Hi All
I am considering adding a premium widefield ep to my collection. I'm tossing up between the 27mm Pano, the 30mm XW Pentax and 31mm T5 Nagler. I'm leaning towards either the Nagler or the XW. I'm not sure the extra width in the FOV of the Nagler is worth an extra $300 odd though.
The ep is for my 305mm Newtonian @ f5.
Your thoughts would be appreciated.
Cheers
