I am using MaxIMDL. And I attached CFW-402 to STF-402. There is no CFW-402 in the filter section. What should I do now?
Just select SBIG Universal for the filter wheel driver. Then set Model to Standard. That setting is used for all modern SBIG wheels.
I am not sure what you mean by the "filter position has shifted". Can you send a screenshot of what you are seeing in MaxIM DL?
