Objects Session Notes
NGC 7025 - Spiral Galaxy W And - Mira variable V Sge - Variable Star (Type E+NL) Astrometric & Photometric Monitoring - U And, W And (mira variable)
- BL Lac (blazar)
- RX And, Z And, RU Peg, R CrB, U Sge (variables)
- Ross 248, 61 Cyg (Nearby Stars)
Attempts at SS Cyg, V2491 Cyg, AM Her, Groombridge 34 failed due to cloud
