Ah, but yours was blowing onto the back of primary mirror.
That is the problem with the way mass produced OTAs have the fans placed on them. Do you expect the air to go into the OTA that way with the skeletal cell they have? It won't and it can't.
And the fan blowing onto the back of the primary mirror creates a cold spot on the mirror, thereby creating a thermal strain in the glass, and distorting the figure.
What my photo shows, AND how the fan is being used is not what mass produced OTAs have.
Read that article and understand what the photo is showing. It is not all that it seems at first sight.
