The Altair 2" Solar Continuum filter Enhances sunspots, granulation, and fine photosphere detail. For use with Baader Solar Filter or Herschel Wedge. IMPORTANT SAFETY INFORMATION: DO NOT USE THIS FILTER FOR DIRECT SOLAR OBSERVATION! Must be used together with a professional solar filter or Hershel Wedge with Max. 0.024% transmission placed BEFORE this filter. For reflecting telescopes, we recommend Baader solarfilm on the front of the telescope, then screw the filter into a filter holder, camera, or eyepiece. For refractors, the filter should be positioned just in front of the camera or eyepiece with a Hershel Wedge in place. Do not use this filter without a suitable solar pre-filter in place, because it will permanently damage your eyes or camera! The Solar Contrast Booster works by filtering out UV, IR and visual wavelengths except for a narrow 8nm FHWM green band at 540nm. This greatly increases the contrast of solar features when viewed with the naked eye, colour or mono camera, revealing more detail around sunspots and granulation (fast-developing solar convection cells) in the solar photosphere. Highly recommended for use with either Altair Imaging-Ready APM Hershel Wedge or Baader Solar Film. NOTE: Do not insert the filter before your Hershel Prism or it will melt, it should be placed just in front of the camera, and it should be screwed directly into your camera 2" nosepiece by means of the M48x0.75mm thread, E.g. Hypercam 2" nosepiece or use an Altair Magnetic Filter holder with 2" filter slider (Search product code starting with "MAGF" and choose the correct threads for your camera). Why is transmission centred on 540nm wavelength? 540nm is a very desirable wavelength for imaging and observing the sun. The Solar Contrast Booster filter improves performance of any telescope optics such as Refractors, Newtonian reflectors, Maksutovs, Dall Kirkhams, Cassegrains, and SCT's. It's especially recommended with Frauenhofer Achromatic refractors and short focal length ED Doublets, because their optimum performance peaks in this green wavelength by design. In fact, not only Achromats, but most ED triplet and APO refractors traditionally have peak performance at 540nm wavelength, where the human eye shows best sensitivity. 530-540nm is not only the traditional "design benchmark wavelength" for most telescope optics, and also that of most high end interferometry equipment used to configure and optimise telescope lenses. Most colour and mono CMOS cameras also have peak sensitivity and resolution in green! Colour CMOS cameras in particular have an RGGB pixel layout with two green pixels for every one blue and red pixel, for an obvious increase in resolution. The are therefore many benefits in isolating this wavelength to capture those fleeting moments of good seeing.

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height 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. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

Altair Premium Positive-Lock Diagonal - Dielectric 2 inch Pushfit The Altair 2" premium diagonal with positive-lock system grips 2" accessories tightly with a small rotation of the top knurled ring, keeping them precisely centred. The CNC machined chassis will hold extra heavy accessories without flexing, and the mirror features a premium 99% reflective dielectric-coating. Ideal for refractors and large eyepieces or binoviewers, the positive-lock has a very light action and only needs a small 20 degree rotation, letting you quickly replace accessories. There's no need to apply excessive force on thumbscrews or normal twist-lock mechanisms to insert accessories. Once you've tried it, you won't want to use any other diagonal again, it's that easy.

TS Optics Non rotating helical focuser with M48 connection A true helical focuser like this works like a camera objective - when you turn the focusing ring, neither the lens nor the camera (or eyepiece and diagonal) will rotate. The only motion is in and out. The advantage of this helical focuser is the fine adjustment, possible in part due to the fine pitch of the focusing ring's thread, and in part due to the large diameter of the ring. In the case of this helical focuser, virtually backlash-free movement and graduated markings on the focusers allow repeatable return to the focus point simply by noting the focus position reading. Advantages at a glance no rotation of the diagonal or camera - the only motion is in and out precisely adjustable limitedly self-locking wide focus range: 40 mm 51 mm minimum height, 91 mm maximum height easy adaption to the telescope tube and the camera good solution for telescope or objective self construction M48x0.75 (2" filter) threads at both sides, with all adaption possibilities generous clear aperture of 45 mm also suitable as variable M48 extension 51 mm to 91 mm for the perfect working distance two screws for locking the drawtube Wide focussing range and short length The Helical focuser has a wide focussing range of 40 mm, but it is very short, with a minimum height of only 51 mm. So you can use the focuser on telescopes or telephoto lenses with little space to the focus point, like Newtonians. Accessories This focuser is not suitable for heavy accessories, it will tilt. The main use is with small CCD cameras for planetary photography, 1.25" eyepieces and lightweight 2" eyepieces. Delivery contents Helical Focuser with 2 locking screws

Baader Glasspathcorrector for binoviewers The corrector is more than just a simple barlow lens that compensates for part of the optical path of the binoviewer. First of all, the corrector corrects the color fringes created by the prisms of the binoviewer. Contrast and sharpness of the image increase. Calculation of the shortening factor: The corrector is installed directly in front of the binoviewer. If the corrector is moved further away from the binoviewer, the magnification effect and path compensation increase. ♦ GWK 1,25x: The optical path of the binoviewer is shortened by 18 mm. ♦ GWK 1,7x: The optical path of the binoviewer is shortened by 41 mm. ♦ GWK 2,6x: The optical path of the binoviewer is shortened by 84 mm. Adaptation to the telescope: Adaptation to the binoviewer is simple. The corrector is simply clamped between the T2 female thread and the T2 male thread. The adapter is automatically centered. For the connection to 1.25" or 2" we recommend suitable Baader adapters which are linked under the accessory recommendations. Further application possibilities: The correctors are not only suitable for the Baader Maxbright binoviewers. Also for other binoviewers or adapters, prisms ... the correctors can be used. Whenever you cannot reach the point of focus with a new accessory, the Baader Glass Path Corrector can be the saving solution.

Manufacturer's product description: Motor drive suitable for the following telescopes : Omegon 150/750 EQ-3 Teleskop Omegon 76/900 EQ-2 Teleskop Zoomion Gravity 150 EQ Omegon EQ-3 motor drive - the motor drive for your Omegon EQ-3 telescope It is clear starry night. An object is in the field of view - perhaps the planet Jupiter - you note how the planet slowly moves in the field of view. You continually have to use the manual slow motion controls of your telescope to get the object back into the centre of the field of view. But this is also possible automatically Use the simple method of employing a tracking motor with your Omegon EQ3 mount. This will save you having to constantly adjust the telescope by hand. Once attached, you will then be able to concentrate much better on your observing. The motor relieves you of this irksome burden and will track your telescope in synchronisation with the movement of the stars from now on. The object you are observing will remain permanently in the field of view when the motor is operating! Even more features You also receive a handbox for controlling your telescope with the Omegon EQ-3 motor drive. Four large keys provide 8x and 2x tracking speeds and for temporarily stopping tracking. This means you can also follow objects at higher speeds and keep them positioned in the field of view. There is also an ON/OFF switch and a switch for selecting which hemisphere you are on. This means that the Omegon RA tracking motor can be used anywhere in the whole world. The handbox is ergonomically designed so that it is easy and safe to use even when wearing gloves. The advantages in a nutshell: RA axis motor for automatic tracking drives the main axis of the telescope well suited to visual observing comfortable to use: manual adjustment is no longer necessary straightforward assembly, only taking a few minutes handbox for 2X and 8X tracking speeds switch for northern and southern hemispheres It's a clear starry night. The object is located in the field of view, the planet Jupiter perhaps. You watch how the planet rapidly moves out of the field of view. The manual slow motion controls of your telescope allow you get the object back into the field of view... This is also possible automatically Take the easy way and use the tracking motor for your Omegon mount. It saves you constantly having to adjust the position of the telescope by hand. Simply connect it up and you can concentrate on observing. The motor now does all the work, and from now on will move your telescope at exactly sidereal speed. The object remains permanently in the field of view, as long as the motor is running! Yet more features Along with the Skywatcher motor, you will also get a hand box for controlling your telescope. Four large buttons are used for 8X and 2X sidereal speeds, and there is also a pause button. This enables you to move an object into position in the field of view at a higher speed. In addition to the ON/OFF switch, there is a switch for selecting which hemisphere you are located in. This means the Omegon RA tracking motor will work anywhere in the world. The hand box is easy to hold and operate, so you are always in control even with gloves on. The advantages in a nutshell: RA axis motor for automatic tracking powers the main axis of the telescope suitable for visual observing easy operation - manual tracking no longer necessary easy installation which takes only a few minutes hand box for 2X and 8X speeds switch for Northern and Southern hemispheres battery compartment, with cable, for six D batteries
