How about a DVD or Blu-ray set of his favorite historical movies or documentary series? You could also consider a subscription to a streaming service that has a great selection of historical films, or a book about a historical event or period he's interested in. If he's tech-savvy, you could make him a playlist of documentaries from YouTube, or suggest he download a history podcast. Lastly, if you want to go all out, you could even consider taking him on a historical tour of a nearby city or museum where he can learn even more about his favorite topics.
Or you can get him a star map with an important date you share.
