New and odd PHD2 problem

[Skipper Billy]

PHD2 usually behaves really well but the the last couple of sessions it seems to have developed a strange problem.

I cannot manually choose a star to guide on - if I click on a suitable star I get an amber box and it just stops taking subs.

If I click 'auto select' it chooses a gap between two adjacent stars (almost every time) - see attached screen grab.

The guiding is pretty good but it seems very odd!

Any suggestions??

Not sure whether it is related to the issue but it is also repeatedly saying Star Lost - Low HFD although the guide star is clearly visible on the screen!

I am using the latest version- 2.6.11

Are you using the'guide using multiple stars'. I've had the main green cross not be on a star but a number of little green circles sit around stars across the fov and guiding is good anyway?

Thanks Francis

I have tried it with multiple stars - and without - neither way lets me choose a star manually - maybe its because the prog. is started by N.I.N.A.  and it must auto select after a Meridian flip???

I always start PHD before NINA and then connect to it, I’ve never seen this. I had a recent update for PHD, did this problem start after the update?

No - I haven't updated a for a while and it has worked properly since. I tried restarting it half a dozen times and every time it sleeted a gap between 2 stars!

Try rolling back to 2.6.10.

I will be taking my rig to bits soon as its the end of the season for me.

Maybe there will be an update over the summer before I start again in September. If not I will try rolling it back.

I've had the same problem since updating to 2.6.11. A rig that was happily guiding from 0.5" to 1" on a bad night has gone to 2"+ on good nights.

Auto-select insists on selecting faint stars really close to my 'Minimum Star HFD' setting, and then can't sustain guiding with that star. I had to go back to manually selecting a single (saturated) star to get any guiding at all.

I've just reverted to 2.6.10, and with the same rig and the same settings I'm back to auto-select with no issues, and guiding currently at 0.75".
