Description

Two panel mosaic of M42 in Narrowband. This was the last image I took with my ZWO filters prior to moving to Astrodons. I actually have a third panel, but my computer would not process the image and would crash Pixinsight when doing the MosaicMerge. I used HDR with both 10s and 240s frames on each filter to try and capture as much detail as I could. This was 6.2 hours per panel.
