Today I implemented most of the algorithms I pointed out in my last post and found that they worked pretty well... - ...with focused stars. If they are let loose on an image with out of focus stars some of them will need a bit of tweaking. Things like the centroid finder and HFD computation seem to work ok regardless, but the algorithm to actually find stars doesn't work properly when they are out of focus. This is because it checks the pixels around the star to make sure they roughly follow a nice looking Point Spread Function. But of course, when the stars are out of focus, they don't look like that at all. So it is back to the drawing board for that one.
