Hi, I've just purchased a Takahashi Focal reducer / flattener, but the stars in Ha are bloated, but not in LRGB? I have checked the spacing between the QSI and the Focal Reducer that screws directly in to the 3.5" focuser. I also have perfect stars when focusing with the bahnataov mask.
I never had this issue when using a Takahashi flattener, am I missing something??? would really appreciate some help.
The only thing I can think of is that my 2" narrowband filters are in a separate filter wheel connected to my QSI camera that has an integrated filter wheel, although this was never an issue when using my old flattener!!!
