DMS-1 question

to those who have used/owned a millet dms-1
at illumination settings, 9 to 11, this is how the reticle looks. its like the illumination from the center dot vaguely spreads across the lens.

but when i take it outdoors at the same settings, it clear like this:

is there something wrong with the scope, or the i’m just not supposed to use high illumination settings when indoors or at dark places?

TIA

Your illumination setting is too high…turn in down a few notches and it should clear up.

thanks oscar!
