I posted the first panel a few weeks ago. Since then I have taken an additional 5 panels. Here is a total of 4 panels stitched.
Sony A7r2 cameras Zeiss Batis 85mm F1.8 lens at F4, ISO640 14 x 5 mins autoguided on an AP1600 mount at my dark site.

I may redo the first top left panel as it was taken under 1/3rd moon whereas the others were all done with no moon.
I also have a set of panels done with the 16803 and Pentax lens. Its a lot more work to process though but should make an interesting comparison when done.
