Neptune & Triton

My first image of Neptune. In this image I exposed Neptune in prime focus because it only has a magnitude of 8 and so focusing on it at higher magnifications is difficult. I was however able to capture its moon Triton too with a little longer exposure and do a composite image. The color difference beween the planet and the moon is clearly visible, with Triton having a violet-brownish hue.
