Notes | Seeing and transparency average. Flexure is causing elongated stars. The OIII channel VERY weak. Needed more time, but the location of my house reduced the night's data to only around 2 hours total. Couldn't get enough data (actually got lazy and tired of working on this one! ) so the image is noisy. |
