Session Notes

NGC 5707 - Spiral Galaxy (LGG 384 Member) 68P/Klemola - Comet IC 1029 - Spiral Galaxy (LGG 384 Member) NGC 7250 - Spiral Galaxy ("Starburst Galaxy") NGC 599 - Elliptical Galaxy Whiting 1 - Globular Cluster     Variable Stars (photometric monitoring)   - RX And, U And, Z And, SS Her, BL Lac     Nearby Stars (astrometric monitoring)  - HH And, Barnards Star, Groombridge 34, Teegardens Star

- Full night session,  Duration 7.0 hr Session operated in fully automated mode. Intervention required after Job Executor stalled waiting for program execution to return from a Telescope.Jog command. - Main aim of the session was a full night of general observing with a mix of variable stars, nearby stars, comets and deep sky targets.     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  Initially 16.5°C falling to 15.0°C  (min) / then 14°C  (min) in observatory (Dew heaters on manual ) - CCD Temperature:  -5°C  (62% av. power) & -10°C  (73% av. power) - Notes from 2019-08-25 >>

NGC 599 - Elliptical Galaxy

NGC 599 (Cetus) NGC 599 (catalog mag +13.5),  NGC 601 (catalog mag +15.1)  PGC 3093506 (catalog mag +16.3) Target was shot by mistake. The intended target was ARP 4 (also in Cetus) but ARP 4 in TheSky6 points to NGC 599 for some unknown reason.
