Check out ' Astromart ' Rom and go to reviews , then Refractors , and on the 2nd page of reviews about 1/2 way down is a review of one of these , except its the 50mm version ,
These are that good , that people use them as stand alone telescopes ,
A ' Nano ' or ' Sparrow hawk ' scope ,
these are called in the States .
Cool little machines .
Good luck Rom .
and to the buyer , super collectable.
