| Notes | Seeing and transparency average. First image with the G11. Some guiding issues to work out, as well as I think some field curvature. This caused some slightly elongated stars on the left and right edges of the field. Some dust motes and misalignment of different night's frames caused me to crop more of the image than normal. |
