Startrail around polarstar

The sky is clear and I'm on holliday. So what do you at evening? Yes, watching the sky and more specific taking some pictures of Iridium flares and trying out making a startrail.
Picture below is build up from 62 pictures each 30s exposure time, ISO 100 with Nikon D60 18mm with 30s between each photo. The first picture is edited using CS4 and "lighten".
The second picture is edited using the software Startrails - see Startrails.de website.
With a full moon and some minor clouds conditions were not optimal but as a first try out...



Edited with CS4 - 62 pictures Nikon D60 30s ISO100 18mm

My First Solargraph


Today, after six months I opened the solargraph. The can was still intact and the photopaper was well preserved. The paper was humid and still fixed against the wall of the can. Looking at the picture you will see some interesting aspects. In the front (at the bottom of the picture) you see my garden with the trapoline in the middle and the trees some further.
Also the top of the sunpaths is not captured on the picture. On the inverted pictures the many black band show the poor spring without "sun".
