The Subaru Telescope, located at the summit area of Maunakea, the Island of Hawai‘i, is equipped with a high-sensitivity, high-resolution All-Sky Camera whose images are continuously updated on the Maunakea Weather Center website. Following the “Centennial of the Planetarium × 25th Anniversary of the Subaru Telescope” nationwide online event held on October 19, 2024, in Japan, we reprocessed these image data into a dome master format suitable for planetarium projection. The processed data were archived and made accessible through a new system on the Nagoya City Science Museum website, in collaboration with the National Astronomical Observatory of Japan (NAOJ), enabling planetarium professionals across Japan to use these materials. An English version of “The Public Archive System for the Subaru All-Sky Camera Images on Maunakea” website is also available for international planetarium community like the International Planetarium Society (IPS).
The collaborative event began at 2 p.m. in Japan, which was 7 p.m. in Hawai‘i, just after sunset on Maunakea. Selected real-time All-Sky Camera images were edited for a full-dome projection and shared immediately with all 25 participating planetariums and science facilities. Each of these facilities projected the same images simultaneously, allowing all participants across Japan to share the experience of enjoying the live night sky over Maunakea, including the Milky Way, Venus, and Comet Tsuchinshan-ATLAS.
The Subaru Telescope's All-Sky images are highly compatible with a full-dome planetarium. Any planetarium professionals can access the public archive system for Subaru All-Sky Camera images of Maunakea, and download and project almost real-time images of Maunakea for free, without any effort of extraction or conversion. This system provides a practical model for connecting planetariums with an astronomy research facility, allowing the public to view real-time, exclusive images from world-class observatory locations.
