Photographs were taken on 2000-Jan-03 and 2000-Jan-04 with the aim of imaging several asteroids (minor planets) including collecting evidence showing their gradual movement across the backdrop of stars (this exercise followed successful 1999-Dec-31 analysis of photo taken on 1999-Dec-06 showing 29 Amphitrite). 

Photos were taken using Pentax Camera mounted on top of LX200 telescope, with  300mm f8 lens and at various exposure times.  Images of Minor Planets 29 Amphitrite, 532 Herculina and 6 Hebe taken on successive nights show clear movement over 24 hour period.
