Partial solar eclipse in Ha

About this image

A single frame from an SER video captured at 11:22:25 after maximal eclipse. Frame exported from SER Player and curves adjusted in FastStone Image Viewer. The frames during the maximal phase of the eclipse has wispy clouds drifting through the field of view. There is a slight gradient on the disc of the Sun, but work is on going to lessen this and I now think it is mostly due to not nicely tuning the primary etalon before adding the second one.
