Description

This is a 3 panel mosaic in SHO palette (total of 9 panels, 20% overlap).
It turned to be extremely challenging due to the strong aberration of each panel as the 0.72x reducer/corrector didn't come with an acceptable flat field.
The Sadr region is one of the most fascinating areas of the northern summer sky and this particular framing has been carefully planned to also include the Crescent Nebula.
In this composition, the Crescent Nebula has been processed using a variant of the HOO palette. This image has been rescaled to 75% from its original size of 15000x3729
