How about getting your husband a telescope as a birthday gift? He can use it to observe celestial objects such as stars, planets, and galaxies. Additionally, you can consider purchasing astronomy-themed books, magazines, or a subscription to a stargazing magazine to help him learn more about his love for astronomy. Alternatively, you can take him on a trip to a local observatory, planetarium or even book a stargazing night tour, where you both can experience the wonders of the universe together.
Or you can get him a star map with the date when he was born.
