Remove scaling of selected pixel #152

Previously the Bright Star Alignment pulled its own centroids using the standard Tetra3 system. To make this very consistent and speed things up, a 1/2 resolution image was used.

Now that the BSA is using the matched_centroids info from the latest solve, this scaling is not needed and was causing the selected pixel position to be doubled.

TODO: Using the matched_centroids is very stable (no flicker between similarly bright stars) but means you can't align on a planet.... We might want to change this or update the docs.
