Red Circle Finder
I have used a TelRad for 15 years or so. Can't remember changing the batteries.
I am trying a Rigel QuickFinder on my latest scope as it has a 4 deg circle and a 0.5 degree circle like a TelRad. It is smaller and neater but I am finding it more difficult to use. I think it is because the long body of the TelRad gives a good clue as to where to position the eye and the short body of the QuickFinder doesn't.
The QuickFinder has a ghost image about 20 deg away from the main circle which initially confuses but eventually helps when you realise that it is in a predictable position in relation to the main circles.
The big advantage of circles over dots is that they allow you to offset or step by a known amount. This is enormously important when aiming for objects not visable to the naked eye where you have to offset from a nearby star.
