Sam,
Here is a table from H.O. 208 Dreisonstok which is a very quick single entry table to correct refraction and parallax for a bubble or superimposed artificial horizon Moon observation.
Example for Moon this evening:
10/5/2014 UT 01:49:12 Moon AH superimposed 34° 10.4' N 119° 13.8' W
AH Hs 57° 40.7'
0.0 I.C.
57° 40.7' / 2
Hs 28° 50.3'
Ref Px +51' (HP 60) see attached table
Ho 29° 41.3'

I figured it all out and just did 3 more Moon sight with very good results.
Hs was corrected for IE, Refr, Parallax and SD using the formulas Sean mentioned earlier today.
To check my Hs correction I also used Navsofts "Moon Corrections" pdf which provides one Hs correction figure when entering the table with HP and Hs. That's a pretty fast method.
