Can anyone varify that the ST7 with the attached color wheel, come to focus using a TAK FS78 & Tak F/6 reducer? Will the same setup (ST7 & Color wheel) come to focus at F/6.3 & F/3.3 on C-11?

Thanks

Sam

Hi Sam,

with the FS60C I had to add 30mm of extension tube to reach focus with Homeyer filter wheel and HX916. Taks tend to have *a lot of* back focus.

Sorry that I do not have exactly the same equipment...
