Why that filter set?

Intriguing and provocative image, Bart. Stopped me in my tracks. Was there a particular reason why you chose that filter set? I'm scratching my head what astrophysics is coming out here. Never saw those concentric dust rings at your 10:00 halfway to the upper l edge. 2070 is too young for those to be SNRs. They're also too far out to be ejecta. Also those unresolved yellowish blobs 4:30 below r just exterior to the 2070 gas ejection bubble. Are those pixel saturation or real gas overdensities? Thanks, Dana in S Africa
