Really wide fields

Here are a few pics of many taken over night. All have a meteor trail in them. Pics 2 & 3 are sequential ie the same meteor trail on two frames.

Details
GSTAREX camera, lens focal length 1.98mm at F1.9, exposure 64 frames integrated corresponds to 1.3 seconds exposure. The field of view is about 150x115 degrees. The diagonal is close to 180 degrees.

This lens performs even better than I expected. At a dark sky site can double the exposure to 2.6 seconds. I will have to mount the camera higher to clear the trees.
North is to the left where you can see Orion and to the right you should just be able to see the LMC.
