Description

This my first effort imaging the full disk of the sun.  Since my setup FOV is not large enough, this is a 6 panel mosaic.  I found creating a suitable flat to be difficult.  Since Ha light is needed to penetrate the Quark, the sun is used as the light source.   People suggested using a white plastic grocery bag to diffuse the sunlight for the flat.  This still let sun features come through.  I doubled the bag and reduced the exposure and finally got a decent but not perfect flat.  I inverted the image for processing with AutoStakkertt!, IMPPG and of course Photoshop.
