What scope are you using the eyepiece with ?

Is it the ES 24mm 68 degree or the 24mm 82 degree eyepiece ?

Based on the price, it's most likely the 24mm ES-82 and the OP is probably seeing the "ring of fire" common in the Televue Type 5 Naglers and their clones, like the longer focal length ES-82s.  Unfortunately, it's perfectly normal for these eyepieces.

Yes, this chromatic aberration of the exit pupil, or CAEP, is common in longer focal length ultrawide eyepieces, making them less appropriate for daylight or lunar observing.

Fortunately, those are two uses less likely with long focal length eyepieces in astronomical telescopes.
