I've read again the thread on CN about the "SharpStar 15028HNT" and what I can say is that it requires a full rebuild before using it...
You also need a very expensive collimation laser tool for it. Only after lots of work it can be used to produce good images.
For the price, I wasn't expecting this. And I don't think this scope is going to be easy to use at a very remote location like mine...
