Hi all

Some SHG morning sun Ha images attached & via link below.

I've also attached a dopplergram from one scan taken at 2310UT.

This was generated by creating two different images from the same scan by shifting the wavelength used by 0.4A either side of the Ha line.

In the image the red shifted data is moving away from us (but is shown as being blue in colour), and the blue shifted data (shown in red) is moving towards us.

I've also attached a negative version of the Ha image.

The doppler shifted image is an interesting option.

Thanks Maurice - I really like the first image, the third has a bit too much going on. Still interesting however. Cheers John W.
