Epsilon Cassiopeiae (bright star lower centre) and Greg's Lambda in Cassiopeia.


Epsilon Cassiopeiae and Greg's Lambda by Greg Parker, on Flickr

[Greg Parker]

I am sorry for the mess I have made in trying to post the Epsilon Cass image I made the image VERY small (something less than 400k) and loaded this into Flickr. So why when I link to the Flickr image it comes out at nearer 900k I have absolutely no idea. Please delete one of the images and please make the other one less than 500k.

Greg, if you enable sharing from your Flickr options, it will let you copy and paste some BBCode that automatically utilizes a thumbnail version of your image and then links to the large version.

Hello, i'm Andrés, from Spain. I will try to make my first submission here (it took me a few days to find the "full editor and preview").


I took this one last friday, 30 april in north of Granada, Spain. I had not been happy with my first attempt to capture the Airglow, so looking away from any light pollution - free area to a second... failure, I found this wheat field in which I could capture a much rare astronomical phenomenon. Due to the rotation of our planet, every day the Sun disappears hidden by the plane of the horizon or - as in this case - the oaks which vegetate on this plane, leaving half the planet in darkness and illuminating the other half. The phenomenon is called sunset, and it is only possible to observe once every (more or less) 24 hours
