How about a high-quality charcoal drawing set or a set of premium charcoal pencils and paper? You could also consider a charcoal drawing guidebook or a subscription to an online art tutorial service that specializes in charcoal drawing. Another idea could be commissioning a professional artist to create a custom piece of charcoal art based on one of your dad's favorite photos or even a portrait of him.
Or you can get him a star map with the date when he was born.
