Image Description and Details: The Object: Even though the pictured area has no single catchy name, a lot is happening here. The ambient, ionized oxygen nebula (the overall blue) is being hit by strong stellar winds from the star in the center which is well known as Wolf Rayer WR 134, a very hot and massive star - supernova candidate . The blue, glowing Arc (or Bubble) has been created by this hot wind hitting the nebula. The red indicates the Hydrogen regions called LBN 182. Upper right is a Dark nebula Bernard 147
The making of: The area is not very bright so the collected 18 hours is barely enough to process with some challenges included. I started late in the the year imaging only after it was transiting meridian. It's 47 x 600s in Hydrogen, 61 x 600s Oxygen. Oxygen signal is very faint as compared to Ha, so both were processed quite differently before dynamically merging into HOO . RGB stars added through 60x30s subs total.
The idea was to depict the two layers: oxygen on top, hydrogen more in the background, still both wrestling one with another. My first use of a 4.5nm and 3nm Antlie filters. Shifting from ZWO 7nm made be double the subs duration time. Surpringly, it was more resillient to guiding's random issues. Looking at the more oval stars in the corner, it should make me motivated to finally eliminate the tilt.

Equipment Details: Mount NEQ6 PRO, William Optics GT81 w/flattener, Camera ASI 1600MM Pro, Guided with ASI 120MM
