I had to get out under the stars at least once during International Dark Sky Week. I headed back to the pine forest that was completely burnt out by a bushfire a few months ago. It is quite eerie walking amongst all the bare trees.
25/04/2014 19 image all sky panorama. Canon 5D MkII, 14mm, F/2.8, ISO 3200, 19 x 30 seconds. It was only after I stitched the images together that I noticed the bird like pattern made by the trees against the sky.
Thank you so much Yes the sky has moved a bit from the first to the last photo and in this case it would have been about 10 minutes between the first and last photos, but my panorama stitching software does a great job off interpreting each photo and warping the photo to match it's neighbors if needed. Even so you can end up with a visible stitching error sometimes, which is why when I do these particular shots I start and finish is a fairly featureless area of the scene so any errors are not through a focal point of the image. I would never start and finish at the central bulge of the milky way for instance.
Hello Alexander, Apologies for the late reply. Been very busy with packing for a house move lately. To answer your questions: - The further you can get away from Light Pollution the more detail you will be able to see (and photograph) in the Milky Way. I currently live about 60 kilometers from the nearest town.
- High ISO is normal for landscape astrophotography using a normal tripod as you need to "freeze" the motion of the stars. Read my tutorial here on the 600 Rule: www.capturingthenight.com/astr… The 600 Rule will tell you what your maximum shutter speed can be so it is then down to fast apertures and high ISO's to get the right exposure. Some cameras are better at handling high ISO's than others. Full frame cameras are best.
- You misunderstood my description: this is a panorama or mosaic made from 19 images. Each of those 19 images was of 30 seconds in length. 30 seconds is the shutter speed I use for that particular camera and lens combination (according to 600 or less rule). I do not have a lens that would cover that same field of view in one image. This is even wider than a so called "fish eye" lenses field of view.
