Session Notes

Basel 7 - Open Cluster     NGC 5496 - Spiral Galaxy NGC 5674 - Spiral Galaxy     SHK 360 - Faint Galaxy Group (PGC 1272444 et al)     Variable Stars (photometric monitoring)   - SY Cnc, FU Ori, NV Ori, RR Tau - CN Ori attempt failed due to cloud     Nearby Stars (astrometric monitoring)  - None - Groombridge 34 and Teegardens Star attempts failed due to wind

- All night session (8.9 hours total), , but shutter closed through middle of night due to cloud. - Main aims of the session was to  acquire images of a selection of deep sky and comet objects     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  1.5°C (min) (Dew heaters on auto) - CCD Temperature:  -20°C  (58% av. power) - Notes from 2020-02-27 >>

Basel 7 - Open Cluster

Basel 7 (Monoceros) SAC Basel 7, Saguaro Astronomy Club Database Target offsets of 3.7' W, -0.8' N  used to place the center of star clustering at image center.

CCD Image (70% size, linear scale) 3 x 30s exposure (average combine), 3x3 binning, C Filter 2020-02-27 22:02 UT (#757089-97) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2

Basel 7 - Earlier Image (2020-02-13 pm) Target offsets of 3.7' W, -0.8' N  used to place the center of star clustering at image center.

Basel 7 - Earlier Image (2020-02-02)

CCD Image (70% size, linear scale) 5 x 30s exposure (average combine), 3x3 binning, C Filter 2020-02-02 00:09 UT (#749133-41) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2

Basel 7 - Earlier Image (2020-01-26) Although the image is centered on the target object 'SAC Basel 7' in TheSky6 the center of star clustering appears to lie slightly to the right of center.
