David,
You stated,
" The observer is in space and body ( horizon ) is at surface of the earth. Therefore horizon refraction is opposite sign but of magnitude you would have for body with altitude of dip."
This is correct so a refraction correction of 34' would be added rather than subtracted. This would change my previously posted dip of 18* 42 '(uncorrected) to 19* 16'.
