Is the scope an fpl53 triplet or fpl51 (or equivalent glass) triplet? No chromatic aberration around bright stars?

Planning on fiddling with the focuser a bit when my adapter arrives from Precise Parts, possibly not too worth while trying anything when I am using compression rings without the flattenener.
The telescope is a FPL53 triplet, I haven't yet really pushed it. From
The little I have seen I haven't seen any chromatic aberration yet. Planning on trying my 4x Powermate + 4.5mm Meade Series 5000 on the moon and some bright stars in the future. Just need a clear night with half reasonable seeing just to make sure that the sky conditions will not be a potential cause.
