IC 417, commonly called the "Spider Nebula", is an emission (H II) nebula in the constellation Auriga. IC 417 is part of the Aur OB2 star-forming complex on the near side of the Perseus Arm and hosts many young stellar object candidates. IC 417 is roughly 6,700–7,500 light-years away.
This LRGB+HA image was captured in a Queen Creek (Arizona) Bortle 7/8 backyard using a Skywatcher Esprit 150ED telescope. The telescope is mounted on a 10Micron GM2000 HPS II mount. The camera is a ZWO ASI 2600MM Pro using Antlia VPRO LRGB and HA 3nm filters. It was captured over 19 nights (2026-03-10 to 2026-04-15). The images were captured using NINA and stacked/processed in Pixinsight.
