for your dollar.\u003c\/p\u003e\n\u003cp\u003eDiffraction limited \"on-axis\" performance is a given. Using more expensive high-index glasses to reduce astigmatism and lateral color at the field's edge, Tele Vue Plössls deliver sharper images than any other brand of 4 or 5 element \"Plössls\" or Orthoscopic designs. The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue eyepieces. Tele Vue Plössls feature full multicoatings for greatest light transmission and contrast. Blackened lens edges and internal anti-reflection threads tweak the last bit of contrast for maximum image detail.

It provides the highest contrast in the photosphere of the sun. The filter works as a monochromator: suppressing the effects of the atmospheric turbulence and delivering images that are significantly sharper.\u003c\/p\u003e\n\u003cp\u003eLens systems - including those of apochromats, catadiopters or eyepieces - are traditionally optimized for the spectral range around 540nm, since this is where our eye has the highest sensitivity. This narrowband filter therefore blocks everthing with the exception of the spectral range in which a lens optic works most sharply and with the highest contrast. The effect is greatest on achromatic lens telescopes; but there is also an effect on apochromatic telescopes, catadioptric systems, and even pure mirror systems by reducing air turbulence.\u003c\/p\u003e\n\u003cp\u003eAs a monochromatic filter, it is ideal for use on monochromatic cameras and can even provide a tremendous gain on pure color systems.\u003c\/p\u003e\n\u003cp\u003eWith a colour camera, as with deep-sky narrow-band photography, it is less effective as only the green pixels are used. Thus, although you still benefit from the improved image sharpness of the telescope that is optimised for green wavelengths (and the reduction of the influences of air turbulence), with a colour camera you cannot fully exploit the better image quality compared to monochrome cameras, as you are effectively working with reduced camera resolution.\u003c\/p\u003e\n\u003cp\u003eCompared to the previous model with a 10nm half-band-width, this filter has a half-band-width of only 7.5nm, which increases the contrast even more. It thus replaces both the previous Baader 10nm Solar Continuum filter and the stacked 1 ¼\" filter #2458392. The single filter is so good that stacking is no longer necessary - the contrast gain of a single 7.5nm filter makes stacking unnecessary, and this performance is now also available in 2\".\u003c\/p\u003e\n\u003cp\u003eThe Baader 7.5 nm Solar Continuum also offers all the advantages of the CMOS-optimized Baader filters:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncreased contrast, matched for typical CMOS quantum efficiency and s\/n ratio\u003c\/li\u003e\n\u003cli\u003eReflex-Blocker™ coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics\u003c\/li\u003e\n\u003cli\u003eIdentical filter thickness to existing standards, with utmost care for parfocality\u003c\/li\u003e\n\u003cli\u003eBlackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter\u003c\/li\u003e\n\u003cli\u003eEach filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed)\u003c\/li\u003e\n\u003cli\u003eLife-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eManufacturer: Baader Planetarium\u003c\/li\u003e\n\u003cli\u003eNet Weight (kg): 0.067\u003c\/li\u003e\n\u003cli\u003eTransmission Range: 535 – 545 nm\u003c\/li\u003e\n\u003cli\u003eFilter Thickness (Without cell): 2 mm\u003c\/li\u003e\n\u003cli\u003eHBW (Halfbandwith): 7.5 nm\u003c\/li\u003e\n\u003cli\u003eCWL (Central Wavelength): 540 nm\u003c\/li\u003e\n\u003cli\u003eAR-Coating: Reflex-Blocker™ hard coated, planeoptically polished\u003c\/li\u003e\n\u003cli\u003eFilter Size: 2 inch\u003c\/li\u003e\n\u003cli\u003eFilter Usage: CMOS, Contrast Enhancement, Solar\u003c\/li\u003e\n\u003cli\u003eFilter Mounted: Mounted (LPFC 6mm)\u003c\/li\u003e\n\u003cli\u003eType of Filter: Narrowband\u003c\/li\u003e\n\u003cli\u003eSingle or Set: Single Filter\u003c\/li\u003e\n\u003cli\u003eFilter Shape: round\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eManufacturer part number: 2961581 or FSOL-2N\u003c\/p\u003e","brand":"Baader","offers":[{"title":"Default Title","offer_id":48431932768515,"sku":"U2606-MK-Baad-Solar","price":60.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1979\/5379\/files\/original-736.jpg?v=1781729539"}],"url":"https:\/\/milehighastro.com\/collections\/used-eq-mounts.oembed?page=6","provider":"Mile High Astronomy","version":"1.0","type":"link"}
