Oh, I actually got that one in Florida ! after watching it for about 20 minutes I discovered it a ha a predictable flight pattern. So I got comfortable and waited, it took about an hour for all those shots. I eventually used high speed flash to freeze the wings as I didn't have a tripod with me .
I have tried that several times with a bit of success, I use a shoulder brace and with these I have tried the monopod,,,seemed to work not bad, no flash though,,I will try again this year,,lol
