What does Parfocal mean?
Eliminate the need to make focus adjustments when changing telescope eyepieces.（There will be deviations when used on different telescopes, fine adjustment is required）
This matters for those of us who tend to buy eyepieces from different manufacturers, and then are left with the mess of having to refocus after an eyepiece swap. It matters to me because when comparing eyepieces and the seeing settles down for a few seconds, I like to pop in another eyepiece and make my comparison during those brief moments of identical seeing. If the eyepieces are not parfocal, I waste precious seconds focusing, and then waiting for the vibes to quit.
