    Hi Andres, with regard to the welding filter. Because I used teleprompter glass, about half of the light is already filtered out.This also makes the lower dots brighter, because more of the light is kept between the two glass planes. I had no trouble with the top images, although I am not in the Equatorial zone; so putting two of those shades on the lanyard might be a good idea.
