I suspected with my setup it was the spacing between flattener and sensor. Out of interest, what do you have between the 2?

Troy,
Thanks for the kind comment.
My camera is a ST8300M equiped with a filter's wheel model FW8-8300 from SBIG and a OAG also from SBIG model OAG-8300. The total back focus of this setup including the camera, is 57mm, so that I have included a 2mm ring spacer to make 59mm, that I concluded empirically as the optimum spacing between the TRF2008 and the sensor.
Even being at the optimum distance, I didn't achieve round stars in the corners, where they are a little bit elongated so, I could not escape of cropping the image a bit to get rid off those elongated stars.
Best Regards,
Fernando
