You can download the 2017 Air Almanac for free and it is even better than the Nautical Almanac, data is printed at ten minute intervals so, if you work it right, you can avoid interpolations.

You can download all three volumes of HO 249 tables for free compliments of Ken Gebhart, one of our members, the owner of Celestaire, the best place to buy your navigation equipment.

OR:
You could download an entire celnav system for free which includes a long term almanac good til 2019 for the sun and to 2016 for the stars. This method doesn't need the large sight reduction tables.
