Direct CCD Exposure Time Calculator 1.0
Calculates the observation time needed for a given telescope, instrument, detector and filter.
Algorithm based on the IRAF task ccdtime
|Magnitude:||(must be between -5 and 35)|
|Signal/noise:||(must be between 0 and 100,000)|
|Seeing (arcsecs):||(must be between 0 and 5)|
|Airmass:||(must be between 1 and 3)|
Your observation will require approximately seconds to complete.
