Image capture:
Imaged with the Takahashi TOA-130NFB and QHY168c on 1/1/24. Attempted to capture M 108 together with the Owl nebula; however an error in camera rotation (+45 degrees rather than -45 degrees) caused the two objects to be near the top and bottom of the sensor with a small part of the Owl nebula cut-off. See the Owl nebular (M 98) for more details about the capture.
