For long
throw operations, I like a product called
Telrad. When properly gaffed down it is very effective. I use it quite often on my
Lycian Super Trooper 2k spot light (it is very huge and is operated from the side). They go for about $43 (search froogle.google.com) with shipping and are designed for telescopes. I agree that one should be framiliar with a spot light where scopes are not needed but there are many times where it comes in handy. For instance in a very bright
wash your diffused spotlight dissapears at 200 feet, or you need a very quick and tight
pin spot on someone's head. I appreicate it when tours come through with Telrads for these reasons, and because you are seeing the show for the first time, it is easier to hit your
mark as called. I am even thinking of buying one personally for the shows that do not travel with them, just to make my life easier. Hope this helps.
