Sample frames taken using this estimate

Re-evaluate after finding max pixel count for sample frames in python (to get pixel max in range 55000 - 60000)

1.1s for focus filter

5.1s for green filter

3.3s for red filter

10s for blue filter

1s for no filter

10 repeat dark

10 repeats bias - no exposure time

5 repeat red, green, blue, focus, no filter

Dark frames have residual image leftover from prior frames.

Add in dark capture before true dark frame (suffix = Trash) to clear excess charge.

Didn't work - small pixel count - continued taking data
