Got my best ever pic of RCW 103 last night. 6x10 mins ISO400, Hutech LPS filter, Baader MPCC, 10 inch f5.6 Newtonian. The full res crop shows some detail in the nebula
Unlike the Veil and Vela SNRs there is no green oxygen glow at all. The progenitor star , or whats left of it is thought to be roughly in the middle of the bright and faint nebulas. It was at the meridian when I finshed the run so nice and high.
