Description

Imaging from highly light-polluted skies is always a challenge.

RGB imaging is nearly impossible, narrow band imaging cannot reproduce "true" colors of objects...

... or not?

With the right technique one can get narrowband data from selected objects (emission nebulae) and recover star colors from broad band RGB images.

This image comes from the composition of 6 filters: RGB for star colors, H alpha, OIII and H beta for the nebula.

Unfortunately, due to the high Light Pollution, it was impossible to get better data for the dimmer object, but i'm quite happy of the result under a 18.5 mag/arcsec SQM sky
