I've looked through mine and will readily admit that I am barely a novice, so take this with a grain of salt: my reaction was that they aren't very particularly relevent to someone with any level of ok gear. This is an opinion based solely on looking at moon / jupiter, though. I can see the point of them but as I say, I don't know that they have any when you've got "a better one". Personally, I'd rather look through my finderscope
