How about a limited edition art print from one of his favorite artists? You can choose a piece that you know will resonate with him, or if you're not sure what he would prefer, look online for recommendations or talk to a local art dealer. You could also consider getting him a book about his favorite artist or a book on art history or criticism to deepen his understanding and appreciation of the subject. Another option could be to take him to a local art gallery or museum, which could serve as a great bonding experience between you and your dad.
Or you can get him a star map with the date when he was born.
