Default Milkyway Widefield

A widefield shot of the Milkyway from the Queensland Astrofest. Taken on a portable tracking mount, mounted on a camera tripod - exposure is just over 3 minutes. Lens was a 10-22mm Canon at ~10mm. Thanks for looking

Great shot...How does the tracking work? I mean for over 3 minutes, you have no blur, so I suspect it moves your camera in line with the stars due to our orbit. But as the mount moves the camera, you are able to not get too much blur on your foreground (or is that from an overlayed imaged?)

Thanks and sorry for the obviously dumb question.

Thanks for the comments. The lens used was a 10-22mm @10mm so even three minutes you will not see too much movement in the foreground (which is around 20metres away). The mount is "pointed" towards the south celestial pole, and the motor on the mount rotates it at the speed that is equivalent to the rotation of the earth. The mount was borrowed so unfortunately I cannot show you a photo of my exact setup, however I found a photo of the mount on the web ...



...and by the way - there are NO dumb questions, however this doesn't preclude dumb answers

Beautiful! I love the dark lanes from Antares to the galaxy center that are clearly visible in your photo!

Damn, I wish I could experience dark skies in the southern hemisphere. Have to rely on shots like this instead. Very very nice.

Thanks all for the feedback - much appreciated!

Adrena1in ... I should point out that the centre of our galaxy (and centre of the image) was directly overhead earlier in the night - you really should get down here one day.

Southern or northern hemisphere, I'd just like a sky that was dark enough to allow me to make a 3 minute exposure without overexposing the sky due to light pollution.
