Sh2-101 – The Tulip Nebula

With the end of summer twilight and the return of dark nights this is my first target of the season. The Tulip Nebula is often imaged in narrowband and with a wide field the surrounding area is full of Ha. There are also some OIII filaments.

This image is comprised of RGB frames (1/1/2 hours) combined with 2 hours of Ha and 9 hours of OIII. All subframes are 20 minutes.

Combination is using the Pixinsight EmissionLineIntegration script.
