Description

RCW 98 - The Coffee Bean Nebula, in Norma, is a ring nebula with a central Wolf Rayet star.

It was captured with SGP on May 2020 using a 5 nm Ha filter (22,5 hrs), a 3 nm OIII filter ( 20 hrs) with a 4" scope plus a QSI660 camera, and processed on June 2021 using Pixinsigth software, all from Lat -33, Long -70, Santiago, Chile.

The contribution of OIII is almost nothing.

The nebula to the right is RCW 97, part of this giant HII region.
