IC 2169 also know as Dreyer's Nebula, is a faint reflection nebula in the constellation Monoceros (Unicorn).
Other well-known objects near IC 2169 include NGC 2237 (the Rosette Nebula), IC 443 (the Jellyfish Nebula), and NGC 2264 (the Cone Nebula).
I did the stacking in Astro Pixel Processor and the processing in PixInsight (Gradient Correction, SPCC, Super Luminance, BlurXT, ColorSaturation, HDRMT, NoiseXT, CurvesTansformation Lab 'c' -> because I think it gives a nice touch to the stars :-)).
