The closest I got to a close up was an Emperor 5m away. They rarely land so I was quite pleased. I couldn't use point focus as it was quite windy and the reeds moved too much and fast. The centre 9 points worked,

Very nice photo Erik! BTW I don't understand how you and Privatebydesign are calculating the g-force without knowing the speed of the dragon and the radius of the turn?!A hover at 80° bank would lead to an astounding acceleration.
But it is possible that the dragonfly was doing a "hammerhead" in more or less 0g. They seem to be pretty skilled in aerobatics..
So much easier to shoot when they are grounded.. Or maybe not

I was saying the same thing, you can’t calculate the g force from bank angle alone.Very nice photo Erik! BTW I don't understand how you and Privatebydesign are calculating the g-force without knowing the speed of the dragon and the radius of the turn?!
No, it wasn't hovering - it was flying strait (and I was expecting to get it closer for meaningful photo) when it made one of these nearly 90° turns (I don't know the radius of the turn either but with these guys I have seen very sharp turns!).
I was just about to post the same... calculating the g-force without knowing the speed of the dragon and the radius of the turn?! ...
In a stationary turn (without any sideslip or change of altitude), the load factor is solely dependent of the bank angle. Speed is not involved at all. Turn rate and turn radius depend on both speed and load factorBTW I don't understand how you and Privatebydesign are calculating the g-force without knowing the speed of the dragon and the radius of the turn?!
So a bank angle of 90° wouldn't be possible as the load factor would be infinite?In a stationary turn (without any sideslip or change of altitude), the load factor is solely dependent of the bank angle. Speed is not involved at all. Turn rate and turn radius depend on both speed and load factor

I don't really know how to distinguish between a white and black tailed skimmer. Difficult shots, well done.Pretty difficult to catch but I managed to get this white-tailed skimmer (orthetrum albistylum, still I'm not sure if I determite this one right) in 2 out of 20:

Thanks to the both of you for the comments and "likes".Sharp pictures. Well done, Maximilian.
Sorry Maximilian but I think it's the Black-tailed Skimmer! Great shots anyway!Pretty difficult to catch but I managed to get this white-tailed skimmer (orthetrum albistylum, still I'm not sure if I determite this one right) in 2 out of 20:
