One idea could be to sign him up for a subscription to a streaming service that offers documentaries, like Netflix or Hulu. Another idea could be to put together a documentary-themed gift basket, including a few of his favorite documentaries, some movie snacks, and maybe even a nice blanket to keep him cozy while he watches. You could also consider a book about documentary history or a coffee table book featuring photography from documentaries.
Or you can get him a star map with the date when he was born.
