Large Magellanic Cloud - RGB_Ha

Image Title: Large Magellanic Cloud - RGB_Ha

Date image was taken: October 21, 2023

Location: Bathurst, NSW Australia

Image Description and Details: This image of the Large Magellanic Cloud (LMC) has been captured with a monochrome full frame CMOS camera (ZWO ASI6200) and Canon EF200mm f2.8 lens. This combination gives a 10d x 7d field of view, ideal for capturing the LMC in a single field. The Canon lens has been stopped down to f5.6 to improve the off axis aberrations that can be apparent when running these lenses fully open. The continuum mapping technique was used to integrate the Ha signal into RGB master.

It became quite evident in post processing that there was a significant amount of signal surrounding the main body of the LMC. Research was completed to identify the nature of this signal and confirmed that the signal around the field of view is genuine and does in fact show extended spiral structures around the galaxy.
