Part of the Moon
I really tried to take a photo of the moon with my 200mm lens (which is around 300 on my crop sensor camera) but the moon was always so small on the photo. So this time I attached my camera to a Celestron CPC 1100 GPS (I'm not 100% sure about the type) telescope which is 2800mm. I still think that the photo could be sharper, but for a first try I think it's quite good :)
I took three shots, but Photomatix was not able to properly align them, so I created a HDR from a single RAW. It's also converted to B&W as it had this yellowish color, which I didn't liked at all.
