Taken with a modified Canon 60D at 800ISO. 300mm f4 IS lens @f5.6. 14 x 30 second subexposures.
Tracking wasnt working well (I forgot to level the mount!). Really could have done with longer exposures.
The bright star to the left is Xi persei and its UV emissions have excited a nearby cloud of ionised hydrogen to emit at 656.4nm.
