Wrong focus star - how to find the last one used by Robostar?

Voyager Autofocus & Robofire
1

Hi
I’ve noticed in my last session that the captured images were getting out of focus over time, despite refocusing every 3-4 images.
I’m running the same sequence tonight, this time sitting next to the computer.
I found that Robostar was pointing to a double-star, the bigger one being significantly larger than its companion.
The focus routine ended up with a slightly defocused image, each time I was observing the program doing its magic.
I’d thus like to remove that double-star from the list of candidates.
How can I find that double-star that was used by Robostar?
I searched into the logs of course, but honestly, there’s way too much info there!
Any suggestions?
Many thanks in advance,
Rodolphe

Hi Rodolphe,

AI usually skip itself the double stars, if you want you can get the name of the star used looking at monitor text or opening the log file. Copy and paste the name of the star and save in the wrong focus star manager:

Here like reported in Monitor Text (log is equal)

Thank you! BTW, I also noticed that sometimes Voyager points to double stars for focusing in both of my profiles.

In this case use the wrong focus star manager, was created for this scope.
