I invested 4 nights in this image – but I got a very deep image.

With a moon on the eighth day (Quarter) we can see one of the most impressive formations of the moon are the Apennine Mountains,
with peaks over 4500 meters above sea level and spanning more than 600 km.

Here is some more hubble imagery not processed this way before:

NGC 3314 Two overlapping galaxies
Full resolution: http://www.astro-photo.nl/photoblog/ind ... wimage=183
Copyright: Hubble Legacy team/NASA/ESA processing: André van der Hoeven For the color layer images from the WFPC2 detector were used (450, 555, 675 and 814 nm). For the luminance high resolution ACS detector images in two bandwidths (475 and 606 nm) were used. This results in a high resolution image with better color information than the original image from the hubble team from 2005.


NGC 1376 A spiral galaxy from above
Full resolution: http://www.astro-photo.nl/photoblog/ind ... wimage=182
Copyright: Hubble Legacy team/NASA/ESA processing: André van der Hoeven In this overhead image of NGC 1376 in total 8 bands of hubble imagery were used to obtain the color and detail. This results in a highresolution image of this beautiful galaxy...

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.... This is what I call a hidden treasure...

Datasets used (a lot ):
hst_05754_01_wfpc2_f336w_wf
hst_05754_01_wfpc2_f502n_wf
hst_05754_01_wfpc2_f547m_wf
hst_05754_01_wfpc2_f658n_wf
hst_05754_01_wfpc2_f791w_wf
hst_05942_01_wfpc2_f673n_wf
HST_9788_02_ACS_WFC_F658N
