Im using an LT6 which has is an f/10 scope. Light pollution is not too bad. Perhaps the UHC-E may be the choice to keep the image from being too dim. However Im not in any hurry for the purchase so if you would like to leave a comment after you recieve your UHC filter, I would be very interested in your comments about using it. So the feeling I get is that the UHC will be darker but have more contrast than the UHC-E, reinforcing the fact that the UHC is better for larger scopes?
