The Astro Physics Tele Compressor was originally designed for telescopes with a focal ratio of f/9 or higher, but practical use has shown that it also works exceptionally well with GSO’s RC telescopes. It delivers sharp star images across a 29 mm diameter field. When used with an SLR camera, the required spacing can be achieved using a TS Optics 2"/T2 focal adapter, providing the standard 55 mm distance to the camera sensor needed for DSLRs with a T2 ring.

Astronomik Filters CLS CCD XT Clip Sony alpha 7 (85677)
5414.74 Kč

Astronomik XT filters enable you to capture sharp, beautiful star images right into the corners of the frame, even with extremely wide-angle lenses. With other Astronomik filters, image quality in the corners can be limited at short focal lengths. Although these filters use a glass plate only one millimetre thick, this thickness can cause aberrations with certain wide-angle lenses, stretching stars into lines. Astronomik XT filters are built on an ultra-thin substrate, just 0.3 millimetres thick. This thinness minimizes “star streaks” in the corners.

These are safe, full aperture solar filters, sometimes called clear aperture filters. They are designed to allow the maximum amount of light into the telescope by making use of the full aperture. This provides the best possible daytime viewing, especially when atmospheric turbulence is minimal. If turbulence is present, a mask can be placed over the end of the filter to effectively reduce the aperture. This premium solar filter features an aluminum cell that is secured and centered on the end of the telescope tube with nylon thumb screws and felt padding.
