First imaging test, no, the clouds HAVEN'T gone away. In fact it is raining cats and dogs. So this is bench mounted in the back of the garage pointing outside through the gaps in the neighbours deck rails at a couple of Norfolk Pines about 4 km away in steady rain. ( It was the only distant target I had in the circumstances ) The 'vignetting' is actually the upper most rail on their deck intruding into the frame.
If you look closely at the top of the leftmost tree ( jpg compression and size of file allowing of course ) you can make out the pine branches and the leaf extensions individually ..
I hereby declare this build a success
Now where did I put my cloud sucker upper
??
