Last night and a few nights ago when it was warm and humid I have had what I believe is dew/condensation show up. It not on the telescope but could be the focal reducer or on my ASI1600 MM Pro (2018). Last night when I was shooting in OIII it started fine for about an hour and then it developed. The image is from the other night when I was shooting in Ha. I did have one successful night in between when it was a bit drier. I have had it for about two years and it has never happened before. Questions 1) Is this on the glass plate or sensor? 2) Should I change the desiccant? 3) Should get the ASI camera heater? The website indicates it is not needed for the ASI1600. - Thanks
Does it only show when cooling is on?
Please redry the camera by following this guide.

Thanks, I haven't had enough time to experiment to know if it only happens when the cooling is on. I just got done re-drying the tablets and and waiting for clear skies. Hopefully tonight...
If there is any other problem please feel free to contact us.
Thanks. I did end up recharging the desiccant tablets and that seemed to have done the trick for now. I will due the cooling slower and turn it on well before imaging as well. - Thank again. Kurt
