Berkeley 43 - Open Cluster

Berkeley 43 (Aquila) Berkeley Catalogue Note: Target imaged using target offsets of W 1.6', N: 3.8', in order to position the centre of the star clustering at the centre of the image.

CCD Image (70% size, square root scale) 4 x 30s exposure (average combine), 3x3 binning, C Filter 2020-09-03 21:21 UT (#804032-38) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2

Berkeley 43 - Earlier Image (2020-08-31) Centre of star clustering appears to be offset from the Berkeley Target Coordinates Target to be reimaged using target offsets of N: 3.8', W 1.6'

CCD Image (70% size, square root scale) 9 x 30s exposure (average combine), 3x3 binning, C Filter 2020-09-03 23:15 UT (#804130-38) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2

Basel 10 - Earlier Image (2020-04-23) Note: Target imaged using target offsets -5.0' W, -1.1' N in order to position the centre of the star clustering at the centre of the image.

CCD Image (70% size, linear scale) 8 x 30s exposure (average combine), 3x3 binning, C Filter 2020-04-23 01:58 UT (#772232-39) 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

Berkeley 72 - Open Cluster

Berkeley 72 (Orion) Berkeley Catalogue 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.

CCD Image (70% size, square root scale) 3 x 30s exposure (average combine), 3x3 binning, C Filter 2020-09-04 01:52 UT (#804264-70) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2
