How about gifting your dad a membership to a museum of his choice? Most museums offer annual memberships that give access to exclusive events, discounts on their shop and café, and unlimited admission to their exhibitions. This can be a great way for your dad to enjoy all the exhibits that he loves, while saving money and supporting the museum. Alternatively, you could take him to a special exhibition he's really interested in and make a day of it together. This would be a great way to spend quality time with your dad while indulging in his interests.
Or you can get him a star map with the date when he welcomed you in this world.
