Hi There
Can't get intouch with Mike
ozstockman (Mike) regarding getting Bahtinov masks made up. Can someone advise me. I have a C8 focal length 2000mm but i image via a 6.3 focal reducer that make my scopes focal length 1200mm.
There is a site where you configure your own mask and download the template

but david is not replying at the moment.
Do i configure my mask to suite 1200mm or 2000mm focal length?
