Initial Setup of PHD2 - Correct Settings?

[Pat Curran]

Hi All,

I am having trouble with PHD2 guiding, but before I upload logs can I ask if the settings for my rig are correct per attached screenshots from the 'Brain' (Advanced Settings)

I have a Comet Hunter Mak-Newt (731mm FL) on a CEM70G mount guided by an ASI220MM Guide Camera (4um pixel size) via OAG. The rig is controlled through N.I.N.A.

Anyone see anything which might be causing PHD2 to not guide correctly?

Thanks,

Pat

What issues are you having? The settings look ok but you have to remember that PHD is trying to compensate for everything else, flexure, mirror movement, mount inaccuracies etc

Thanks David,

Appreciate the confirmation on the settings.

I had a guiding graph all over the place on Saturday night but was guiding with quite a bit of wind. The stars in the guide camera view in PHD2 were elongated, which I assume is movement in the mount caused by wind. I'll post the logs tonight.

1. "Saturation by Max ADU" in Advanced /Camera is 255 for the ASI 8-bit camera driver, 65535 for the 16 bit driver.

2. Elongated stars are not unusual with an OAG.

The prism is positioned at the edge of the light cone, where star shape is often poor.

PHD2 will cope.

3. "Auto restore Calibration" in Advanced /Guiding, choose ticked or not after reading the description in the PHD2 Instructions.
