Sombrero is a fast wavelet image processing and object detection C library for astronomical images. Sombrero is named after the "Mexican Hat" shape of the wavelet masks used in image convolution and is released under the GNU LGPL library.

PGMania is a universal package for processing deep space images. The program provides wide and unique functionality, a powerful and flexible tool with a clear and user-friendly interface. The program performs all image processing cycles for astrophotography, including filtering, cleaning, aligning, image calibrating, stacking, post-processing, format conversion, cropping, rotations, many special operations and much more. PGMania is environmentally friendly - it does not clutter your photos...

...The features of latest version are: * Several stacking methods (average, median, sigma-clipping, ...) * Two automatic align method: align-points; phase correlation, * One manual align method. * sub-pixel precision (0.1 pixel for phase correlation and 0.01 pixel for manual alignment). * Automatic image derotation. * FITS file support (by installing the python2 package 'astropy') * Hot pixels suppression algorithm * CR2 files native support * Can load/save video * Grayscale RAW image support * Editing of result image's levels...

...This allows free rotation of the sphere, avoiding the distortions of Aitoff and other projections often used. It is a very practical way to view and prepare skymap plots of GALPROP output. GALPROP outputs a spectrum per HealPix pixel, while Aladin requires each energy to be stored as a column. A conversion is required to make GALPROP skymaps viewable in Aladin. This program performs this conversion, outputs both the original energy bins and energy-integrated spectra, and in addition convolves with a user-defined Gaussian both in energy bins and energy-integrated. ...
