Hi Christian.
Ok, you’re running an older version of FocusMax than me, v4, while I’m running v5.
Unfortunately I don’t have any copies of v4 still installed on any of the PC’s or VM’s that I have access to and I can’t remember how v4 is configured for AcquireStar.
If you can supply a download link to a few of the images that won’t plate-solve so that Bob can test them against a working copy of PinPoint and hopefully he will also know why the wrong filter (blue) is being selected for pointing and focusing while FocusMax is running an AcquireStar autofocus, even though ACP is configured to use filter 0 (luminance) for FocusMax v4 AcquireStar autofocus.
00:57:36 Selecting Luminance filter (0) for imaging
00:57:36 Do requested auto-focus...
00:57:38 [flip check: Tn=300s HAc=-10887s GW=F HAz=-10587s DWz=F WF=no]
00:57:40 Switching from Red to Blue filter for auto-focus
00:57:40 Focus change of -26 steps required
00:57:47 (AF will use 16 bit readout mode)
00:57:47 Starting FocusMax AcquireStar autofocus...
William.
