A suitable T-2-ring for your camera must be ordered separately.\u003c\/p\u003e\n\u003cp\u003eThe OPFA projection systems can be set to be light-tight and bolt-tight, so nothing can wobble anymore. With additional T-2 extension tubes, even extreme projection scales can be achieved – even with CCD cameras!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEach eyepiece projection\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eworks in the same way, although there are some practical differences wheather the camera is used WITH or WITHOUT lens. When working with a (digital) SLR camera, the lens is usually removed, and the camera body is attached directly to the projection unit.\u003c\/p\u003e\n\u003cp\u003eIf the camera lens is integrated into the system, this is called afocal projection. This is the usual method when shooting with digital viewfinder cameras, where the lens can NOT be removed. For these cameras, we recommend the ADPS, which can be set to a short distance between eyepiece and camera lens. The following diagram shows the structure of the classic eyepiece projection with cameras, where the lens can be removed.\u003c\/p\u003e\n\u003cdiv class=\"leftImage\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/1_d3de799b-720e-499f-8ec9-bd7bb8303025.webp?v=1733589603\" alt=\"\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/1_d3de799b-720e-499f-8ec9-bd7bb8303025.webp?v=1733589603\u0026amp;width=700\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"leftImage\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe focus plane or focal image of the telescope is projected onto the film\/camera sensor via a projection eyepiece (similar to a slide projector, which projects the magnified slide onto a screen). The resulting focal length is called the equivalent focal length (f\u003csub\u003eE\u003c\/sub\u003e).\u003c\/p\u003e\n\u003cp\u003eThe reproduction scale depends on the focal length of the eyepiece (f\u003csub\u003eEP\u003c\/sub\u003e) and the projection distance (a). The equivalent focal length is calculated as follows (the longer it gets, the bigger the image on the film becomes):\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ef_\u003csub\u003eE\u003c\/sub\u003e\u003cspan\u003e \u003c\/span\u003e= f\u003csub\u003eprimary\u003c\/sub\u003e\u003cspan\u003e \u003c\/span\u003e× ((a ÷ f\u003csub\u003eEP\u003c\/sub\u003e) - 1)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe effect of the different parameters can easily be seen from the formula. If the eyepiece focal length is reduced and \/ or the distance a (between focal point of the eyepiece and the camera sensor\/film) is increased, the value of the equivalent focal length (and with it, the magnification) increases; the picture gets bigger.\u003c\/p\u003e\n\u003ch4\u003eOur OPFA units are set up (from right to left) as in the following example\u003c\/h4\u003e\n\u003cp\u003eThe parts marked in\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003eblue\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003ecorrespond to the OPFA-4 basic version, which has a male T-2-thread on the with camera side and a female T-2-thread on the telescope side.

Shown in the picture are OPFA-1 (1¼\" nosepiece) and OPFA-2 (2\" nosepiece). If your focuser has a different connector, you have to choose between OPFA-3 and OPFA-7 (e.g. OPFA-3 for Celestron and Meade Schmidt-Cassegrain telescopes).\u003c\/p\u003e\n\u003cp\u003eThis is followed by a sliding focuser with a T-2 locking ring. The 1¼\" eyepiece (not supplied) is inserted into this sliding focuser and clamped in. The function of the locking ring and the sliding focuser is described below.\u003c\/p\u003e\n\u003cp\u003eNow, the two 40mm T-2 extension tubes are screwed onto the sliding focuser, the eyepiece (\u003cstrong\u003eouter diameters of up to 38mm are possible\u003c\/strong\u003e) will be inside of the T-2 extensions. The extensions are used to set the distance between eyepiece and camera (ie to establish the projection distance). By adding more T-2 extensions (see our Astro T2 system), the distance (and the image) can be enlarged.\u003c\/p\u003e\n\u003cp\u003eThe OPFA is connected to the (digital) SLR camera through a camera-specific T-ring (not included).\u003c\/p\u003e\n\u003ch4\u003eThe function of the sliding focuser and the locking ring\u003c\/h4\u003e\n\u003cp\u003eThe sliding focuser makes a fine adjustment of the projection distance possible a by slightly pushing the eyepiece forward or backward.\u003c\/p\u003e\n\u003cp\u003eBy loosening the locking ring, the complete unit can be rotated steplessly, until the attached camera is to set to a favorable orientation. Of course, for the models OPFA-1 and OPFA-2 the camera can also be rotated with the complete unit.\u003c\/p\u003e\n\u003cp\u003eIn the models OPFA-3 to OPFA-7, the connection from the OPFA to the focuser is a rigid screw connection. Here, the camera orientation can only be changed via the locking ring of the sliding focuser.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv aria-hidden=\"false\" role=\"tabpanel\" aria-labelledby=\"st-link-opfa-system-layout_0-1\" id=\"st-opfa-system-layout_0-1\" class=\"station-tabs-content is-active\"\u003e\n\u003cdiv class=\"station-tabs-content-inner\"\u003e\n\u003cp\u003eThe below system layout gives an idea of the flexibility and different configurations possible for use in a standard eyepiece projection setup (see below images for some afocal setups). The OPFA takes advantage of its compatibility with the Astro-T2 System, permitting you to design the exact system to fit your needs. Any 1.25\" eyepiece (up to 37mm body diameter) may be used. The eyepiece is securely retained with a separate knurled lock screw.\u003c\/p\u003e\n\u003cp\u003eThe OPFA incorporates a novel sliding focuser assembly (#24), which permits you easily vary the distance between the eyepiece and camera (total travel of 12mm). Simply loosen the lock screw, adjust the focus tube, and securely lock in place at the desired position. Additional distances can be achieved by the use of any of our Extension Tubes (two 40mm extension tubes #25B are supplied as part of the OPFA). This feature is particularly valuable in matching the eyepiece-to-lens distance for afocal projection systems (see below for some images of several digital cameras setup for afocal projection imaging).\u003c\/p\u003e\n\u003cimg height=\"303\" width=\"554\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/OPFA_ANZ_en.gif?v=1733589747\" alt=\"\"
