All Galaxy Photography prints are ready for framing. I suggest you choose a good framing shop familiar with photographs.
Most prints look best when double matted with a black frame.
The outer mat should be a dark grey or black. The inner mat should match the color of the object, for example use red for a nebula photo, blue for a galaxy. 16x20 prints can be matted such that they fit in a 20x24 frame. I have seen many photos framed by my customers as described above and the color keyed mats really bring out the beauty of the object. The snap-shot of it below does not begin to do it justice, but it gives you an idea about how you may want to frame your print.
