Messier 77 Hubble Space Telescope
Well, this was my hardest job until now. Combining the different datasets to get equal colors was really hard. M77 was not fully covered by one dataset, so I had to combine channels of the WFPC2 with different wavelengths and tune the colors to get them to fit. But the result is in my opinion quite astonishing. Unbelievable this one was not released before....
Datasets used (a lot :) ):
