Wide Field Astro: Fujifilm XT-1

We recently spent a few nights at St Andrews Beach in Victoria Australia. This provided me with some nice dark skies to try out my new "wide field" technique.
My new Fujifilm camera has a low noise sensor, this allows me to use a fixed tripod instead of a tracking motor drive.  As field rotation is now in play, your exposure time is of course limited, I can use around 7 secs with a 28mm lens, probably more depending on where your camera is pointed, near or far from the Celestial pole. The nearer the pole the less rotational movement.

I was quite surprised how well this one turned out.

Same settings as for 200mm above but at 25600 ASA. The stars begin to elongate sooner the further away from the celestial pole that you point your camera.
