Sorry, I see nothing wrong there. Yes it might be a bit disconcerting to the spotee, but once the true nature of the item is known that should have been the end of the discussion IMHO.
Spot on as usual
Roundoak,
I guess thats the "like it or lump it" position and your probably quite within your rights to stick to that stance.
However, playing Devils Advocate for a second, if the position were reversed, how would you like it?
Also, could using that set-up result in further hassle? I'm thinking what if somebody called a LEO because they felt you were using a "rifle" inappropriately?
Sometimes, just because you have the lawfully right to do something, doesn't necessarily make it a good idea so to speak...
Anyway, away from the "ethics aspect", what mag is the scope?
And is there any particular reason why you choose that set up over a conventional tripod???
I have a Nikon 50ED with a x27 eyepiece and while I can hand hold it using my stalking sticks as a steady, putting it on a tripod makes it far more effective..
Regards,
Peter
