Very interesting. Explore Scientific 24mm 68 degree owners will be very pleased that this eyepiece did so well

I shouldn't think these are cheap and honestly would have expected a better performance from them.

If you were only told that the comparison was between a 6 element/4 group Panoptic copy and a re-boot of a 5 element/3 group (pre-Televue?) modified Plossl line I don't think this result would surprise anyone.

I suppose on the face of it this confirms again that different makes of eyepieces at the same focal length can react differently depending on the target they are tested on. Obviously seemingly some makes and designs of eyepieces perform better on one type of target and on another target then perform not so well than a eyepiece at the same focal ratio. Horse's for courses I suppose, no one eyepiece performs best on everything and therefore does that mean a dedicated astronomer needs to get different eyepieces at the same focal ratio and choose the target he is targeting and get the best eyepiece at that focal length for that particular target?. Going to need more money and a bigger eyepiece case if I need say four different eyepieces at the same focal ratio to get the best possible views?
