Night skies have always seduced me. Waiting for the right conditions requires patience, and UK skies aren't generally all that clear. You also need to factor when the moon is out, the best shots in the northern hemisphere are taken the first week of the month when there's no moon. I use a handy tool called Photographers Ephemeris to track when the moon will rise and set. The pictures shown here were taken over a two hour period, and comprise of about 200 images. It's the same process as doing a two hour exposure but without having to worry about noise being introduced into the image, and also saving battery life by not having to repeat the length of the exposure the camera requires to go through its noise reduction processing. I use software called StarStax to help glue all the exposures into one.
