 The night was dark and clear, and the high clouds had moved on. The comet is now forming a stunning composition with the Perseus arm of our galaxy, known as the Perseus Association. Seen here is the comets coma, with the very dim blue wisp of a tail that has disconnected moving off to its upper right. Alpha Persei is the brightest star in this field, and the third magnitude comet is now entering this rich star field which resembles a star cloud full of gold and blue stars.

I encourage you to view the largest image, the detail is worth the download.

This was with my Canon L lens set for 100mm FL, and stopped down to f/5 for sharpness.
