Ultraviolet Venus

218wmos.zip A zip'ped FITS file taken with the NASA/ESA Hubble Space Telescope WFPC2 camera of Venus through a wide-band 218 nm filter (Ultraviolet). 6.7 MB.
255wmos.zip: A zip'ped FITS file taken with the NASA/ESA Hubble Space Telescope WFPC2 camera of Venus through a wide-band 255 nm filter (Ultraviolet). 6.7 MB

venus_composite.zip A zip'ped Photoshop 16 bit (.psd) example file that contains a full three-colour image of the data sets taken with the NASA/ESA Hubble Space Telescope WFPC2 camera of Venus, imported into Photoshop with the help of the ESA/ESO/NASA FITS Liberator.
The green layer is constructed as an average of the two exposures. The image has been cropped, just to reduce the file size. 6.9 MB.

venus_composite_8bit.zip A zip'ped Photoshop 8 bit (.psd) example file that contains a full three-colour image of the data sets taken with the NASA/ESA Hubble Space Telescope of Venus, imported into Photoshop with the help of the ESA/ESO/NASA FITS Liberator.
The green layer is constructed as an average of the two exposures. The image has been cropped, just to reduce the file size. 2.4 MB.

Beware that the two ultraviolet images are almost but not totally aligned. Before doing the image processing it is strongly advised that you move one image to align it with the other (activate the layer it is in, and simply use the arrow buttons). Do it while the image is seen in a large magnification, to be able to do it reasonable precise.
