Can't get a graph in PHD

[Veracocha]

Had a good few hours getting QHY5/PHD working tonigfht and it seemed to stick with the chosen star but I can't get the graph to display the results. Graph is enabled but nothing to see. Any advice appreciated.

im stuck on this too. in phd on the bottom right it says no cal i need to know what this means?

If it says no cal then you have not completed the calibration routine for some reason. When you start PHD click on the camera icon first - the bottom of the screen changes from no cam to cam (assuming it finds a guide camera!!), then the scope icon, then the curly blue arrow to start taking exposures so you cn see the stars and pick your guide star - tap the scope so you can spot the occasional hot pixel - they don't move, then click on PHD and the calibration process will start - this can take quite a while! then the screen will say "guiding" at the bottom and you are done. You will then see the red and blue lines start to cross the graph.

Hope this helps to get you going

I have stuck to that routine and the cross stays with the stars so it's tracking well but I just don't get a readout on the graph.

Does the box and cross-hairs turn green and the word Guiding displayed on the bottom of the window ?

Unless it has performed a calibration run and started guiding then no graph will be produced. As Biz has pointed out, you basically work your way through the buttons from left to right, so it's connect to camera, connect to scope, start capturing (having selected a suitable guide star), then click on the target button. This should then start a calibration run the first time used, and then change the cross-hairs to green when completed and guiding has started. Select Tools > show graph and you should get a trace.

Yep, box solid green, cross hair remains with the star and mount is moving in unison. Guiding very well but no plotting on the graph.

Have you accidentally changed the colours of the RA Dec traces on the graph - or are you looking at them through a filter or night vision settings? Click on the RA/Dec box and check - you may be watching black on black!!

[Veracocha]

No filter/night mode. Just don't understand it. I don't intend to let it bother me unless when I start imaging (Galloway 3) my stars look bloated. Cheers though guys.
