Hello there!!!....just wondered if anybody has tried using a 2" GSO barlow on a 27mm Panoptic before.
If you have, was there any vignetting? did it work out ok?...was the eye relief pushed out too far ??????......any replies or experiences using this configuration or just the 27mm Panoptic by itself would help a great deal!!!
Thanks!!!!
