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 controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring’s power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers’ heater output ports, or to a third-party controller’s heater output port.

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.

advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 62° Series Argon-Purged Waterproof wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The 62° Series eyepieces are near par-focal (meaning they focus at nearly the same point regardless of the focal length you select) and come with a removable and foldable soft silicone rubber eyecup for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope.\u003c\/p\u003e\n\u003cp\u003eProtection from the Outdoors - By making the eyepiece body Argon-purged, the waterproof eyepiece internal elements will remain as pristine as the day they were assembled.  \u003c\/p\u003e\n\u003cp\u003eArgon atoms are larger than that of Nitrogen and therefore they are less likely to leak or diffuse their way through the seals over the life of the eyepiece. The atomic radius of Argon is larger than Nitrogen by 0.13 angstroms and has a larger atomic volume by 11.2 cubic centimeters\/molecule. Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components, and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And, finally because Argon is less conductive of heat than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics.\u003c\/p\u003e\n\u003cp\u003eThe sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Our waterproof eyepiece is easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements. To insure a perfect seal we test every eyepiece in one meter of water for 30 minutes.\u003c\/p\u003e\n\u003cp\u003eExplore Scientific Waterproof Eyepieces - Comfort, Quality, Value. The Explore Scientific 62° Series eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 62 degrees and near par focal design, these eyepieces offer incredible value in a very nice eyepiece. \u003c\/p\u003e\n\u003cp\u003eAnother great benefit of these eyepieces is the excellent contrast and ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cdiv class=\"rte__table-wrapper\"\u003e\n\u003ctable height=\"375\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.272251%;\" bgcolor=\"#dad4d4\" width=\"28%\"\u003eDescription\u003c\/td\u003e\n\u003ctd style=\"width: 70.680628%;\" bgcolor=\"#dad4d4\" width=\"70%\"\u003e 62° Series Argon-Purged Waterproof Eyepiece\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.272251%;\" bgcolor=\"#eeeeef\"\u003eItem Number\u003c\/td\u003e\n\u003ctd style=\"width: 70.680628%;\" bgcolor=\"#eeeeef\"\u003eVaries\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.272251%;\" bgcolor=\"#dad4d4\"\u003eFocal Length\u003c\/td\u003e\n\u003ctd style=\"width: 70.680628%;\" bgcolor=\"#dad4d4\"\u003eVaries\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.272251%;\" bgcolor=\"#eeeeef\"\u003eLength\u003c\/td\u003e\n\u003ctd style=\"width: 70.680628%;\" bgcolor=\"#eeeeef\"\u003e\u003cspan\u003e76mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.272251%;\" bgcolor=\"#dad4d4\"\u003eWidth\u003c\/td\u003e\n\u003ctd style=\"width: 70.680628%;\" bgcolor=\"#dad4d4\"\u003e\u003cspan\u003e50mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.272251%;\" bgcolor=\"#eeeeef\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"width: 70.680628%;\" bgcolor=\"#eeeeef\"\u003e\u003cspan\u003e8.2oz; 323.47g\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.272251%;\" bgcolor=\"#dad4d4\"\u003eBarrel Size\u003c\/td\u003e\n\u003ctd style=\"width: 70.680628%;\" bgcolor=\"#dad4d4\"\u003e1.25\" and 2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.272251%;\" bgcolor=\"#eeeeef\"\u003eEye Relief\u003c\/td\u003e\n\u003ctd style=\"width: 70.680628%;\" bgcolor=\"#eeeeef\"\u003e\u003cspan\u003e19.3mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.272251%;\" bgcolor=\"#dad4d4\"\u003eField Stop Diameter:\u003c\/td\u003e\n\u003ctd style=\"width: 70.680628%;\" bgcolor=\"#dad4d4\"\u003e27.3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Explore Scientific","offers":[{"title":"5.5mm","offer_id":47882177282307,"sku":"U2603-JH-EPWP6255LE-01","price":30.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1979\/5379\/files\/original-310.jpg?v=1774652166"},{"product_id":"used-orion-highlight-plossl-eyepieces","title":"Used Orion Highlight Plossl Eyepieces","description":"\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThese are used Orion highlight plossl 1.25\" eyepieces in excellent condition.

That means that every air-to-glass lens surface is multi-layer coated for the highest possible light transmission and better contrast. You'll see more of those pinpoint star images and more faint detail in deep-sky objects. In addition, the lens edges are blackened for additional contrast enhancement.

HighLight barrels have a setscrew safety recess to reduce the risk of an eyepiece falling out should the locking setscrew become loose. And of course they are internally threaded to accept filters.

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. Dedicated astro cameras may need a spacer or two to dial it in precisely — and it's worth getting right, because back focus is where the difference between round stars and stretched stars lives.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e0.8× dedicated optical reduction.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDrops the AT80ED from 560mm f\/7 to 448mm f\/5.6 — 56% more light per pixel and a wider field of view.

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.
