About this image

After having read a few articles online regarding the possibility of capturing a Coronal Hole with an SHG in the Helium line I decided to give it a go myself with the Sol'Ex and 72ED. Nine scans at 32x sidereal reconstructed in JSol'Ex and stacked in Autostakkert, mild processing in Astrosurface, the Coronal Hole can just be made out when compared to the SDO image on the right.
