CG4 Nebula – The Glowing Hand of God
The image was remotely captured from the Chilean desert, one of the areas with the lowest light pollution on the planet, making it ideal for astrophotography. The subject is the evocative CG4 nebula, nicknamed "The Glowing Hand of God" due to its elongated, ghostly shape resembling an outstretched arm reaching toward the small galaxy PGC 21338. This structure lies immersed in a vast field of ionized hydrogen filaments and dust, which in perspective overlap with the irregular galaxy NGC 2427—though in reality, the latter is located at a much greater distance.
📋 Technical details:
Newton ASAN 250 (250/950mm), Paramount MyT mount, ZWO ASI 6200 MM camera, Chroma filters (Luminance, Red, Green, Blue, H-Alpha 3nm).
Exposures: 23x300s + 228x12s (Luminance), 6x300s per RGB channel, 21x300s Ha all bin 2x2.
