Hi,
Unexpectedly yesterday night cleared up and I tossed out all my stuff and started a session. I stayd with it for the 5 pics before the Meridian flip as I wanted to observe and test it for the first time with NINA. Then I left everything to image throughout the short summer nights. i i found that every image after the flip and even one before looks like this:
Is that dew? And if, WHERE???
Because I had the dew heater running on full power, at least I thought.
The build up in the images is rather quick and it stays, so it is not going completely in. Also I am usually used to dew forming in the center and creping outwards and I looked on the lense during the meridian flip wait time and it was totally clear, but even one picture before that showed this.
Any suggestions or other explanations.
One alternative i have is, that it is dew on the camera shield as I though it would be a good idea to cool down to -20 and not jsut -10. and had the camera dew heater only set to 1 of 4? :-(
Cheers, Robert
