WebOct 20, 2024 · 2 microns / focal length (microns) = 20 mm / 100 m, focal length = 10 mm Figure 1 Design engineers need to either pick a focal length or a pixel size, then … WebPixel scale is a measurement of how much of the sky is covered by one pixel. Image Scale (arc-seconds) = 206 * Pixel Size (microns) / Focal Length (mm). When using our calculator you you don’t need to understand the theory or the maths. Simply 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: 1. We are assuming OK seeing is between 2-4” FWHM and a resolution between … See more For a star to retain it's round shape when viewed on your screen or photograph it’s diameter must cover a sufficient number of pixels. Too few and the image will be 'under-sampled’, the stars will appear blocky and angular'. … See more In the 1920s Harold Nyquist developed a theorem for digital sampling of analog signals. Nyquist’s formula suggests the sampling rate should be double the frequency of the … See more It is better then to image with a resolution 1/3 of the analog signal, doing this will ensure a star will always fall on multiple pixels so remain … See more dyson airwrap long gift edition
