Is there a way to review autofocus performance?

When reviewing the performance of an automated run, the PDF that is created offers a lot of insight and detail, and the list of HFD values gives a lot of information on the image quality.

But there is no information on autofocus runs. When did they happen, what focuser positions were set, any errors, any fallback from localfield to Robostar, quality of the V-Curve, etc. During imaging the status-panel provides all this information and even allows to pull up a graphical VCurve.

Is there any place where I can review this information the following morning?

Quality of VCurve is something real ethereal excluded the ones done during the First Light Wizard … remember that LocalField is an average focus and not the best focus (and not only for Voyager but for all application using this method) … avoid it if you can and use RoboStar that is the best focus. LocalField autofocus is done using AI so at 99% or you have a good focus or an error. Quality of focus depend on how much is flat your telescope, how much is good your focuser

Said this answer is Yes, you can search this information in the log files.

Thanks Leo. I used RoboStar, but had a few cases where it gave me a sub-optimal outcome. LocalField so far has worked well for me. I’ve got a flat focus-field, so average is no problem.

Perhaps I should re-assess RoboStar again and use much higher binning. For focusing the quality of the out-of-focus image is important as well. And my highly oversampled system may give a more consistent image in these super-short exposures used in RoboStar when using Bin4 or so. Worthwhile exploring.

For now, I will keep an eye on things by running the Fits Data View script in PI after each session. It just takes a while to load the images in there and it is yet another step in the process. But exploring a log file with 100,000 lines would be a lot harder. Having FocusPosition and FocusTemperature in the PDF would go a long way. :wink:

Robostar must be used at binning 1 and the short exposure do not affect the measures.

Anyway if you want to focus position and temperature are inside the FIT.
You can ask for a customize development if you want to add to PDF :wink:
