There are a couple ways to image this either focusing on the natural colors of this region or blending in the faint red glow from the hydrogen gas collected with a narrowband filter. I did the hydrogen blend method because I not only like the look but also narrowband filters handle light-polluted skies much better. I really like how the dark Boogeyman pops out against the deep red glow of the background hydrogen.
This is most likely my last Nebula Image taken from the Happy Frog Observatory. I would have liked more data but the weather has been unusually cold and snowy. However, I am doing one more image but it was a last minute decision and it's a galaxy. As luck would have it, the camera (ASI 1600) developed a splotch on the sensor for the first time and needed to be cleaned.

Absolutely stunning capture of LDN 1622, the Boogeyman Nebula! I love how you brought out the contrast between the dark dust lanes and the faint glowing background — this complex region in Orion really rewards long exposures and careful processing. It’s also inspiring to see how modern equipment like ZWO cameras and filters help bring out such subtle details in elusive dark nebulae that are otherwise invisible to the eye. Thanks for sharing both the image and the acquisition details — posts like this are truly motivating for astrophotographers chasing challenging targets!
