Christopher estimates he saw about 20 meteors during the outing. He was very impressed. Michael helped setting up the cameras and managed the catering...
Anybody watching us would have thought we were fresh from the Mad Hatters Tea Party! LOL Christopher was lying on his back on the frozen ground (watching for meteors), I was running from camera to camera checking them and Michael was dishing up doughnuts and sausage rolls in total darkness, well almost, there was no moon.
Working on the meteor image, a bit of light pollution and amplified noise I think. A touch of CA, the stars are mostly pure white, so probably blown. I think 15 seconds may have been a bit too long, ten may have been better.
The 20mm f2.8 seems to need a longer exposure than the 50mm f1.4 at f4 on the same body. Don't quite understand that.
I am getting a better understanding of the median stacking process, aligning the stars is the biggest problem. Will describe it more fully in another post. I am devising a workaround, the issue is alignment of the 'rotating' stars coupled with interference from passing clouds and some other factor which is messing the Ps Auto Align up.
