PHOTOGRAPH #284 · nebulae
Iris Nebula — Instagram Study
Randal Healey · Utahopia Observatory
I have shot the Iris nebula many times but I keep trying to improve the result each time in terms of data and processing. I hope you enjoy this latest attempt.
The Iris Nebula is a reflection nebula approximately 6 light years across and 1,300 light years away from Earth in the Cepheus constellation. Within the nebula, dusty nebular material (i.e.; interstellar dust and gas) surrounds a massive, hot, young star in its formative years. Central filaments of cosmic dust glow with a reddish photo-luminescence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. The nebula's dominant color, blue, is the result of dust grains reflecting star light. Infrared observations indicate that this nebula may contain complex carbon molecules known as PAHs.
Thanks
