An astronaut in a sleek, reflective suit stands on the tranquil shore of a moonlit lake under a starry sky, captured in crisp detail reminiscent of a Fujifilm XT3 photo. The scene is richly textured with 8k UHD clarity and enhanced HDR contrast. A glowing large neon triangle towers behind the astronaut, casting vibrant, colorful reflections across the water. The geometric figure pulsates gently, illuminating the surreal landscape around it. The atmosphere is serene yet surreal, with the neon light creating a mesmerizing play of reflections on the lake's surface under the night sky.
