In order to print 8x10s at 250dpi, I have enlarged ST6 images as much as
10x. Doing that with Photoshop's bicubic interpolation doesn't introduce
any obvious artifacts, and you don't see anything like pixelation. What
you end up with is a very nice looking print. Of course, stars and edges
are soft- but that isn't an artifact, that simply reflects the original
resolution of the data.
