NGC7822

NGC 7822 - The Question Mark Nebula I attempted this target earlier in the year using the L-eNhance filter and once I got the L-eXtreme I wanted to give it another go. Captured over 3 nights at the end of imaging sessions, I was able to capture 4.5 hours and it blows my 3 hours with the L-eNhance away. Note, IG doesn't do this target justice, so head over to astrobin, link in Bio or below, to check it out full size. . Full resolution and details at Astrobin.

NGC 7822 - The Question Mark Nebula This nebula is found in the constellation Cepheus. This is another target inspired by @robert_leach90 that I was finally able to get started on. Because it's more North then East, this is currently a difficult target for me, and that doesn't include the clouds I had rolling in! I was able to get 3 hours and look forward to getting more soon. . Full resolution on Astrobin, link in Bio . 45 x 240s Dark, flat, bias and dark flats used for calibration.

Explanation: Hot, young stars and cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away. Within the nebula, bright edges and dark shapes stand out in this colorful skyscape. The image includes data from narrowband filters, mapping emission from atomic oxygen, hydrogen, and sulfur into blue, green, and red hues. The emission line and color combination has become well-known as the Hubble palette. The atomic emission is powered by energetic radiation from the central hot stars. Their powerful winds and radiation sculpt and erode the denser pillar shapes and clear out a characteristic cavity light-years across the center of the natal cloud. Stars could still be forming inside the pillars by gravitational collapse but as the pillars are eroded away, any forming stars will ultimately be cutoff from their reservoir of star stuff. This field of view spans over 40 light-years at the estimated distance of NGC 7822.
