Big Eazy on Tak

I am thinking of getting a Denk Big Easy package for my Tak FS102 NSV since I already have a pair of 30mm Ultima's. I will probably need to use the OCS. Will I get any vignetting with this setup? I have a 2" TeleVue diagonal, but the Big Easy only has 1 1/4" openings. All comments appreciated.

Thanks
Alan

Alan,

You may need an OCS with your 2" diagonal. You might not need one if you use a 1 1/4" diagonal. I have a TAK FS-128 and I can focus my Denks, Black Knights, and Burgess binoviewers without any OCS if I use a 1 1/4" diagonal.

I would think that the NSV would have even more in-travel than my FS-128.
