... something that works like a diagonal with a small dob like the Skywatcher Heritage 130p? I tried the diagonal of my refractor, but 1. it doesn't work so well with the dob and 2. it is very uncomfortable to use because of its shape, particularly if the dob is used on the floor. I suspect there is nothing...?

The reason why I would like to view images as they are and not inverted is mainly for constellations because they are a bit more difficult to recognize when I look at the screen in Starry Night, although of course I could also use real charts and move them around as much as I want so I can see what I see through the telescope, but I am sort of Starry Night addicted because I love how the sky changes so I don't have to check the time again and again...
