I've tried the 2013 Reed's Almanac. One annual volume of 68pp contains Two pages per month with two hourly GHA & DEC for Sun, Aires, Planets, Stars with two hour increment tables. Compact corerction tables reduce calculation a little. Hc & Zn use Vers ZD= Vers LHA x Cos LAT x Cos DEc + Vers( LAT+/- DEC) and ABC tables for Zn. Tables are Vers (Nat & Log) and Log Cos plus ABC.
I found they took longer and were more error prone than the air tables but obviously more compact.
Hope that helps.
