Most of the pages are in Japanese, but you can browse our images with English in the observation pages.

There are an increasing number of reporters upgrading telescopes 
and there are also many reporters using multiple telescopes, 
so updating the reporter's telescope data is difficult. 
Therefore, omit the information on the telescope from the title for each reporter.
