Yes, they are free!
The whole purpose of my astrophotography is to show others the wonders of God’s creation. I believe this can best be done by offering these images for free. Thus, I have not watermarked or copyrighted any of the images I have taken: everything is in the public domain. However, while not required, I would prefer that you give Fourth Day AP credit for them.
As I continue to upgrade my equipment, the quality of the images I collect will increase; if you don’t see any images you like, stop by later to check out any new images I may have taken!
“. . . Freely you have received, freely give”.
Matthew 10:8
