Revision A is 2hr 40min of 1200s subs
Revision B is now at 10 hrs or so, moved up to 2400s exposures and add CLS filter to try and bring out the outer shell, tough battle
Revision E is now with 4 hours of Oiii with an Astronomiks 12nm Oiii filter, it is painfully obvious I am a newb at mixing narrowband!
Revision G is whackadoodle over the top processing using only the HA and O3, 6hrs 40min HA and 11 hrs O3
