Astronomical Corrections

This frame has calculations for Angle of Separation, Refraction at horizon and Nutation and Aberration Correction. 

 

I have not found a good source to verify the high accuracy Meeus formulation, so I have highlighted it as unverified and show for indication purposes only. I am using Meeus's lower accuracy formulation for all other corrections as it was verified. 

 

Inputs and Outputs for Right Ascension/Declination in either decimal degrees or HH:MM:SS for RA and Deg:MM:SS for Declination now allowed.

 

 

 

This screen has the RA-Dec box checked and the Equatorial inputs/outputs are in Hours/Minutes/Seconds and Degrees/Minutes/Seconds instead of degrees.
