Keystoning for High Angle Tracks

In addition to working out the details of making picokeystones for the interstellar candidates, I’ve been working out a method of extracting the high angle “off-normal” tracks in the interstellar collector. Since the collector must remain fastened to the microscope stage, it cannot be rotated in order to align the […]

More Picokeystone Improvements

Since our trip to JSC, we’ve been fine-tuning the procedure for the extraction of interstellar candidates. Today I’m testing some new “axial” code that Andrew wrote in order to compensate for slight deviations in the vertical needle’s alignment. In this new procedure, we measure the angle that the needle makes […]
