I've acquired around 50% of the data for this mosaic. I'm not getting into a hurry as I hope to present a rich and smooth representation of this ancient supernova remnant. I plan to shoot 6 panels and capture the entire Cygnus Loop. I'm really liking the color I've managed to capture over the last few months. This is a span of two panels to complete the structure in Cygnus.

Image statistics:
L- 20 x 180s
R- 20 x 180s
G- 20 x 180s
B- 20 x 180s
HA- 20 x 600s
O3- 20 x 600s

Making it around 10.5 hours per panel at present. Image acquired during July and August in Marathon Texas.
