I am now going below the -30º Declination line to reveal a couple of galaxies in the constellation of Antlia, the Air Pump. Imaged from the UK, NGC 3100 and 3095 are both below 12th magnitude in brightness and -31º30' in declination. As you can see, with the low altitude, the atmosphere has shaken the stars into big disks, after realigning the Red, Green and Blue channels as a matter of course. I also spent ages messing around with the background subtraction, as the raw images were a bright milky brown. 27 x 15" f/3, f~1.5m, ISO 1600.
