Description

Captured during the short and bright nights between 9 June and 3 July. This is my first tri-colour narrowband image and it has taken me a long time to achieve a satisfactory colour balance with the Hubble palette. The initial processing was in Pixinsight then colours were adjusted in Photoshop CS2 and finalised again in PI. It is a bit noisy if you look too close but not bad considering the sky brightness at 53 deg N this time of year.
