The tele-extender (a 4" to 6" tube with internal threads that fit the externally-threaded 1.25" visual back of your scope at one end and external threads for a T-ring on the other) is threaded onto the visual back, over the eyepiece. Values obtained in this section may be used in the above sections. Field of View is an angle which depends on the focal length and sensor size, but it also computes dimensional Field of View sizes (width, height, or diagonal fields) at some specific distance, like at the subject distance, or at a background distance.

Add to cart. Steve says: "Eyepiece projection is a method of capturing images through a telescope's eyepiece using a camera with its lens removed, and is normally used where high magnification is required, for example when imaging planets or features on the Moon. After connecting the eyepieces, the distance between the front and rear can be adjusted to zoom in or out to obtain a zoomable image. Astronomics is a family-owned business that has been supplying amateur astronomers, schools, businesses, and government agencies with the right optical equipment and the right advice since 1979. Next, determine the diameter of the eye piece. The major drawback to eyepiece projection, unless you use a specialty eyepiece, is field curvature (where only the center of the field is crisp while focus drops off rapidly away from the center). This calculator will give you the necessary exposure time with a given CCD and telescope needed... Knowing the field of view of a CCD camera on a certain telescope is critical when selecting targets for imaging. The document has been permanently moved to here. The eyepiece projection calculator can be downloaded from here, along with the VB runtime files if required. The formulas employed by these calculators are approximations.

Some are examples from my telescope, a C11 SCT with 279.4 mm of aperture and 2,794 mm focal length at f/10. Calculate the FoV Factor for SIM Racing. The adapter works with standard 1.25" eyepieces with body diameters up to 37 mm. On the first T-2 thread you can connect normal T-rings, so you have a 2x Barlow lens - with 1 1/4 " barrel - in front of every camera, webcam or DSLR camera housing. I wanted to have the possibility of imaging using eyepiece projection so I thought I'd try to put something together with what I already have and 3D print the rest. To calculate the projection distance, the distance fom the eyepiece to the projection plane, simple optics can be applied: Projection Distance = (Magnification + 1) * EyepieceFocalLength. An enlargement of the imaging scale up to three times is possible without loss of quality. This practical manual provides essential material for the extensive world-wide community of non-professional astronomers. The Baader Hyperion 8-24mm Zoom Mk IV Eyepiece is the pinnacle in quality and optics for zoom eyepieces. We don't care about your term 'magnification' when describing a projector lens. An standard visual eyepiece is designed to give parallel rays. Eyepiece Projection Calculator -- computes the optimum separation between the eyepiece and camera and computes the final image scale for any given separation. Your camera is connected to the lens by means of an optional T-ring. The formulas employed by these calculators are approximations. It can be used with all Astro T-2 system components. the Deluxe Tele-Extender calculator will show that your new effective focal length will be 22,600 mm, with a magnification of . Field of View is an angle which depends on the focal length and sensor size, but it also computes dimensional Field of View sizes (width, height, or diagonal fields) at some specific distance, like at the subject distance, or at a background distance.
