Flats and Fits LiberatorThis is usually the last task of the night. The following morning, I will then take my flat images, but they can be done at anytime providing the focus and camera orientation are maintained throughout. This is really important, so usually, I take the scope off the mount at night, put it onto a flat surface and don't touch anything until the flat frames have been acquired.
- Stretching a white T shirt over the end of the telescope.
- Use an LED tracing/drawing board to give an even light covering over the end of the scope.
