Description

In this picture I tried to show as much of nebulosity as possible to bring out the planetary nebula KjPn8 and at the same time to control the dynamic range inside the bubble without loosing the blues on the upper part of the bubble.
The Hydrogen alpha master was composed as HDR of subframes of 600 and 300  seconds.
Data obtatained from the 2nd to the 14th october 2023
