10 Panel mosaic of Orion shot remotely from my system in Marathon Remote Imaging Observatory (MaRIO) in Marathon, TX.
I was blown away by the amount of dust in this area. This camera is amazing at picking all of it up. Of course with such a large sensor, the bright stars made things interesting. I had to adjust the positioning of the panels while shooting several time to keep flaring down.

Software used to capture image:
Sequence Generator Pro

Software used to edit:
Astro Pixel Processor

Each panel is slightly different on amount of subs. I shot 32 per panel but after culling some, the numbers are different.
Total data gathered:
Main Panel: (269) Subs @ 300secs - 1x1 @ Gain 2200

Camera : QHYCCD QHY128C
Telescope: Stellarvue SVQ86
Mount: AP Mach1GTO
