Optimal pixel size range

Optimal pixel size range

Based on the statement that a separate representation of objects is only successful if there is at least one more pixel between them, the formula can also be used for the optimal pixel size range for a given telescope focal length and given FWHM-value range.

If the lower and upper limits of the existing seeing are used for the image scale βFWHM (for Germany 2" - 4"), the optimum pixel range for the telescope focal length can be determined in this way.
