NGC 7635 – The Bubble Nebula
Description:
Catalogued under NGC 7635, the Bubble Nebula is really special. With a diameter of 10 light years and 11,000 light years away from us, it is a mass of ionized hydrogen blown by the stellar wind of a young star (the brightest in this photo). I took this photo with several different filters over 6 nights to bring out its structure.
Technical details:
Telescope: Celestron Edge HD14 with 0.7x focal reducer
Camera: ZWO ASI 2600MM in bin 2×2 mode
Filters Chroma RGB filters and Optolong narrowband filters
Exposure: A total of 11 hours with 10-minute subs in narrowband
PixInsight processing with Sulphur II assigned to red, H-Alpha assigned to green, and Oxygen III assigned to blue. RGB data was used for the stars.
