Description

Sh2-290 Planetary Nebula in Gemini.  Distance about 2000 ly and diameter about 29 ly.  Actually this PN extends to the south so is larger than the 15 arc minute catalogue value.
H-alpha red, Sulphur II yellow, Oxygen III teal.  This object that resembles the Helix is tiny with my wide-field telescope but well worth the effort.
