Skybox shader - how to deal with transparent texture?

Hello, I’m trying to do skybox shader with stars and moon. My sky gradient is a one subgraph stars are on second subgraph and my moon is on third one. I’m using Sample 2D Texture Array for moon as I have a few moon pics with different phases. My problem is that my texture is a little transparent in bright side and is completly transparent on it’s dark side (it is a dark/black color on my texture, there is no transparency on the moon part) and I can see stars on the dark part of the moon and also I can see that they glow a little through the bright side. How can I completly remove transparency from my texture array to prevent stars glowing through the moon?
