    Golden Syrup artificial horizon
    From: Bill Lionheart
    Date: 2026 Jan 5, 15:48 +0100

    I am reading Alexander Olsen's
    Introduction to Celestial Navigation.  He advocates Golden Syrup (a sort of runny treacle or sucrose syrup, made from beet sugar as a biproduct and popular in the UK) for an artificial horizon.  More viscous than water so less succeotable  to wind ripples. Water soluable so easier to clean up spolls than oil.  Viscosity probably varies a fair bit with temperature.  Any thoughts on this?  The author sounds like writing from experience and photo seems to be on a ships deck but in harbour. 

    Bill Lionheart.
