    My first thoughts were to make 'just for fun' an improved ‘latitude stick’ using a digital Vernier calliper and tangent tables, finding one's natural arm’s length in the first instance by comparing the measured height of a planet with its calculated height.  However, I soon found it’s only repeatable at full arms length, so it would only work for the small heights you probably wouldn’t want to use for celestial in any case.  I decided to wait until the weather warms up before testing the idea further.  Living inland, the horizon would have to be an led at eye height on a gatepost.  DaveP
