Description

Taking images from a city sky with an average SQM of 18.8 is always a challenge, even with the brighter objects.

This is an RGB Ha OIII composition taken under the light-polluted sky near Brescia in Northern Italy.

The nebula is A full narrow-band bicolour composition (Halpha-OIII) with a pretty strong deconvolution.
The stars and the galaxy IC1296 come from the RGB image.

IMO this is the maximum that I can reach with my current setup under this sky.
