flame star IC405 to the ′′ pond ′′ IC410,

In order to shoot the comet, QHY268C was specially adjusted to high gain mode, Gain 56, Offset 10, with a 100-second short exposure to prevent the comet from dragging. As a result, the comet was captured, but the camera hung up, the infinite card read out, and had to return to the factory for repair. Now, even the equatorial meter is starting to go crazy for unknown reasons.
It seems that the comet is really a broom star......
