With your 12” dob light bucket you should be impressed by the difference between the 22 nagler and the 24 panoptic due to the size of 2”eyepiece lens, and it’s tfov. It’s more about matching the eyepiece to take advantage your scope/s attributes and capabilities. I would keep both if budget permits and if you have smaller scopes that utilise 1.25mm eyepieces all the better!
enjoy !
