Objects Session Notes
HD 5501 - Suspected Binary Eclipsing Variable SS Cyg - Variable Star NGC 7209 - Open Cluster CY Lyr - dwarf nova variable NGC 6781 - Planetary Nebula T Tau - variable M74 - Spiral Galaxy
- 2.1/4 hr session - CCD operation of -15 degC - main objectives where to acquire images of HD 5501 and SS Cyg as part of ongoing projects on specific variables - opportunity taken to acquire moderately long exposure images of M74 and NGC 6781. - More Notes
3 sets of measurements made in B, V, R filters as part of
ongoing study on variable behavior of this suspected eclipsing variable..
