During this time, the Directors of the Lick saw the documentation and analysis of eclipses as a core contribution of the Lick to the field of astronomy, both in attempting to answer the questions posed above, but also simply to record and archive the eclipses for posterity.
John M. Schaeberle designed a 40ft portable telescope that was used in different configurations for the majority of these expeditions. To defray costs, the Lick relied on volunteers in each location to assist with the setup and manipulation of the telescope and photographic equipment.
