DMK41AU02.AS Mono USB Camera; Resolution of 1280 x 960 pixels With a resolution of 1280 x 960 pixels, the astro CCD camera DMK 41AU02.AS is particularly suitable for detailed images. Despite this high resolution, this telescope camera offers recordings with up to 15 frames/s. With the included software IC Capture.AS you can save them lossless and uncompressed into an AVI file. Monochrome Sony CCD The basis for the high-resolution images of the telescope camera DMK 41AU02.AS is the CCD ICX205AL from the manufacturer Sony. With a format of 1/2" it offers a resolution of 1280 x 960 pixels. Its noise is low even at long exposure times. Its noise is low even at long exposure times. Due to its high quality, the CCD is also frequently used in industrial image processing. No compression, no filters The DMK 41AU02.AS CCD camera outputs its image data without compression. IR cut filters, color filters or even the various forms of electronic filters are not used. As a result, it guarantees unaltered images of the night sky. Fast transfer thanks to USB 2.0 Both the high-resolution, uncompressed images of the DMK 41AU02.AS telescope camera and its high frame rate generate an enormous amount of data. To be able to transfer them, a very fast interface is required - USB 2.0. Software for Windows included This camera is delivered with the driver IC WDM DCAM TIS and the operating software IC Capture.AS.

ASI T2-Tilter - Tilt flange Adjustment of image plane and sensor position Many astrophotographers know the problem: You focus as good as possible and in 1-2 corners the sharpness is still not satisfying. The result is a bad compromise, by changing the sharpness setting until the stars appear relatively evenly "sharp" or by simply cutting away the corner. Some possible causes of this problem: ♦ a slight tilt of the camera sensor (only a few fractions of a millimeter are enough) ♦ a tilt of the focuser ♦ a slight tilt of the field plane of the telescope (very common with Newtonian telescopes) ♦ a tilting of the eyepiece-side accessories during clamping This is the solution: With the ASI T2 tilter you simply adjust the chip of the camera to the field of the telescope, no matter where the cause of the tilt comes from. You only have to keep the orientation of the whole adapters, correctors and camera. Connecting the camera to the tilter: In principle, any suitable camera can be connected to the tilter via the T2 thread. However, additional bores also allow the connection directly to the camera body on the following ZWO cameras: ♦ ASI294/ASI1600/ASI183/ASI533 Pro cooled ♦ ASI294/ASI1600/ASI183/ASI174 uncooled With the ASI071 and ASI 2600 Pro the housing is differently dimensioned, the direct connection does not work. There it only works via the T2 thread.

APM MS 20 x 110 ED Binocular

Item condition: new and original packed

Product description Anyone who seriously wants to observe at a high level needs a powerful optics. Our APM MS 100mm binoculars already have 3x as much light collecting area than 50mm binoculars. This results in a significantly increased resolution, limiting magnitude (astronomy) and magnification in the terrestrial area. New fields open up for the nature observer, as distant objects remain recognizable even in difficult light situations. The amateur astronomer will appreciate the increased object brightness, which makes detailed observation much easier. The price-performance ratio is excellent! The large 4 "ED optics are modern, multi-coated, as also the BAK-4 prism system is. This enables sharp, high-contrast and bright object imaging, even in difficult light conditions. Our model 34x100 offers an AP of 4mm, an optimal value for long-term detailed observations. But a tripod is recommended for observation (adapter included). The APM Magnesium binoculars uses high quality ED glass (FK61) as well as BAK-4 prisms for maximum contrast and highest sharpness over the entire field of view. Special coatings on all optical surfaces eliminate disturbing reflections and ensure natural colors. With a interpupillar distance of 16mm, the eyepiece construction is good suitable for people who wear glasses. The rubber eyecups can be folded down. The entire system got the IPX-7 certification for protection against the ingress of water. Our binoculars is completely protected against rain and immersion in water, so it is completely weatherproof. The magnesium body is very lightweight and yet very robust. A rubber armouring is attached to the housing, which further protects the glass and gives you a secure grip and hold. Delivery: Binoculars ED 34x100 Tripod adapter Carrying case Lens hoods
