WebAug 13, 2013 · The focal length is the distance between the pinhole and the film (a.k.a. image plane). For reasons we'll discuss later, the focal length is measured in pixels. In a true pinhole camera, both \(f_x\) and … WebSimply enter the telescope's focal length, the camera's pixel size and your sky's seeing conditions to determine if they are a good match :-) A few notes: We are assuming OK seeing is between 2-4” FWHM and a resolution between 0.67” and 2” per pixel is the sweet spot. Over 2” is under-sampling and under 0.67" is over-sampling.
