Description

This work started in 2013 and brings together data collected mainly with my ED127mm refractor, but also with Newton 200mm and some 70 and 80mm refractors that have had a trial in recent years.

The image is a composition of luminances and filtered images also in narrow band. Note the four really weak lobes in OIII, part of a larger annular structure. They are not artifacts.

The overall exposure amounts to approximately 50 hours.
