+1 on the Takahashi finders , as Lewis says .
The 30mm Tak finder on my sky90 is better than the generic 50mm one on my Istar but the 50mm Takahashi finder on my M210 is the best I have ever used , as Lewis said these are as good as some larger refractors .
Expensive , yes and I don't know how they do it and they are just so good its scary ! .
SV have a good reputation tho and are quite a bit cheaper .
