There are three versions, one is free, the others are the Plus and Pro.
Only the Pro provides the additional components. The free and us only provide the 18.4".
There are Sky Safari versions for Android, iOS and Macs.
Not free, at least not here in Norway, about 2$ for the simplest- and it doesnt show α umi b either. Actually neither Stellarium nor Skysafari (simplest version) shows that. Nor Kochab. Hm..
If you don't already have it, the latest edition of the Cambridge Double Star Atlas has a good description of the AaBb types of multiple star systems, which might help alleviate some of the confusion in general. Also, Wulff Heinz's double star book can be found as a free download and it provides a really deep description of it all. I find it fascinating and delightful to observe and study about these multiple star systems!
I regularly use Polaris's ninth magnitude companion as a test for optics and sky conditions...
Thanks! Have downloaded the Heinz book, quite deep indeed!
To test optics became my general idea. If my Skymax 127 doesn't split Polaris, under good conditions, I might consider throwing it under the bus
Well, I do not have high hopes, but where I am now is supposed to be 2 Bortle, so there is a chance...
To sum up, I was not so wrong to be frustrated when not finding the right views in Stellarium, and now only have to really pin down what is considered Polaris companions that are achievable to see through a telescope.
As I understand it, the real companions are spectroscopic and are unavailable for amateur astronomer. And what people are calling splitting Polaris, is just visual, and not really related to Polaris by gravity.
Thanks for all the input and forgive my ignorance and impatience, wanting to understand everything at once.
