Originally I started recording with Orion Fall as the theme, but I can not ignore it because the Lost Jewel Of Orion Cluster on the right of the photo is shining beautifully, and I got cheating and the width of the planned angle of view is 5 It has become a premium.
The power of Orion Falls has diminished by that amount, but this is not bad for humans.
The nebula mainly merges Broad Band with Narrwo Band as the main.
The stars are mainly Broad Band.
I don't use HDR in the shooting technique.
6 hours longer exposure time as planned.
