I recently purchased a Nikon ed50, which by the is a fantastic scope, with the 13-40x eyepiece. I was sea watching yesterday and the magnification seemed lacking when searching for far out for terns, skuas etc..........i was wondering if the spotting scope 80 is any good, just as a second scope for sea watching, and will the eye piece i have fit it......having bought the ed50/eyepeice i don't have many pennies left.....suggestions???????
