Not everyone is able to see the full field of view in these ultra wide eyepieces without moving. I am one, so I stick to 85deg eyepieces and below. Everyone has there own preferred field of view eyepieces so we all buy and sell to find the ones which suit our own viewing requirements.
I’ve moved a few on over the years, not because they’re bad eyepieces just because they didn’t suit me. Try before you buy if possible.
Hope this helps!
