To recharge the desiccant, place the tablet in an electric oven at 200ºC

for a couple of hours. Take it from the oven, wait a few minutes for it to

cool down slightly, then put it back in the camera and wait 24 hours.

You will notice that there is a filter inside the desiccant chamber. The purpose

of this is to avoid contamination of the chamber when the desiccant is being

replaced. The filter is very fragile and should not be touched.

The following table gives the angular resolution per pixel with certain focal

distances. The formula to calculate any other focal length is:

(Pixel Size (μm) / Focal Distance (mm)) * 206.3 = angular resolution (arcseconds/pixel)
