Pixel scale and resolution in astrophotography - astrojolo
- https://astrojolo.com/gears/pixel-scale-and-resolution/
- We can calculate pixel scale for given setup with the formula below: scale [“/px] = 206.3 * pixel size [um] / focal length [mm] When we consider imaging setup it is good to find out what factors are limiting our capabilities and to to fight them back. For low pixel resolution setups (3-4 and more arcsec/px) optics resolution limit is of low imp…
Image Scale – A S T R O P I X
- https://www.astropix.com/wp/image-scale/
- What is the image scale? Image scale describes how many arc seconds of sky are covered by each pixel in the camera. Equation 1: Image Scale Per Pixel. P = (8 * S) / (FL) Where: P is the image scale per pixel in arc seconds ... For long-exposure deep-sky astrophotography, you are unlikely to be able to resolve 1 arc second because of variations ...

- 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: 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.
