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

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
