Eta Carinae Nebula (Carina Nebula) imaged with a 4 in refractor at 565 mm focal length, an ASI 533MC cooled astronomy camera, dual band H-alpha and O-III filter, with an ASI 174MM guide camera. This target is particularly difficult to image since it is very low in my local horizon, only about 15 degrees elevation. It is relatively bright and easy to find due to the presence of nearby bright stars. Due to its low elevation, however, this target needs very clear skies.
