Here’s an awesome sequence of images from skyscape photographer Miguel Claro. These images were captured from Cape Espichel, Sesimbra, Portugal, about 40 km away from Lisbon. This triple sequence poster contains a beautiful widefield view of the well-known winter constellations visible from the northern hemisphere; then a zoom in to focus on Orion; then Claro zooms in even more to find the Great Orion Nebula M42 and M43.
Claro took a single shot for each image with a DSLR camera, using between 10, 35 and 300 mm. “To do this work I´ve used the incredible Vixen Polarie mounting travel, to avoid the Earth rotation, and a Canon 60Da, a camera sensitive to the infrared/H-alpha wavelengths,” Claro said.
The above image is a four hour exposure of star trails, not altogether unusual,
......except the image can be wrapped into a 360 degree panorama.
The image was taken near Mudgee in NSW Australia. The original data files are
now available as a Quicktime VR movie (note WIndows users will require Quicktime player for windows)
It shows the relative motions of stars in the sky around the Southern celestial pole (circular),
near the eastern and western horizons (near vertical streaks),
and toward the Northern pole (arcs centered on a point below the horizon)
Reddening of the stars as they approach the western horizon is also evident.
The near vertical red arcs at the centre and far left of the image are the navigation lights of a passing jet aircraft.

Well, it does show that I am on the right lines, doesn't it?
By the way - I'm loving the course on YouTube.

PS. I've just thought to ask for ideas on how to best use the Search facility on the Apod site. Before posting the image above, I put the photographer's name into the search box, like this, "David Ward". A 'nothing found' message came up.
What would have been a better search technique?
Many thanks
Margarita

"Making the invisible visible" - the ISS Image Frontier
from Christoph Malin
This is a tribute to the International Space Station Program as well as Dr. Don Pettit, NASA Astronaut and ISS Astrophotographer. It can not be emphasized enough, how Dr. Pettits innovative photographic work and his passion has changed the way we see earth from space. Accompanied with great info on the challenges of astrophotography aboard the ISS by Dr. Pettit, the shortfilm features a great compilation of 4 timelapses ("intro", "startrails", "fisheye" and "aurorae"). Now welcome aboard the ISS - enjoy stunning photography and timelapses from the Space Station!
