I tried Kstars 3.0.0 for Mac and it corrupted things so that 2.9.8 wasn't working either. I had to uninstall everything and re-install. When it came time to enter the camera resolution I accidentally entered the wrong number and now I can't change it.

I changed the setting (max width in image info pane) in the control panel but the frame size in the capture pane won't update to this new setting.

(I'm using the Pentax ccd driver on stellar mate remotely connected to a Mac with Kstars 2.9.8 )

I don't think 2.9.8 had the ability to clear DSLR settings yet? We should be able to release 3.1.1 soon, and perhaps I can make a beta for your to try out in a while.

Thanks @knro, will deleting preferences or something clear this setting?. I'm not sure where the info is stored, Kstars or ccd driver on stellarmate?

There are a few clear nights this week so I could test 3.1.1 tonight probably

It's in userdb.sqlite file in KStars, not sure where that is stored on Mac.. where all other local KStars file are. If you have an SQLite editor on Mac, you can open it and clear all entries under the DSLR table. or you can delete it, but lose all other settings.
