NGC 7722 - Spiral Galaxy with Type Ia Supernova 2020ssf Berkeley 72 - Open Cluster NGC 2158 - Open Cluster (H VI-17) M35 - Open Cluster (NGC 2168) C/2019 L3 (ATLAS) - Comet C/2020 F8 (SWAN) - Comet (Attempted Sighting) NGC 2782 - Spiral Galaxy with Type Ia Supernova 2020scc UGC 6930 - Spiral Galaxy with Type Ia Supernova 2020rcq UGC 4052 - Elliptical Galaxy Pair (PGC 21993 & PGC 200239) UGC 4414 - Spiral Galaxy (PGC 23700) Variable Stars (photometric monitoring) - CI Cyg, S Cyg, SS Cyg, AM Her, BL Lac, FU Ori, DY Per, GK Per, RR Tau
- CN Ori, NV Ori attempts failed (dome issue)Nearby Stars (astrometric monitoring) - HH And, DX Cnc, Groombridge 34
- All night session (7.4 hours total) - Main aims of the session were the acquisition of a selection of deep sky targets, together with some variable star, nearby starand comet targets - Dome Issues affected the delivery of final few targets - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 4°C (min) - CCD Temperature: -15°/-20°C - Notes from 2020-09-28 >> -

| Berkeley 72 - Earlier Image (2020-09-04) Target only partially successful with several frames lost due to cloud & poor guiding issues. Target to be repeated. It's unclear from image below where the centre of the star clustering is so for time being the target offsets will be unchanged. |
