Seen here is a populary imaged deep sky object: The Tadpole Nebula. In professional astronomy, it is also known as IC 410. This is a faint and dusty emission nebula of more than 100 light-years across, located near the Flaming Star Nebula (IC 405) in a large star forming (HII) region about 12,000 light-years away from Earth in the northern constellation of Auriga.

​

The cloud of glowing gas is sculpted by stellar winds and radiation from the embedded open star cluster catalogued as NGC 1893, which is just about 4 million years old. The massive, hot stars of this cluster are all very young, having only been recently formed from IC 410. The bright stars of this cluster are seen just below the prominent dark dust cloud near picture center. There are two gaseous streams in the centre of the image which is the “Tadpoles". These tadpoles, which consist of denser, cooler gas and dust, are approximately 10 light-years long and potentially sites of ongoing star formation.

​

I took a different approach in processing this target, mainly because of a sudden change of plans, I had to cut my imaging project short (therefore, there is no Oxygen III data this time). I was about to ditch the entire project until i recalled seeing some deep space targets that were processed in the H-S-S palette. Thankfully, I'm glad that the data collected was still useable and not too shabby, although the Sulfur II data could do with more data.

 

Nevertheless, I hope this personal recount gives you some insight into (not just me) the mental dilemma that most photographers will face when their project goals are not met due to unforeseen circumstances! Hope you enjoy this image. A higher resolution image can be found here: https://flic.kr/p/2obtjEN
