Object Information                                            Imaging Details

Scorpius, the scorpian, is one of the more recognizable constellations in the southern sky. I actually looks like a scorpian (at least the tail). It's Scorpius (as legend has it) that killed Orion the mighty hunter. Both now have celestial homes. Scorpius sits opposite Orion in the night sky - Scorpius dominates the summer milky way; Orion dominates the winter.

The region contains a number of nebulae and star clusters including globular clusters M4, M19, M62 and M80. There are several open clusters including M6 and M7. There are also bright nebulae including M8 and M20.

This was one of my first DSLR images taken at the 2004 Texas Star Party. I wasn't able to get autoguiding working, so turned to doing some wide field imaging using my NexStar C11 to guide my Canon 300D. The image is a two frame mosaic manually aligned using Photoshop. The map (above, right) shows the FOV of the linked image.

Doing a mouseover of image above will show a stick figure constellation overlay. Clicking the image will bring up a higher resolution, wider FOV image.
