That's a great interest! Here are a few ideas that your grandpa might enjoy:
1. Telescope: This is a no-brainer. A good telescope can be a real game changer for someone interested in astrophotography. Depending on his level of interest and experience, a telescope can range from a simple, handheld version to more elaborate models.
2. Book: A good book on astrophotography may be the perfect gift for your grandpa. There are many great books out there that discuss everything from capturing the perfect image to astronomical phenomena. Consider "Astrophotography: Essential Guide to Photographing the Night Sky" by Mark Thompson.
3. Astrophotography Prints: Consider ordering a few prints of some of the most famous astrophotos such as the Hubble deep field space image or one of the Milky Way Galaxy. Printed posters can be a great way to decorate his workspace or bedroom with something he really loves.
4. Subscription to an astrophotography magazine: There are plenty of online subscriptions to magazines that specialize in astrophotography, like Sky and Telescope Magazine.
5. Astrophotography Accessories: There are some accessories that can make astrophotography easier or more enjoyable. Consider purchasing your grandpa a remote shutter, photography filters, or an off-camera flash for his DSLR camera.
