Hi Joachim,
Good explanation!
My series of pictures was not meant to demonstrate any shortcoming of the cable tie sight, but only to show that the reflex sight allows the birder to move his head around a bit and still get a perfect sight picture.
That's more a question of convenience and relaxed use than one of accuracy, aided by the sight image being easily visible with both eyes open.
This also facilitates the "reverse aiming" process ... is there a common birder's term for this, by the way? I'm thinking of picking up a bird through the scope, and then informing the birder next to you where to point the scope to see the same bird.
My hope is to devise a mount that's not as flexible as the test rig so it stays true. The test rig is fairly good vertically, but due to the use of tripod screws for mounting to the scope, it's not so good laterally. I can "bend" it into position in a similar way you describe for the cable-tie sight, but it's no fun. The sight itself stays true reliably - despite its low cost, it's quite nicely made from metal. Pleasant surprise when I opened the package!
Trueing my sight is relatively easy, but I'd still prefer to do it only at home as it requries two different sizes of hex keys - one to unlock and re-lock, and the other to adjust horizontally/vertically. Other airgun sights don't have the locking screw, and their adjustment screws can be turned with a coin ... much more user-friendly.
Regards,
Henning
Hi,
well I think the tasks of getting a bird inside the 15/1000m fov (that makes 5/333m for better comparison) of a scope at max magnification and hitting a large mammal into the heart at 333m with a rifle (shudder, sorry for mentioning it) are about two orders of magnitude apart in precision needed - which might explain why the cable tie sight works in case of the former.

I know the ordeal from my Quickfinder on the astro scopes... but of course it also needs a bit more precision and luckily holds collimation well.
