After one last long look tonight (dodging clouds), I have decided to keep my 19mm Panoptic and sell the 21mm Stratus. This decision came after a number hours spent looking through both eyepieces. The Stratus definitely wins in the ease-of-use category. You can look into it from practically any angle and see the full field. The
Panoptic wins in the aberration category [ aberration(panoptic)=0.5 x aberration(stratus); small = 0.5 x small ]
