Thanks to Dylan for his
useful tool that I used to discover the best combination of filter data for this image!
This is around 13 hours of data I was able to grab back in December last year with the ASI1600 mono-cooled and Tak E-130D, as usual I would have preferred to get more data, but the weather was iffy back then, though it was the start of the great summer spell we eventually had. Max number of frames useable was 22 for Ha, all subs 900 secs, except for an hour worth of 60 second subs for the core.
I was sure I also obtained some RGB data, but alas I couldn't find it, so here I did my best to achieve a pleasing varied RGB look, well I tried at least!
