This is a first for me in that the entire data set for this image has been captured using the iTelescope remote facilities at Siding Springs, Connabaraban in NSW, Australia. The image data was captured over several nights in June 2020. The calibrated data was downloaded and then processed entirely in Pixinsight.

Capture data:
Red = 20 x 300s
Green = 21 x 300s
Blue = 18 x 300s
