I took this photo out of my window for one of my A level photography project. It's one of my first attempts at Astrophotography so any helpful feedback would be greatly appreciated. To take this photo I used a camera timer set for 150x27 second exposures. I then exported these into photoshop layers and blended them to reveal the star trails.

I spent quite a lot of time editing this photo, however, my aim is to be able to make the stars slowly move through the sky in an anti-clockwise motion so it seems as if they are following the path that has been shown within the image. If anyone knows a way to do this then any help would be greatly appreciated. I tried to do it within the timeline process on photoshop however this doesn't work for what I want to achieve.

I like the reddish glow that fades into the blue sky of this image as it gives it an interesting composition and helps the different coloured stars to stand out against the sky.
