I just added a .8x reducer/flattener to my WO ZS73 refractor.  I have added the lens to my equipment configuration in Ekos, but I don't see where I can actually have it added/applied for use in plate solving calculations and guiding - I use an OAG and PHD2.  The best I can figure, is I can change the focal length of the primary scope from 430mm (native) to 344mm, which is in essence what the scope becomes with a .8x reducer.  Is this the best way to have the reducer included in the calculations Ekos makes, or is there another way I should be doing it and if so, where is it in Ekos?  Thanks guys!  Tom
