Where it is in space

A faint, dusty rose of the northern sky, emission nebula IC 410 lies about 12,000 light-years away in the constellation of Auriga. It lies approx 5.4° west of the mag 2.7 star Iota Aurigae.
I

Acquisition

Remote session using RADMIN PC control from Ravenshead, UK.
Exposures:- 320:400:420 mins total using 20 min Ha, SII and OIII, 100 mins each for RGB using 5 min subs.

  What it is

The cloud of glowing hydrogen gas is over 100 light-years across, sculpted by stellar winds and radiation from the embedded open star cluster NGC 1893. Formed in the interstellar cloud only about 4 million years ago, bright cluster stars are seen just below the prominent foreground dark dust cloud near picture center. Notable near the 6 o'clock position in this wide, detailed view are two relatively dense streamers of material trailing away from the nebula's central regions. Potentially sites of ongoing star formation, these cosmic tadpole shapes are about 10 light-years long.



Processing Methods

Image acquisition and telescope control with CCDSoft V5. Remote acquisition sequence program CCDAutoPilot.  
  Data reduction, Synthetic Luminance (Ha+SII+OIII) de-convolution and master RGB colour image prepared with CCDStack.  
 

Narrowband combination and blending created and finished with Photoshop CS6. Final RGB image created using PhotoShop CS6.
