Objects Session Notes
61 Cygni - Star (the 'flying star') SS Cyg - Variable Star M3 - Globular Cluster Barnard's Star NGC 6905 - Planetary Nebula HIP 67593 - Nearby star R CrB - Variable Star
- 3 hr session
(+ 1 hour pre session sky flats)- bright sky due to astronomical twilight conditions - opportunity was taken to acquire images for astrometric analysis of several nearby stars. - More Notes -
Astrometric measurements made, as part of a ongoing study to attempt to measure proper
motion and annual parallax of 61 Cygni.
