20140720 Sun Ha


The camera that I used wouldn't cover the whole Sun, it has an even smaller sensor than the 2014 07 17 Sun image. On the plus side, this is a 16-bit camera, versus the 8-bit in the Imaging Source camera for the 17 Jul image.

Only saved the red channel when capturing. Converted to a grey-scale image when processing, turned back into a color image at the end.

North is up.
