Generate a highly detailed, photorealistic image of a miniature collectible astronaut figure. The figure is depicted in a state-of-the-art, pristine white spacesuit with intricate paneling, a reflective gold visor, and subtle accents of lunar dust. This astronaut figure stands prominently on a sleek, black circular display base with a subtle texture. The environment is a meticulously rendered lunar base, featuring modular habitats, a science rover, and rocky terrain under a twilight sky. In the background, a vibrant and detailed spiral galaxy nebula is visible, adding depth and grandeur. The overall image should have professional studio product shot lighting, emphasizing the figure with cinematic quality, exceptional depth of field, and sharp focus on all elements of the collectible.
