Basel 10 - Open Cluster

Basel 10 (Perseus) SAC Basel 10,  Saguaro Astronomy Club Database Although correct target offsets used (-5.0' W, -1.1' N), a rogue jog on the final centering operation caused a 3' pointing error led to the centre of star clustering to not be precisely centered. Target to be re-imaged in a follow-up session

CCD Image (70% size, linear scale) 8 x 30s exposure (average combine), 3x3 binning, C Filter 2020-04-01 20:14 UT (#765004-11) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2

Basel 10 - Earlier Image (2020-02-12) Although the image is centered on the target object 'SAC Basel 10' in TheSky6 the center of star clustering appears to lie to the left of center. Note: Target to be re-imaged in a follow-up session using target offsets -5.0' W, -1.1' N

CCD Image (70% size, linear scale) 7 x 30s exposure (average combine), 3x3 binning, C Filter 2020-02-12 20:21 UT (#751087-94) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2
