The return to St Aldhelms Head

So the jet-stream moved north, the clouds cleared and my first truly 100% clear night since I started this astro-photography mission happened upon me almost out of nowhere.

Typically this clear night is on a work night of course. Ignoring that though Shaun and I ventured out in the dead of night to catch falling stars in camera boxes on the cliff tops of the Jurassic Coast.

The trip went much the same as the last one with the exception that we knew where we were going and what we were aiming for only this time armed with a perfectly clear night. The shots below will be familiar, the only exception being that there are no clouds to obscure the view of infinity and it's heavenly bodies.
Next up is the resulting time-lapse video of about two hours shooting.

A bit noisier than I'd like so I tried using a program called Deep Sky Stacker to use the photos in the sequence to stack into a noise-free super single image.

My first attempt at using it(with some post-processing) can be seen below the video. It does give some nice extra detail in the galactic core of the Milky Way and along the band but it also causes other distortions, or emphasizes existing ones. I will need significantly more practice with it but it makes for interesting viewing as a first experiment.
