Guiding issues

doctorharris

: when I try to choose a guide star , my calibrations are always alerted. I have done a good polar alignment and telescope sync. Calibration routines imply poor axes and may indicate severe backlash especially in declination axis. I also have concerns about equipment balance as well. Any suggestions on getting this minature version of PHD2 working well?

If it complains about poor axes, that may indicate the camera isn't mounted orthogonal to the RA/Dec axes.

On mine (using an ASI174MM-mini guide camera and an Orion ST-80 guide-scope) I had to bump up the Max RA & Dec durations (in milliseconds) just slightly from the defaults and it started behaving well for me.

Which mount, scope, and guide camera are you using?

Is your camera installed so that it is "square" to the movement of the RA & Dec directions of movement?

I had not considered that and, actually, the axes were not aligned with the scope axes. I will correct that next time. I hope it turns put to be thst easy! PhD2 seems mysterious until you get the hang of it but everybody uses it so i am sure the ASIair app will work too. I love the unit so far, control and plate solving are great.
