Hello! Thanks for the comments.
I was surprised those mirrors fogged - the sextant was on the shore with me almost since the morning, I did expect it to be quite acclimated already...
The mirrors were recently washed with Prozone (by "Multicore" vendor of liquids for cleaning printed circuit boards).
May be indeed it was because of my breathing - I did not pay any attention for that.
How much dilute a shampoo must be? As I guess - I must apply that liquid well before the session?
Thank you again!
Warm regards,
Tony
