Jackson,
Solar still hooch is rumored to be the finest upon land or sea. An eye patch is required before consumption or navigating I was told ;-)

Greg:
Did the sun appear "a tad fuzzy" due to the effect of the solar still?
If so, then one could conclude that the sharpness of the reflected image of the celestial body is inversely proportional to the effect of the product of the solar still on the observer.

The coffee can lid improvised artificial horizon continues to evolve. The latest modification is a clear plastic A frame greenhouse that acts as a windshield (see attached image). The greenhouse plastic is from a discarded plastic container. Careful cuts and taped seams make for a stable structure that fits perfectly over the water tub. It is necessary to remove the greenhouse from the water tube immediately after each celestial observation to prevent interior fogging. It turns out that a solar still has also been created by accident.
Trials have been in the plus or minus 1 minute of arc range with the reflected Sun appearing a tad fuzzy. Glass would be better but not as handy.
