Ademco 3" Dome

[Guest anguscanplay]

cant believe im agreeing with Angus here

but there is a back focus screw on this that should need adjusting

you can do it on your workbench first before fitting the unit - advantage is then when you zoom it to cover the area you shouldnt need to refocus ( lock down the little adjuster arm too so it doesnt move over time )

Thanks for your help; I will try it again later, out flying all day today
