Description

Tried to use Nikon 300mm with TC1.4III to shoot M81/M82 pair one time. But the distance is too much for 420mm. So here comes the Hubble version! The data could be found at MAST (https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html).

Target: NGC 3034 (M82)

Went back to Fits Liberator and Photoshop one more time. Somehow the auto-stretch results from different images are not normalized as expected. Converted FITS files to TIFF with Fits Liberator and manually leveled all images in Photoshop before HaRGB process started. Cosmetic touch-ups done in Photoshop. Final process completed in Lightroom.

ACS/WFC: F435W

ACS/WFC: F555W

ACS/WFC: F658N

ACS/WFC: F814W

Color Mapping (PixelMath):

Red - F814W, F658N

Green - F555W

Blue - F435W

The original data images are mosaics of multiple Hubble shots with each filter. The result of the mosaic is not very good. Took quite some time to heal the exposure gaps.
