spotting scopes are not just for waders, they are equally useful for distant raptors over woods or even high in the sky. Once you get used to your scope/ tripod combination you should be able to lock onto individual flying waders etc.
Remember , if it's windy and the tripod is shaking at full height, retract the LOWEST leg sections ( the thinnest) as that will help. Alternatively retract all the legs and squat down when scanning . ( I personally like that method).
If you don't like the rubber lens cap that covers your eyepiece, or if it's gone missing then consider making one yourself. I prefer a deep eyepiece cover as those who saw my scope photos noticed. A plastic container ( I use cod liver oil tablets ) cut to the right length and covered in insulating tape and tied to the scope foot with nylon cord ( B&Q 85p a metre) works well.
