Description

I named this image "finally" as I've never been successful getting the Tads before.  I find this to be a tough target.  Wondering how you all find it to be?

This image is pure SHO with RGB stars.  I was able to resolve the dim stars in the top Tad. (go ahead and pixel peek.)  They don't show up in many pictures...kind of like the trapezium stars in Orion.  I dialed back the sharpening of BXT to almost zero, but I did use Bill Blanshan's star reduction methodology.  Interesting that I found straight Pixmath SHO_starless + RGB_stars to give the best result after trying Bill Blanshan's RGB to NB modes 1 to 5.   I found this difficult process and spent much time on the Ha which I used as luminance.  

A few hours of Ha from backyard, but most data is from 2 nights in Death Valley where the clouds are less...but was windy.   It's raining again on this new moon here in sunny California.  last year where I live we had 6.7" of rain total.  We are at 32.5" so far and more coming.  65' of snow at Mammoth Mt. 😀   -john


from NASA: Formed in the interstellar cloud a mere 4 million years ago, the intensely hot, bright cluster stars energize the glowing gas. Composed of denser cooler gas and dust, the tadpoles are around 10 light-years long and are likely sites of ongoing star formation. Sculpted by winds and radiation from the cluster stars, their heads are outlined by bright ridges of ionized gas while their tails trail away from the cluster's central region.   and from Sara Wager Astrophotographer: IC 410 is a faint and dusty emission nebula of more than 100 light-years across approximately 12,000 light-years away from Earth in the northern constellation of Auriga. Notable are two streamers of material, known as the “Tadpoles of IC 410”. These tadpoles, which consist of denser, cooler gas and dust, are approximately 10 light-years long and potentially sites of ongoing star formation. They are almost in the centre of the image. Form given by the winds and radiation of the cluster’s stars, the tadpoles are pointing their tails outwards, away from the nebula’s central regions. Because of these tadpoles, IC 410 is sometimes nicknamed the Tadpoles Nebula.
