ESA\Hubble Legacy Archive database - M82

[Chris P.]

Hi everyone - I've been delving into the Hubble Legacy Archive for some raw data on M82. Processed in Pixinsight and Photoshop as a HaRGB (as best I can tell with the filter wavelengths used). Just a bit of fun 😉

 

Acknowledgment - Based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA).

Wow! You have done a nice job of it.

Wow indeed.

I once tried to access it but didn't get anywhere. Do you have any advice, please?

Hi Philip - HLA is not the most user friendly site. Definitely written for the science community. Best tip i can offer is ignore the inventory and use the images tab to pick the files you want and use the widefield camera images denoted by WPC***. If you do a search for an object the search engine will return all the catalogued images for that target. Some are next to useless but others have been combined for an RGB image. All I do is look for 3 grayscale images at different wavelengths (as denoted by the naming convention eg if includes a number in the 400's it's at the blue end of the spectrum; 650's is at the red end etc) and see if I can align them in Pixinsght. The M82 image was mosaic'd because you can see the joins - but you can process that out. Hope that helps
