The weather stopped me from getting equal integration times for each panel of this 4 panel mosaic, but I am quite happy how it turned out.

Most of the data collected was for the bottom right panel (p2) for which I have also got OIII and SII data (image to follow).

The panels are numbered as follows:

p3 | p1
p4 | p2

p1: 18 x 600s bin 2x2
p2: 12 x 1800s bin 1x1 & 8 x 600s bin 2x2
p3: 17 x 600s bin 2x2
p4: 14 x 600s bin 2x2

Imaged over 17 nights from Nov 2017 to Mar 2018
