A 72-page sight reduction method logbook, with tabulated pages for recording the observations of both morning and evening stars. One of a series of onboard logbooks produced by Witherby Publishing Group.

This easy to use logbook 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 findings. A worked example is included as a guide for the user.
