AstroBuffer is a CCD astrophotography image manipulation application.

• Opens FITS and SBIG (st9) files
• Adjustable contrast to view different background and range of a image.
• Scale
• Shift
• Rotate
• Align Images based on two star alignment
• Sum images
• Zoom in and out
• Magnification window
• Subtract images
• Average images
• Apply Convolutions
• Take pixels to x power
• Divide (flat) images
• Lesser two images
• Center object
• Copy/Paste Selected
• Resize Canvas
• DDP
• Software Binning
• Create L/RGB color images from four/three images.
• Decompose saved L/RGB color images into separate images.
• Create new Images with specified value.
• Save as a image that KDE supports
• Save as FITS

Below are the requirements that need to be installed before running this software. Not listed are the requirements that each of those need.

There is much to do, more than listed here, but here are some of the first things planned to be worked on.

• L/CMY support
• Make various dialogs more easier to use (Example: Scale should allow you to put in dimensions)
• More provided Convolutions
• Better Cosmic Ray removing options
• More flexable background-contrast settings
• Support NASA PDS images
• Mosaic
• Star bloom Removal
• Improve Speed (Look into using more of SciPy)
• Cleanup code (It is sorta a mess right now)
• Write documentations include tutorials and some example images to play with.
• Make a icon for the application
• Make centroid work better (Used with alignment)
• Fix endian issues (I’m sure it won’t work on big endian)
• Fix type/large value issues (histogram slider breaks if you have very large values, no reason to have 64 bit float the default, divide is messed up)
• Fix up settings menu
• Better Copy/Paste tool
• An option to use other interpolation methods (cubic, spline?)

• Cross Cursor in viewport widget
• Bugfixes missed while porting to PyQt4

• Update pyfits version to 1.3
• Application icon
• Move to PyQt4, PyQwt5, and removed PyKDE
• PySBIG is optional
• Software Binning
• Settings Dialog to set image precision added
• Added File→Open Recent
• Rearrange menu items

• DDP
• Fixed some image size checks
• Fixed wrong url reference for document copy()
• Resize document starts with documents size in options
• Scale dialog has size spin boxes
• Quadratic Sum Tool
• Fixed menu bug when color document opened after non color document
• Multiply Tool added
• Laplacian of Gaussian Convolution added

• Copy and Paste with selection added
• Doesn’t crash on File→Quit anymore
• Resize Canvas Tool
• Fixed mean value in 60% divide (flat)

• inline C version of centroid to improve speed
• Fixed memory leak caused from undo system
• Works with numpy 1.0.2 and scipy 0.5.x

• Make Center tool for centering an object
• Autocontrast works better
• Can right click on tab for a popup menu
• Workaround for RGB name increment problem

• Fixes reading background range from previously saved rgb and lrgb files.

• Changed auto contrast so it wouldn’t prevent loading flat files.

• Rotate, Scale, Shift dialogs go back to default settings after apply.
• Convolution dialog to do convolutions with with Guassian, Zeros, and Custom kernels
• Duplicate option
• Power Tool (i.e. each pixel x^y value)
• Can rename tabs
• Changed Contrast Dialogs

• Error message box gets shown if exception occurs
• Uses scipy histogram to improve speed
• Fixed getHistograms for color images so green and blue are in correct order
• Reorganized the ColorRGB?Document code
• Undo/Redo

• Added L/RGB capabilities instead of just RGB.
• Decompose created L/RGB images into separate images
• Able to create a new image with all pixels a specified value
• While opening a FITS image, it checks to see if HDU is primary or image HDU before trying to open
