Hello starhopper, hello Chris,
if you are also Moravian user, you also may suffer from in opinion bigger issue:
If yes, perhaps you can asdress this issue also in your mail? But I am not sure, if I understood the problem with the filter wheel correctly and if it is adequate to write (once again?) a mail to Moriavian.
Please keep us in the loop, if you contact Pavel.
Best regards
Reinhard
