CCD Session S00096 Notes from CCD Session Vega - Star RR Lyrae - Variable Star Delta Cepheid - Variable Star (Cepheid) AXP Monitoring (4U 0142+615 & 1E 2259+586) M56 - Globular Cluster
- 2.9 hour session, calm (no wind)
- Sky conditions deteriorated after 2 hours and forced the session to eventually
finish
- Aim of session was to record baseline images on RR Lyrae (RR Lyrae type
variable) and Delta Cepheid (Cepheid variable)
- Opportunity was taken to record images of M56 and monitor AXP stars in
Cassiopeia
- An attempt was made to make a mosaic over part of Hydaes cluster (Taurus), but
was unsuccessful due to developing cloud.
