Ended up with a myriad of issues after I went to sleep last night, everything happens the moment you turn your back on your imaging setup! I have a 12V to cigarette socket that I use to power my dew prevention, let's just say that the wires had twisted (after two years of use) inside that socket and I woke up to lots of dew on my dew prevention straps
Oh and dew on everything else as well! The dew threw off the auto focus routine so I ended up with a bit of data that was dew effected and out of focus
Here is 3x300s with the D810 and 130mm around Jabbah.
