| Imaged Double Stars | ||||||||
| Date: | 8. Sep. 2009 | |||||||
| The following table is a summary of imaged doubles with comprehensive data. | ||||||||
| The list will be completed with more doubles as the imaging continues. | ||||||||
| The color balance is difficult to achieve, so comments to other visual impressions are welcome. | ||||||||
| Also remarks about data errors and tips for more interesting doubles are very appreciated. | ||||||||
| PW is the angle between north and the connection line of the both stars measured to direction east. | ||||||||
| The orientation of the images is such that the bottom of the image shows to the horizon (naked eye view) | ||||||||
