Thanks @Doug and @Peter.

Indeed, I use a refractor with the RnP focuser and indeed, its very long in comparison to the NCFZ, but I think it's for the purpose of accessories I can attach.

Speaking about the accessories, I don't have the filter wheel and also have no mono camera yet, but only the Canon 6D. I use 2" filters and I think about the filter wheel to simplify my work. I.e., I think now to use an OIII filter to extract more oxygen from nebulas. But I don't understand the offset, what is it in the context of the focusing? I remember from the documentation that I can set fixed number of steps that I can add or subtract from the given by the algorithm value, am I right? Shouldn't I need to refocus then?
