image quality isn't the best either even for a top of the line scope. it's definitely not a 600/4. with a body like the D300s on a 600/4, can crop to the same FOV as my Pentax PF-100 scope with about the same quality. however for actual looking through, i have an eyepiece for 180x magnification which is why i have one.
The problem with scopes though, is that the max apertures are often f/8 to f/11. So, manual focusing with it is a pain. I rented a Pentax scope and adapter last year to see if digiscoping is for me, but .. it wasn't. The VF got too dark and ... well .. long story short, it's not a 500mm f/4 or 600mm f/4.
