How about getting your dad tickets to an opera show of his choice? You could also consider giving him a classical music CD featuring an opera performance or a book about the history of opera. Another idea could be to give him a personalized gift such as a mug or a t-shirt with an opera-related quote or image. You could also consider a subscription to an opera magazine or newsletter.
Or you can get him a star map with the date when he welcomed you in this world.
