NGC 6872 the Condor Galaxy and others.

Taken under Bortle 6 to 7 skies, almost amazed its possible to pull any detail from galaxy clusters under such bright skies, and filters of no use with galaxy imaging.

I saw this interesting galaxy cluster on DSS images so thought Id have a crack at it. Loving the EOS Ra, with ISO at max test shots of just a few secs reach well into the sky background, making composing images easier, the galaxies were visible, and the live view makes focusing spot on.

The battle really begins once I have the data, dealing with strong light pollution that turns into a strong gradient as I process the calibrated, stacked image. It plays havoc with the colour balance trying to get the sky looking neutral. Anyway here it is, I cropped just the interesting part, there are smaller fainter galaxies scattered throughout the full frame. A full frame camera seems so big compared to the old 350D.
Full res version of the cropped image below. Hand guided as usual.

Very nice, I struggle with some galaxies only because my guiding star are not strong enough for my webcam.
