IC417 Spider Nebula


Recommended Posts


Here's IC417.  I can't quite figure out why its called the Spider Nebula (don't really see it myself).  16.5hrs of data - about 7h w double-stacked UHC & CLS CCD filters, another c 7h w 6nm HA, and c 3 hrs of luminance.  All done with an ASI294MCPro (I know, an OSC camera!).  I actually quite enjoyed the process - it's made me think about mono much more.

JPG'd for size, the closer crop is star-reduced to try and let the nebulosity show a bit more.  So many stars in that part of the sky!
