NGC55 - The Whale Galaxy (Astrobin IOTD 28 Jan)

NGC55 is a barred spiral galaxy located in the constellation of Sculptor about 6.5 million light years from Earth. I've always found this galaxy to be an enigmatic object given that at first glance it is not visually attractive in any way like its neighbor NGC300 (others may disagree and please feel free to do so!). It does however demand attention and every astro imager feels the need to have one in their portfolio of images. I admit that after spending time with this galaxy it kind of grows on you. It certainly has a unique shape resulting from the angle that the galaxy lies in our line of sight when looking from Earth.

Processing this image was particularly challenging because of the severe reflection artefacts that were present in the data collected. This required significant work to remove and added quite a few hours of processing time to the workflow. I think that I'm going to have to pull down my image train to try and locate the source of the reflections.

Link to image on Astrobin is here.

Clear skies,
Rodney
