Scan time for Sol'Ex

The scanning of the solar disk using a Sol'Ex can be calculated using following formula

T = 8.79 * P / (f * v * Cos (delta))
  • T = exposure time in s
  • P = pixelsize in micron; include binning
  • f = focal point of telescope in mm
  • v = scanning time of telescoop, typical 4, 8, 16
  • delta = declination of the sun
It looks like that the outcome of the exposure time compared with the scanning time is rather exponential.
