| 02.09.2021 | 21:00 | 00:15 | Rainer | Test with CWPI as the connector between CGEPro and Maxim DL -> works good but new alignment and slight rebalancing was necessary (**precise balancing is crucial for a good performance of the CGEPro**) => pointing is good, tracking is ok, still some small image shifts - further optimizations of the balancing necessary! |

| 28.07.2021 | 21:00 | 01:00 | Rainer | Telescope balanced; new alignment; observation aborted because of bad weather -> no new polar alignment, no tracking test, the pointing is good though; new driver for the QHY600M -> 4x4 bining possible, the current setup without the BAADER USB hub requires conservative USB traffic settings for the driver: reduced from 50 to 15; new park position for the telescope -> review and validation necessary, Maxim DL updated |
| 23.07.2021 | 21:00 | 02:30 | Florian | Taking flatframes during dusk; Imaging M27 & M57 >> due to consequent calibration failing no off-axis guiding this time. Tracking is miserable without guiding, however the pointing is quite accurate. Lucky Imaging of Jupiter |
