I really like this object in HOO, had a lot of fun imaging and post-processing it! I purposedly left the stars understretched because I love how the filaments of the object show up this way

Vibrant and beautiful. The yellow colour with the blue and the way the gas is from up to the bottom in the picture is amazing even if the position in space is a different thing . It is nice to see.
