The Jellyfish Nebula Region

This “widefield” image shows a view as wide as 10 full moons covering parts of Gemini and Orion. It shows a variety of objects, the Jellyfish Nebula and its fainter neighbor SH2-249, the bright emission and reflection nebula-Monkey head (NGC2174); and the familiar M35 star cluster at lower right. The hydrogen-alpha subs were taken from my place in Taguig City and the color subs were from Antipolo. I used “lighten mode” to initially combine the h-alpha with color but the numerous stars overwhelmed the field, so I blended the “red channel” of the color to the h-alpha and recombine with the composite color then used the HaR as luminance. I experimented in using the Canon 200 lens at brutally full F2.8 for both h-alpha and color!
