Blurry moon pictures on my iPhone 15 Pro Max

so i just got the iPhone 15 pro max on Verizon a couple months ago. was really excited about being able to taking moon pictures and they were really good the first week or so but then just recently tried taking more pictures and could not get a clear picture no matter what i tried. just a blurry moon as if i was taking it in 1X. note that the zoom goes to 25X. they really need to look more into it instead of throwing out more and more features.
