Strange bedfellows indeed.
This pair of objects are linked by clouds of Ha, but appear as wildly differing shapes.
Two panel mosaic with the bottom data captured almost exactly a year ago and the top captured last night under (and almost next to) a full moon resulting in another trip to gradient city.
Average seeing & some thin cloud meant the two data sets are a challenge to process as one.
I plan to eventually add RGB to this but not until under a dark sky again!
Tempted to add another panel or two to the right to include the infamous WOLF'S HEAD nebula.
Approx 6 hrs per panel, 30min subs.
Captured from suburban Melbourne.
