The last few times i have been out imaging i have been loosing the guide star for some reason.
Also using PHD2 multi star guiding
A bit hard to pin point what is going on yet, the only thing that has changed is my scope and tuned up the worm worm gears to reduce backlash on the AZ/EQ6
No binding on the mount, so that part is good.

I will have to take a shot of the PHD2 graph next time i get a clear night, can't remember what the numbers were now off hand.

The only thing i haven't tried in PHD2 and only just now realized it, is to run the guiding assistant to see what it comes back with.

But was just thinking an OAG might just improve things just that little bit more.
Hmm.....
Losing a guide Star could mean many things like PHD2 settings , PHD2 calibration or Guide scope focus, or really poor conditions like high cloud etc.... An OAG won’t fix these issues

Attached are my settings using the Orion 60mm guide scope ( focal length 240mm ) and ZWOASI120MM-S guide camera ( pixel size 3.75uM ) for PHD2 Multistar guiding
Also my procedures and notes on using PHD2
They may help , they may not
But at least you can check and compare

Cheers
Martin
