Ready to shoot...

Description: This is the very first image taken with my new 400 mm F/3 Dobson telescope (with its thin meniscus mirror). It shows the Moon which is partly lit directly by the Sun, and partly (dark side) by Sun-light that is reflected by the Earth.

A short exposure (1/125 sec) was used for the bright crescent, and a longer one (1/10 sec) to catch more detail in the shadow side. The two images were then combined with Photoshop, resulting in this 'HDR'-image. However, the visual appearance was even more impressive.

Watch this space.
