Thanks for posting those and the story behind them.
Great work Zed, that Sony lens produces nice round stars and shows little distortion at the edges when wide open - good glass.
Like you, I prefer the simplicity of the single shot approach, but I don't mind mosaics or stacking as needed, as long as it is clear that those were the techniques used to get the result.
You have some nice skies.
I also found it quite difficult to compare the small image on the rear LCD of the camera with the FOV in my planetarium program. Next time, (2040) I might take a Notebook and do a Plate Solve to establish that I was pointing in the right direction.
Cheers
Dennis
EDIT:
You have a trail of some object in your image. It doesn't look like an aeroplane which would have multiple, coloured lights.
