With a 40 mm aperture and 180 mm focal length, it operates at a fast f\/4.5: complete constellations, the Milky Way, and large nebulae fields fit comfortably in the frame, with short exposure times and low noise.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Integrated corrector, direct flat image<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The built-in corrector keeps stars round in the corners, without a separate flattener. You can directly connect system and DSLR cameras via the T2 connection, and the included tube rings and dew shield make the tube ready for use on a star tracker or light mount. This is also a surprisingly versatile instrument as a super telephoto lens for wildlife photography.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>In the box<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Optical tube FMA180 40\/180 with integrated corrector<\/li>\n\n\n\n<li>T2 camera mount<\/li>\n\n\n\n<li>Tube Rings<\/li>\n\n\n\n<li>Dew cap<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">For whom yes, for whom no<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">For astrophotographers who want to capture maximum sky fields with a minimal setup. Not for those looking for the latest version; the FMA180 Pro has a larger corrected image circle of 44mm for full-frame and is also more affordably priced.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Specifications<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Optical design<\/td><td>Apochromat with integrated corrector<\/td><\/tr><tr><td>Opening<\/td><td>40 mm<\/td><\/tr><tr><td>Focal length<\/td><td>180 mm<\/td><\/tr><tr><td>Opening ratio<\/td><td>f\/4,5<\/td><\/tr><tr><td>Camera connection<\/td><td>T2<\/td><\/tr><tr><td>Attachment<\/td><td>Tube Rings<\/td><\/tr><tr><td>Execution<\/td><td>OTA (loose tube)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Unsure about the right tube for your camera and mount?
