Easier for beginners, certainty for professionals! The completely redesigned and revolutionary collimator version 3.0 for your telescope. The market continues to develop towards short focal lengths and highly sensitive cameras with extremely small pixel sizes. This increases the requirements for a clean telescope alignment. The Ocal collimator is an innovative tool, which facilitates the adjustment in a completely new way. Each Ocal collimator has an internal motor that moves the CMOS chip linearly. Via the software, the focus can thus be ideally adjusted to the individual areas of the alignment. So you can focus on any area in the telescope without touching the setup or imagetrain. Colored centering circles can be selected and adjusted via the included software. The software also controls the line width of the circles as well as the contrast and exposure of the live image. Last but not least, a fade cross can be switched on and rotated via software. In this way, all areas that are important for the adjustment can be brought into focus and concentrically aligned very precisely. With the alignment of the crosshairs, the exact linear alignment of the trap can be assessed. Scope of delivery: OCAL 3.0 Connection cable 2x adapter Closing cap

The Skywatcher 0.85x focal reducer / field flattener has been designed for astronomers who want to use the renown ED Apo for astro photography. The flattener reduces the telescope's focal length by the factor of 0.85 and increases the useful field. As a positive side effect, the necessary integration times are significantly reduced. The field curvature that is unavoidable at most telescope systems is reduced to a nearly irrelevant level when using sensors up to APS-C format (24x16mm). Optimal distance M48 - focal plane: 55mm

Masuyama eyepieces are known for their clear and high contrast imaging and velvet black background. The good contrast of these high-end eyepieces is achieved with a special cut, internal diaphragms and the best possible internal blackening. Due to the elaborate lens design, the eyepieces get by with only 5 elements, with good correction at the same time. Despite the large field of view, the short focal length Masuyama eyepieces are highly recommended for planetary and double star observation. At the same time, the eyepieces are of course very nice overview eyepieces for deep-sky observation. The long focal length eyepieces are well suited for finding and observing large area deep sky objects. The eyepieces were developed by renowned optician Dr. Masuyama. Among other things, Dr. Masuyama designed an eyepiece with a focal length of 100 mm, which was used on the historic 60-inch telescope at Mount Wilson Observatory in California. We are pleased to offer you these legendary eyepieces with the latest glass and coating technology. Scope of Delivery: Eyepiece Dust caps

Altair QuadBand is the new trend in light pollution filters for deep-sky imaging of emission nebulae with colour CMOS, CCD, and DSLR cameras. Altair V2 Filter Technology produces even better blocking of unwanted wavelengths, higher transmission, and no halos. The result is a better signal to noise ratio for imaging emission nebulae with a DSLR or CMOS Astro camera. The 35nm passband not only makes the QuadBand V2 compatible with fast focal ratio lenses and telescopes, but also allows visual use with a relatively small telescope in urban locations. Brighter emission nebulae can be observed in urban conditions with a darker background. This is the new QuadBand V2 Coating technology which includes: Anti-Halo coating on both surfaces to reduce reflection artefacts from reducers and camera lenses. Increased blocking of UV, IR and unwanted visual range wavelengths. UV OD7 (T0.00001%) Visual OD5 (T0.001%) and IR OD4 (T0.01%) for the ultimate in skyglow blocking. An order of magnitude better than foreign filters. Higher transmission % of desired wavelengths Ttop 95% (Average 5% higher transmission of desired wavelengths). Ha and Oiii wavelengths at 35nm FWHM for with less tail-off to reduce unwanted light pollution. It's even compatible with fast scopes, like Altair F6 refractors which operate at F4.8 with reducers, and the F2 Celestron RASA and Hyperstar. Includes UVIR blocking for both modified and un-modified DSLR cameras, plus an anti-reflection coating to reduce halos as much as possible. Narrowband Bi-Colour imaging is a growing new trend in astrophotography, especially popular in light polluted areas, or for imaging in rural areas in moonlight. Now you can capture the two main emission nebulae bands at the same time, whilst suppressing light pollution, moonlight, and airglow. Capture more data in less time, and open up your imaging time window - even into the summer months. Altair QuadBand light pollution filters work by isolating the primary nebulae emission zones in the red and blue/green wavelengths, and separating them into two main "zones" with a wide separation for easy capture with a colour camera - all in one exposure! Not only is capture very convenient, but processing is easy too, thanks to the wide separation of the green/blue and red "zones". Light pollution control is extremely effective and LED light is also significantly reduced, thanks to the effects of Rayleigh scattering. Sensitive OSC or "One Shot Colour" CMOS cameras like the #Hypercam183C capture these wavelengths very efficiently, and allow them through the Bayer matrix. The filters also work with DSLRs (APS-C sensor size modified cameras are best, but normal ones will also work). When you have the complete stack of exposures, processing is relatively easy because of the large separation in colour. You can also use the Quad band and Tri-Band filters as a "super luminance filter" for imaging nebulae with Mono cameras. A quick overview of the Altair Filter family: QuadBand Filter - combines Sii AND Ha into a red zone, and H-beta + Oiii into a green/blue zone. (Recommended for moderate light pollution and skyglow, used with colour cameras). TriBand Filter - combines Ha into a red zone, and H-beta + Oiii into a green/blue zone. (Recommended for higher light pollution, used with colour cameras). DualBand Filter - separates the red Ha and blue Oiii channels even more distinctly with even deeper blocking. (Recommended for severe light pollution such as within built-up areas such as cities. Used with colour cameras). NarrowBand mono camera filter - these isolate single bands, so you only capture one wavelength per filter such as Oiii or Ha or Sii, and they are mostly used with mono B&W astronomy cameras. Separate sets of exposures are required with each filter. Filter Specifications: 1st band, CWL495nm FWHM35nm 2nd band, CWL 660nm FWHM 35nm 1.85mm thick optical glass with 30 arc sec parallelism. UVIR Block and Anti-Reflection Coating. Scope of Delivery: Filter 2"

The Altair 395nm NUV filter selectively passes light of the two main Calcium wavelengths emitted by the sun: CA-K line at 393.37nm, and the CA-H line at 396.85nm. A specially developed multilayer interference coating results in transmission of approximately 75% at 395nm NUV wavelength. Bandwidth is approximately 7nm (FHWM), resulting in extremely high contrast in the selected wavelength with efficient blocking of unwanted wavelengths. Remaining UV and IR light between 400-1100nm is blocked at OD3 0.1%, and visible light between 400-700nm at OD4 0.01%. Imaging the sun: The filter is to be placed in front of a high speed CMOS video camera for displaying detail in the upper solar atmosphere, at the boundary between the photosphere and the chromosphere. Structures which cannot normally be seen by the human eye or cameras are revealed, including fast-evolving Ellerman bombs (micro-flares) and Plages, (bright networks near sunspots). Solar granulation is also enhanced, as well as umbral detail around sunspots. Imaging the planet Venus: The planet Venus also benefits greatly from higher contrast in the upper cloud layers, showing features normally invisible in white light. The high transmission allows fast frame rates. IMPORTANT: The 395nm wavelength is harmful and almost invisible to the eye, therefore the NUV filter is intended for photographic use ONLY. A pre-filter of at least OD3.8 is required to reduce radiation damage to the filter. A Herschel Wedge, such as the Altair Imaging-Ready Solar Wedge can be used, or solar film, provided the manufacturers instructions are followed correctly. Refractors are usually employed for solar imaging, however reflectors can be used, provided they have a large blocking filter over the front aperture (usually solar film or glass filter because Hershel Wedges cannot be used with reflector telescopes). Imaging requires a monochrome CMOS camera. A typical example with false colour and selective contrast processing is shown opposite (HDR filter, Photoshop). Specification: NUV transmission band, CWL 395nm FWHM 7nm Filter substrate: 1.85mm thick BK7 optically polished glass with 30 arc sec parallelism UVIR blocking: UV and IR light between 400-1100nm is blocked at OD3 (0.1%) Visible light blocking: Visible light between 400-700nm at OD4 (0.01%) Scope of Delivery: Filter Specifications: Cell: Aluminium Type: Interference filter Filter thread / size: 1.25"

Product description TS Optics Off Axis Guider with Zeiss M68x1 connection - short design Off axis guider for large cameras This big off axis guider with Zeiss M68 thread connection is a consequent further development of the short TSOAG9. This model is designed for heavy cameras with large sensors. With an optical length of 16.7 mm, it also needs not much back focus. But nevertheless, it offers all options needed for professional tracking. Advantages and characteristics M68x1 Zeiss thread on both sides Length 16.7 mm only (w/o male threads) Choice of three positions (120° each) for the sidewards T2 guiding cam adapter, thus you have always a good framing option for the sensor Free aperture of 62.5 mm: even large camera sensors can be used without vignetting Massive design: all connections are screwed, no clamping. This is ideal for heavy cameras. The guiding focus can be adjusted individually The prism can be shifted in order to reach an optimal position relative to the main sensor Internal surface with anti-reflective thread Three connections for the prism tower Due to the massive design, this OAG has no rotation functionality that could compromise the solid connection of heavy cameras. Three positions (3 x 120°) can be used for the guiding tower. Inappropriate prism positions relative to the main sensor (e.g. in front of an edge) are prevented. If the guiding cam collides in one position with the main camera, another position can be chosen. The two holes not in use can be closed to prevent stray light from entering the system. Short design The off axis guider is consequently designed for short design without compromising its stability or ease of use. All elements can also be operated when wearing gloves. Distances to prism Distance from female M68 thread to prism center: 11.5 mm Minimum distance from prism center to T2 thread: 27 mm Delivery contents Off axis guider
