New 071 Pro Strange Whisps ice/dew?

ausgazer

Hi all. Used my brand new 071 pro other night. Cooled down to -10 over 10min. Outside ambient temp about 6 degrees . The Top of my stacked picture shows a smear about a 1/3 way from the left. Window heater was on . I can see something in the subs in the region that the whisp appears . Some people are pointing to dew or ice forming. I'm going to run another session this time cooling to -10 over 20min via SGP. The whisp appears at the top of the pic. My dslr with same scope flattener doesn't have a problem. Any ideas appreciated. New camera and I'm worried this 071 has a ice problem.

we are not sure when was this camera produced so although you bought it new but the desiccant tablets may last power

but redry desiccant tablets always work and you can tell us if it happen again
