Looking for red dot sight for use with angled scope (1 Viewer)

Hey all,

I've been browsing these forums and the 'net for an answer to this:
When digiscoping I want my camera to be attached to the lens. Finding the bird is then quite hard (when the camera is not attached I use a method with a tie wrap, but that won't work with camera attached). I'd prefer a red dot sight that can be attached to the hot shoe of the camera, but since my scope is angled I need to be able to change the vertical angle of the red dot sight. I've seen sights that can be attached to the scope itself, but since I always have my cover on my scope I don't think that would work well enough.

So, does anyone know a red dot sight which can be attached to the hot shoe and allows for changing the vertical angle ?

Thanks,
Paul

I'm a bit confused about laser sighting. I fired a green laser sight to align my camera and frightened every bird on the river. Is the red dot out of their visible spectrum?
