After reading about Gary J. LaPook's memory feat I had an idea: On the reverse of the COT scale of my Bygrave Slide Rule I printed the dip and altitude corrections (for stars), temp. & pressure corrections, the SHAs & Dec. of all 57 nav stars for 1 Jul., the GHA of Aries for 1 Jan. plus the daily/hourly increase & finally, the Bygrave instructions.

Now I have a complete emergency almanac for the stars and sight reduction system on 1 & 1/4 pages. (I cut the COS scale down to 1/4 page to make it easy to slide around.)

I'm assuming you chose the stars based on a good distribution in the sky and also on magnitude. So which stars did you settle on? (And did you choose only for the northern or southern hemispheres or both?)
