Description

Now this is my first 'intercontinental' image. It started in Europe and ended in North America. A somewhat careless behavior led to large offsets between the datasets in the x-axis, therefore i had to crop the final image a lot. This should have given me an early warning what to expect: With expectations flying high, the data processing proved painfully difficult: it took countless attempts just for background extraction, but i never found out what is really out there and what is just artifacts. With an ambitious 'There must be more' in my mind i struggled on and this is what i ended up with. It does not really meet all my expectations, but i learned a lot about the limits of my skills.
