alan4908 Posted March 16, 2022 Share Posted March 16, 2022 IC 417 (aka spider nebula) is located in the constellation of Auriga about 10k light years away. It’s an emission nebula that is energised by hot blue stars. The image below shows the head of the spider. To enhance details, I blended in some Ha in the red and lum channels. To avoid a red colour dominance I also significantly boosted the blue channel. This highlighted some details, in particular, the ghoul at the bottom of the spiders head. The image below represents about 21 hours integration time and was taken with my Esprit 150. Alan LIGHTS: L:36, R:18, G:12,B:16 x 600s; Ha: 14 x 1800s. 10 Link to comment Share on other sites More sharing options...

Thanks for the comment - it was a bit of a challenge with the colour channels, so I thought of a bit of experimentation was in order. 1 Link to comment Share on other sites More sharing options...
