Bullet 61 Cygni - Star (the 'flying star')
Bullet SS Cyg - Variable Star
Bullet PGC 67235 - Spiral Galaxy
Bullet Barnard's Star
Bullet Groombridge 1830 - Nearby star
Bullet M106 - Spiral Galaxy
Bullet NGC 3953 - Spiral Galaxy & Supernova 2006bp
Bullet HD 209458 (Osiris) - Star with Extra-Solar Planet
Bullet AXP Monitoring (4U 0142+615 & 1E 2259+586)
Bullet HD 5501 - Suspected Binary Eclipsing Variable
- 2 hr 20m session 
- bright sky due to astronomical twilight conditions. moon 47% phase at 6 to 22 deg altitude
- main aim was to acquire images of selected nearby stars for ongoing proper motion / parallax studies and images of SS Cyg for ongoing variable star studies
- opportunity was taken to acquire improved image of M106, follow up images of SN 2006bp, and positioning tests on HD 209458 and HD 5501 which will be subject of future detailed studies.

AXP Monitoring (4U 0142+615 & 1E 2259+586)

Two Anomalous X-ray pulsers (AXPs),  4U 0142+615 and  1E 2259+586 (both lying in Cassiopeia) were checked for brightening. No indication of activity was observed at location of either AXP.   [AXP stars project
