You know I did see that written down somewhere. If you don't mind I'll do a bit of investigating and get back to you on that. Alternatively check out the alpineastro website. Obviously the configuration in which it is used (one or two extension tubes) has an impact on that
What I have in my documentation says that is is designed to deliver a wide flat field for 35mm photography. Now that does not tell me much about the unvignetted field size but I aware of it being used with imaging cameras up to the SBIG ST10 MX in size.
Cheers
Lars
