How about a personalized photo book? You could gather some of your dad's favorite nature photos and put together a book filled with his best shots, along with some meaningful captions or quotes. Alternatively, you could also consider gifting him a high-quality camera lens or a photography workshop or tour that specializes in nature photography. Additionally, a subscription to a nature photography magazine may also be appreciated.
Or you can get him a star map with an important date you share.
