Helpful - partly -

It is true that, by the additional eyepieces, the application possibilities of the reflector can be significantly improved, also because of the moon contained filter

However, the viewfinder is in my opinion unnecessary because a complete Fehlkonstrulktion! If you are looking for something with the reflector in the sky, the eyepiece of the finderscope is inevitably directed gene floor, by the low Gesamtkontruktion now one would have to lie on your back either the reflector - which still remain to solve the problem, how do I get my skull high level or the entire unit, which makes to naught the meaningfulness of a finderscope !! - in the small gap between eyepiece and footprint

Otherwise nothing to complain about for the price.
