Thanks Troy, I used sky flats and didn't think the vignetting was that bad. But I went out last week and repeated the exercise at f2.5 so I will compare the two. I did notice that the strange split stars in the outer parts of the image changed to a more complicated type of split at f2.5 and the stars are a little tighter.
It was your image of Orion with this lens that convinced me to donate a kidney
and get this one.
Cheers,
Andrew.

The Zeiss 135 on a D810A - what a weapon! You are going to have fun with that setup. I am running the same lens on my full spectrum 6D with some very satisfying results.
Yes, there is some spiral action going on with the LMC. It showed up with my all sky imaging project that I completed some time ago using the full spectrum 6D + siggy 35mm f1.4. I could hardly believe the extent, and that no one has recently picked it up. I have never posted the result of the all sky, but might just do so.
Although Orion has been quite a distraction, I am having a good go again with the Zeiss 135. I am hoping to reveal this section of sky in far greater detail. Cheering for clear skies in SE QLD - something that is quite rare this time of year.
