Description

Reworking of a photo taken in 2016, with new techniques. It is 20 hours made with Halpha, OIII filters and a 685nm Ir-Pass filter, from the polluted sky of my home. Fortunately, the narrow band filters help a lot to increase the contrast from the sky background. The low sensitivity of my camera forced me to do more than 20 hours of exposure, in 7 nights
