This applies to most telescopes.\u003c\/p\u003e\n\u003cp\u003eWhile Barlow lenses serve to shorten the optical path to accommodate the binoviewers, other factors such as your the amount of inwards travel of your focuser, the light path length of you diagonal and the telescope design will also influence whether or not the binoviewers will come to focus on your system. SCT's or Schmidt Cassegrains may not always require a Barlow lens, because the mirror shift focusing range is quite large.\u003c\/p\u003e\n\u003cp\u003eSince binoviewers are predominantly used for solar system observing, the use of Barlow lenses is an advantage, because it allows you to maintain the more generous eye-relief of longer focal length eyepieces, making the placement of your eyes less critical relative to the rear lenses. This enables binoviewer owners to still achive medium to higher powers quite comfortably.\u003c\/p\u003e\n\u003cp\u003eSome Altair refractors have a \"binoviewer friendly\" design with a removable extension, which serves to shorten the distance between focuser and front lens, making bino-viewing without a Barlow possible too.\u003c\/p\u003e\n\u003cp\u003eRecommended eyepieces for binoviewing include the Altair Ultraflat 24mm and 18mm (Product code: AAUF18 \/ AAUF24) which have a stainless steel barrel without the usual cone-shaped undercut, and which perform extremely well with the Altair Premium Binoviewer.

Firstly, examine the image of the target object in the video preview window. You should see a subtle \"rainbow effect\" on objects below an altitude of 40 degrees above the horizon. This effect is increased the closer you get to the horizon until it's very obvious. To see the \"rainbow effect\" more clearly it is recommended to  increase the saturation control of your camera (this feature is found under the \"Colour Adjustment\" menu in AltairCapture and other image capture software and it will not affect the final image provided you are imaging in RAW mode recording .SER files which is the best setting for solar system imaging). Because adjustment of the prisms offsets the image slightly, it helps to zoom in (mouse wheel in AltairCapture) to see it more clearly while starting at lower powers then moving to higher powers - look along the border of high contrast features on the moon and the edge of planets to see the effect more clearly. \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eStep2:\u003c\/strong\u003e\u003cspan\u003e Learn to orientate the unit with the horizon line. \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eStep 3:\u003c\/strong\u003e\u003cspan\u003e Learn to adjust. Move the levers together or apart, to change the divergence angle of the prisms relative to each other. By changing the angle of deviation, you will get a feel for the optimum position by viewing the target object in preview mode. Once you are satisfied with the image, and the \"rainbow\" effect is cancelled out, your prisms are set. The prism levers overlap so that most of the time you won't need to rotate the ADC itself, however you may need to rotate it a little to accommodate the overlap, which is as large as it can be without causing the body of the ADC to flex too much. Be patient. It takes a little time to get the feel of an ADC, possibly a session or two, however the results are well worth it and they are far higher quality than attempting to align the colour channels in post processing software because you are starting with a better image. We recommend putting the barlow lens in front of the ADC in most situations as the prisms will perform better at highre focal ratios used in solar system imaging. \u003c\/span\u003e\u003c\/p\u003e","brand":"Altair Astro","offers":[{"title":"Default Title","offer_id":44895313625408,"sku":"ADC","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/9904\/6464\/products\/altair-adc-atmospheric-dispersion-corrector-19-p.jpg?v=1682268788"},{"product_id":"altair-finder-clamp-for-mg60-guidescope","title":"Altair Finder Clamp for MG60 Guidescope","description":"\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eSecurely mount your MG60 Guidescope with the Altair Finder Clamp.

Both solar photography or visual observation:\u003c\/strong\u003e\u003cspan\u003e Often solar wedges don't give enough light for high speed exposures needed to \"freeze\" air-motion for a sharp image. The Altair Solar Wedge has an AR coated internal polarising filter, which let's you control the brightness of the image. Brightness can be increased or decreased by rotating the top assembly, then locking it in the desired position with a side thumbscrew. Variable brightness is very important both for visual and imaging use, to fine tune the ideal exposure time, or the ideal contrast levels at the eyepiece - especially when adding a colour filter such as a green continuum filter for extra contrast. Unlike other makes, the Altair Solar Wedge enables both visual and imaging applications \u003c\/span\u003e\u003cstrong\u003ewithout having to change internal filters.\u003c\/strong\u003e\u003cspan\u003e With the solar wedge in \"bright\" mode, exposure times as low as 2 milliseconds are routinely possible with high speed CMOS cameras like the Altair Hypercam or GPCAM.

Each wedge ships with instructions which must be read and understood completely before using the product. Never allow children to observe the sun with a telescope and wedge or filter without the supervision of a knowledgeable adult. Never remove a solar filter or wedge without first placing the front lens cap on the telescope. Always securely fasten solar filters or Solar Wedge securely to the telescope. Always remove any optical finder from the telescope before pointing it at the sun because you could inadvertently look through it. (Use the safe Altair solar finder with Solar Filters or Wedge.

Remember this product cannot be used with a reflector, refractors only!\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ: How do I \"tune\" the image brightness for imaging?\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eA: When imaging the sun using \"lucky\" imaging techniques with a high frame rate camera like the Altair Hypercam, it's best to keep the exposure duration of the camera as short as possible - ideally under 10 milliseconds is ideal, though less than 5ms is even better. This \"freezes\" air motion to show granulation and other small details. Being designed for visual or imaging use, the internal polariser module (controlled by rotating the turret top) has a wider brightness range than normal Hershel wedges allowing fast frame rates and short exposure duration. When set for fast frame rates, the image can appear very bright visually through an eyepiece - like looking at a light bulb. This is uncomfortable, but not dangerous due to the protective ND filter inside the unit allowing 0.1% of light through. Therefore, an additional 1.25\" neutral density filter is provided, which transmits 75% of light, blocking 25% for initial focusing and setup with an eyepiece. When you first set up the Wedge and align it with the sun for visual use, you should add the provided 1.25\" Neutral Density filter to the eyepiece, then rotate the turret-top until the image is quite dim. Once you are satisfied with the balance of contrast and sharpness, lock the polariser locking thumbscrew, and you are ready to observe. If using the wedge for imaging only, you can just insert the camera and turn the turret-top until you are satisfied with the exposure duration and gain settings. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ: For how long can you keep the wedge aimed at the sun?\u003c\/strong\u003e  A: The Altair Solar Wedge has been fully tested with the sun remaining in the centre of the field of view for 5 hours of continual exposure with a 6\" (152mm) aperture refractor in mid-summer in the UK. At no point did the outer prism housing become too hot to touch, a problem common with other wedges. Whilst we cannot recommend use with telescopes of larger than 6 (152mm) aperture for longer or shorter duration, if your telescope is larger, then we suggest trying the wedge for a short time initially, to assess the heat build-up and make your own informed decision.\u003c\/p\u003e","brand":"Altair Astro","offers":[{"title":"Default Title","offer_id":44895315525952,"sku":"SOLWEDGE2","price":379.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/9904\/6464\/products\/altair-imaging-ready-2-inch-solar-herschel-wedge-v2-445-1-p.jpg?v=1682268824"},{"product_id":"altair-starwave-universal-finder-mounting-shoe","title":"Altair Starwave Universal Finder Mounting Shoe","description":"\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003eDiscover limitless stargazing with the Altair Starwave Universal Finder Mounting Shoe.

For visual use it can be used to tune-in and hold the \"sweet spot\" to get the best preformance from your Quark or any Solar telescope with an Ha Etalon filter.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eFor deepsky imaging the tilt adjuster is used to compensate for inevitable tilt changes in the \"imaging train\" when accessories like a filter wheel, focuser, and so-on are used. This gives a more even pattern of star shapes in the image. Especially important when using field flatteners or coma correctors to fine tune the image.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe M48 Tilt adjuster is precision machined in our workshop on a CNC lathe with M48x0.75 male and female threads on each side. (Also known as \"astro-filter\" thread). It therefore can be used with most extension tubes and adapters. 3 tilt adjustment screws are arranged in a 120 degree opposing pattern. They can be locked in position after adjustment using the corresponding locking screws.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eWith the camera tilt adjuster, adjustment to fractions of a millimeter are possible for a perfectly flat field with optimal off-axis image sharpness. No more hunting the \"sweet spot\" for your particular setup, just leave it on! The camera tilt adjuster is ideal for use with larger CCD chips or DSLRs as well as field flatteners and reducers in any fast optical system, where deviation from the focal plane edge is more critical.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe M48 tilt adjuster adds 10-11mm to the light path, depending on the amount of tilt adjustment. Being M48 format on both sides, the camera tilt adjuster is fully compatible with the Altair range of M48 spacers and adapters, and it can be connected directly with most Altair flatteners and DSLR adapters using the wider M48 format. Of course you can convert it to M42 on the camera side by using the M48 female to M42 male step-down adapter.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ: When is the camera tilt adjuster required?\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ea) For deepsky imaging with fast focal ratio telescopes:\u003c\/strong\u003e\u003cspan\u003e Any train of imaging adapters, flatteners and filters is inevitably slightly tilted from the ideal focal plane due to the combined effect of several accessories all connected together, multiplying the almost invisible tolerances in connections between parts. The combined effect can often be seen at the edges of your CCD or DSLR camera chip. DSLRs often suffer from very slight misalignment too which adds to the effect. Some CCD cameras have built-in tilt adjusters to compensate for this, however most cannot be adjusted once the camera is connected and focused. The camera tilt adjuster is recommended for use with all cameras and flatteners where stars appear slightly different, i.e. elongated or larger and fuzzier one or more of the field edges. It fits between the focuser and telescope. It can be adjusted in real-time for best results, using the easily accessible push-pull collimation screw system at the sides. For the perfectionist, it's possible to use CCD Inspector software to derive the exact amount of tilt as a numerical value, and to adjust it out of your imaging train completely. The tilt adjuster can also be used to centre reflections on the camera cover glass (halos caused by filters look better on-centre) and to manage alignment issues between filter wheel, off-axis-guiders, and other parts of your imaging system. Example setup: Camera \u0026gt; M48 Adapter \u0026gt; M48 Tilt Adjuster \u0026gt; Field Flattener \u0026gt; Focuser\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eb) For solar imaging with a hydrogen alpha Etalon filter to cure alignment problems:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eFirstly Etalons often create artifacts known as \"Newton's Rings\" and \"Banding\" in solar images taken with mono and colour cameras. By tilting the camera relative to the Etalon filter these effects can be reduced or eliminated. Example setup: Camera \u0026gt; 1.25\" to 2\" Adapter \u0026gt; M48 Tilt Adjuster \u0026gt; Quark \u0026gt; Extension Tube \u0026gt; Focuser.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eSecondly, focuser sag or mis-alignment of the focuser to optical axis can cause problems: Often the full disc solar image can give uneven illumination and certain off-band areas, causing areas on the solar surface or prominences to appear less contrasty - or sometimes even dissappearing completely. You can use the tilt adjuster before the quark to adjust for the best image to reduce these issues. Example setup: Quark \u0026gt; Extension Tube \u0026gt; M48 Tilt Adjuster \u0026gt; 2\" Barrel \u0026gt; Focuser\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWhat types of optical systems are likely to benefit from the camera angle tilt adjuster?\u003c\/strong\u003e\u003cspan\u003e Most optical systems will show tilt if it's present, and tilt is more often than not there - if you consider the number of threaded accessories being used!
