Hi,
I have a Star Adventurer 2i which I'm using an ASIAIR Plus with for PA and object location. I'm also attempting to guide as well (RA only). I can generally get everything working in terms of the guiding (calibration etc), and then the graph will show a blue line tracking across it, but I note that there is occasionally no measure of RMS error displayed - it just stays at 0.
Is there something I need to do? It has displayed properly in at least a couple of imaging sessions, but also not displayed in others...
Thanks.
