Starting to get some OIII data for my Veil Nebula mosaic. Here's a crop of one pane containing "Pickering's Triangle." Approximately 8 hours of Ha and 8 hours of OIII with a Tak FSQ-106ED scope and QSI683 camera.
First attempt at processing this and I'm not entirely happy with it so I'd appreciate constructive criticism as always...
