Description

I think this is my longest integration thus far, just over the 20 hour mark.

Focus was on the "fighting dragons", but I think this wierd little Planetary? nebula (PK336-0.1 or NGC's 6164/5 and 5189) and it's surrounding shell kinda steals the show. I had no idea it was here till I started imaging and it is an intriguing little object.

That's why I turned this on it's side rather than have the dragons facing each other horizontally across the frame as is most common...didn't want to relegate my little PK friend down the bottom to be missed :-)

I was trying to get the back story on it (PK336-0.1) but not clear...think it's two events...the fine blue outer ring earlier than the "s" shaped central nebula.

Guess those dragons have quite a bit of interest as well ;-)

Taken over 4 nights with roughly equal parts Ha, OIII and SII.

Stacked into channels in APP and combined and processed in Startools with final tweaks in PS.
