Globular Cluster NGC 6652

A challenge for the determined enthusiast.
Please note, that these images are not aligned, and one also need to be rotated before the three exposures correspond to each other. This is definitely not the data set you should take, if this is your first try at astronomical image processing!

555wmos.zip: A zip'ped FITS file taken with the NASA/ESA Hubble Space Telescope WFPC2 camera of the planetary nebula NGC6881 through a wide-band 555nm filter (V band). 6.5 MB
814wmos.zip: A zip'ped FITS file taken with the NASA/ESA Hubble Space Telescope WFPC2 camera of the planetary nebula NGC6881 through a wide-band 814 nm filter (I band). 9.3 MB
ngc6652_composite.zip: A zip'ped Photoshop 16 bit (.psd) example file that contains a full three-colour image of the datasets taken with the NASA/ESA Hubble Space Telescope of the planetary nebula NGC6881, imported into Photoshop with the ESA/ESO/NASA Photoshop FITS Liberator, 32.3 MB. These images are not aligned or rotated - or well balanced :-)
