A bit of a disaster this, for all sorts of reasons…
I had to abandon half my subs for the final image because of heavy dew that had frozen on the camera lens. Because I was worried about the dew I’d bodged up an extra large dew shield for the lens, but it drooped and ended up in the field of view. And whilst I was fitting the dew shield I must have messed up the focus setting.
So, lots to work on for next time. And time to make up a dew heater for the camera lens I think. I am currently (Hah! See what I did there?) looking up specs and prices for nichrome wire.
