Flaming Star Nebula and Friends

Finally got a complete HaRGB image of the Flaming Star Nebula and friends last Saturday night. It was not clear at first but by 11 pm it was pretty clear (and cold) so I managed to get a couple hours. I did not use a filter to capture the RGB data as I wanted to keep some of the colorful star field that I have seen others capture. Also, I used a 0.8 focal reducer with my f/7.5 ED80 in order to get IC 410 although a an f/5 80mm or less scope would have given a better FOV.

The Flaming Star Nebula (IC 405) is composed of red and blue colors created by different processes. The bright star AE Aurigae is so hot it is blue, emitting light so energetic it knocks electrons away from surrounding gas. The two regions are referred to as emission nebula and reflection nebula, respectively. The Flaming Star Nebula, officially known as IC 405, lies about 1500 light years distant and spans about 5 light years. Close by is another nebula, IC 410, surrounding the open star cluster NGC 1893 (source: skyfactory).
