Mu Cepheus

The run of good weather has continued and last night stayed clear so I stopped up late enough to grab some pictures of the Mu Cepheus area of the Milky Way. The trouble with being at 52 degrees latitude is the endless twilight at this time of year. While it’s getting better by the day it’s going to be next month before we start to see skies that can be classified as dark.

So, with the sky still pretty light I took 10 5 minute exposures with my QHY9C behind a Canon 75-300mm zoom set wide open at 135mm. Flats had to wait until tonight as the fuse blew in the cable to my EL panel.

This is a re-processed image as I was unhappy with the first one. I cut the first two frames from the sequence as these were worst affected by the light sky, especially in the lower left corner. The colours are rather more muted in the nebula but have been preserved better in the stars.
