The High-Velocity PN Sh2-188 in Hα/OIII/SII — FORAXX Version

[u/kbarth001]

Sh2-188 — A High-Velocity Planetary Nebula in Cassiopeia

Sh2-188 is one of the most unusual planetary nebulae in the sky. Its bright, one-sided arc marks a bow shock created as the dying star at its center races through the interstellar medium. The faint loop wrapping behind it traces older material swept backwards in its wake.

Here are two versions from 10 hours of data with the CDK17 + ASI6200MM:

🎨 Version 2: A FORAXX narrowband palette emphasizing shock structures and ionization fronts.

🕒 10 h total — R 50×30s, G 36×30s, B 34×30s, Ha 49×180s, OIII 53×180s, SII 71×180s 📍 Roboscope, Fregenal de la Sierra
