Astrofotografie
One of my favorite things to image, the cosmos.
There are lots more of images on the
Messier Catalog page.
Image Processing
- the GIMP - General purpose good for every kind of images.
- UFRaw - for nicely importing those pesky RAW files to the gimp.
- lxnstack - automates aligning and stacking of hundreds of images.
- DS9 - CCD processing and analysis.
