Description

Extremely thankful to my collaborator and mentor, Mike Selby for this amazing opportunity to process this incredible data from a location I have no direct access to! The Large Magellanic Cloud  is way too deep south for my latitude! This image really helped me understand this region with all of the different regions coming together in this huge field!

Please look at this image in full resolution mode and explore at the enormous field of  view in detail!

The Large Magellanic Cloud is a satellite galaxy of the Milky Way located around 163,000 light years away., it is massive in the field of view covering an area of 462 x 516 arc minutes. In order to capture the entire galaxy, this image is made up of 12 separate image panels forming a mosaic of the galaxy. It consists of a total of nearly 150 hours of exposure time and in full resolution is 300 megapixels with a file size of around 1.3 gb.

Imaged in LRGB and H alpha on Mike Selby's  Planewave DR 350 at Observatorio El Sauce, Chile.

Data and preprocessing by Mike Selby

Processed by me using Pixinsight and Photoshop.

This image for its sheer scale was a challenge to process! I have a desktop with 128GB memory and NVIDIA and CUDA and this data pushed it to the limits! My working xisf and tiff's are each over 1GB! I tried very hard to focus on the main cloud as well as the nebulae that are present all over, and tried to do justice to all of it and keep the stars under control!
I processed the RGB using SPCC, BXT and DBE and careful stretching. Blended in Ha to bring out the nebulosity.
Lum is extracted from RGB and a light touch of Ha in some areas.

Size of the jpeg here is 240MB and loaded in Astrobin! I am figuring out how to share a 1.3GB tiff for a better in depth drill down of the details.
