A perfect gift for your husband could be a set of non-fiction books. You could browse popular titles in his favorite genres or explore books from his favorite authors. Additionally, you could consider a Kindle e-reader, which would allow him to easily download and read new non-fiction books on-the-go. Another option is to give him a subscription to a magazine or online publication that specializes in non-fiction topics that he's interested in. This would provide him with fresh and engaging reading material each month.
Or you can get him a star map with the date when he was born.
