A Duo of Disks - Ha 18th July

A pair of Ha full disks here, both taken with different setups, and both processed quite differently.  The top disk was taken with the trusty Coronado DS40 scope, at 650mm focal length with the PGR Blackfly IMX249 GigE camera.  This is a positive image with false colour added.  The second was taken with the ED80 scope and Daystar Quark at around 1950mm focal length, again with the same camera.  This image has been inverted and false colour applied.  It is interesting how the different presentations make the different features on the sun stand out more.
