I imaged 4 panels of this Deep Space Object (DSO) and stitched them together using PhotometricMosaic script by John Murphy. Each panel contains data of nearly 3 hours of exposure in Dual Narrowband filter (HOIII). Luckily there were 2 cloud free nights just before new moon to image this target. Hope to build on this data in the near future and see some signal improvements.
