This Jellyfish data was acquired at the same time as my last Jellyfish nebula picture in the Hubble pallet. This was captured with my ZWO ASI533MC Pro with the Optolong L-Enhance filter on my 11" RASA. Although captured with a One Shot color camera, I consider this narrowband as this filter is Ha/SII. I also captured some of this data under close to a full moon which is impressive.
