That's a great project.

I look forward to your results.

One point I would make about CDK designs having used a 17 inch now for several years, it would be good to minimise the vignetting. I believe there are optical compromises between vignetting and F ratio etc but I think less vignetting would be a good thing. It would make it less dependent on good flats.

Greg.
