    Description

    The Seagull Nebula is my "cross-decade" project. 😃

    To me, this target is hard - it's right above mega Dallas downtown light pollution dome and travel low on top of the neighbors' roof. The data came back really broke my heart. Half frame of the the O3 master is bright light pollution. Indeed, the challenge was managed well.

    Overall I love the final result, got the details under the wings I was expecting. I did a more "Traditional" color scheme with warm colors.

    Hope you guys like it! 👁
