Ha Full Disk With the PGR Chameleon 3 - 9th April

The extra image scale afforded by the larger chip and smaller pixels of the PGR Chameleon 3 suits the smaller focal lengths needed for these full disks, but also results in a final disk nearly 1500 pixels in diameter.  Poor conditions yesterday meant I didn't really have time to mess around with any settings, either on the camera or in terms of tuning the etalon.  This was taken with the triple stack 40mm scope at somewhere around 550mm focal length.
