72-page easy to follow and clearly laid out Sight Reduction Logbook, with tabulated pages for recording the observations of both morning and evening stars.
The easy to follow format allows for the computation of a 7 star fix at morning or evening stars in typically 12-15 minutes from taking the observation of the last star to plotting the position on the chart. For each observation there is a separate plotting sheet to record all of your findings.
