Nice work Midas. At first blush (still working on my first cup of java too), let me ask if you have ever shot in RAW (NEF) format. I'm not sure if your post processing will handle it, and if not, then .jpeg is the best option for you. I'm a believer in capturing all available data in a photograph, and that is the benefit of shooting RAW image capture and let the post processing have a more robust chunk of information to chew on, and therefore you should see a bit more sharpness in the finished product.
The moon really captured my attention since I am fully engaged in preparations for tomorrow nights' full eclipse. I'm guessing you relied on your Auto Focus in that shot rather than using Manual. You cannot rely on simply setting the focus on infinity either, as that may or may not be the best fine tuning on various lenses. For absolute best clarity when shooting the moon is to use a very stable tripod and employ a shutter control method which raises the mirror first to avoid camera shake in the image. My choice also is to use a remote shutter control, either wired or Infra Red control. Since I cannot see the meta data associated with your shots, I cannot see or comment on f-stop or shutter speed settings/recommendations.
Best technique I've learned for capturing birds in flight is to employ my multi-shot, high speed shutter function (I get up to 5 frames per second) while maintaining optimum focus with what is called "back button focus" whereby you assign your auto focus functionality to an alternate button on the back of the camera. It is not intuitively obvious at first glance but once you read about and start using that feature, you will find it quite effective for maintaining positive focus control. I have programmed each of my cameras for back button focus, and that's the way it is for all my shots.
