I have been thinking about this since I posted my last post (above) last night. I can't explain why this is so... But I definitely notice a difference when I look through EP's with different focal lengths and the same AFOV.
Why? Why!
I thought that it might have something to do with the EP relief. Maybe when I look though some naglers I have a tendancy to view from too close to the lens. This make makes it easier to see the field stop. Could this be it?
My experience at star camps looking through lots of different naglers is that sometimes it is impossible to see the field stop and other times it's way too easy. That's one of the reasons why I'm happy with the 22mm pan, because the field is way bid enough, getting the extra bit from the nagler would be a waste. But with another focal length comparison the nagler would kick it's buttt. I can't remember whether it was longer or shorter FL that made the difference now...
I would be intrested to hear if anyone else has had the same experience. Is it an eye relief issue?
