Back Focus Calculator at Ryan Bruce blog

Back Focus Calculator. The back focus for your telescope imaging train is the measured distance from the last optical component at the back of the telescope, whether it’s a coma corrector or field. In this article, we’ll go over why back focus spacing is so important to get right, everything to consider for back focus spacing, and how to use adapters and spacers to get. Common missteps in achieving correct back focus. Learn how to measure back focus when using a corrector or reducer, and how to adjust it for different cameras and sensors. The fundamental role of back focus in astrophotography. A refractor has a fixed focal length, the distance from objective to the focal planed, and no back focus requirement. Learn how to calculate the spacing between your camera and corrective optics for astrophotography. To be able to calculate the back focus distance whilst maintaining the optimal focal ratio you desire, you'd have to have precise data from the manufacturer, and use an. Back focus is the distance between the last optical component of a telescope and the focal plane.
