Hi Allan,
Thanks for replying
I did learn from my research that rear port of 4SE is not a SCT thread, hence the intention to first screw on the Baader Mak to SCT rear thread adapter to 4SE(Baader part no. 2958500) and the visual back to the back of adapter with SCT thread. This opens me up for a big range of SCT accessories available out there. The I wanted to use the start diagonal on the visual black and then mount the camera in the star diagonal. Similar to this pic
