Nup, itís a cheap GSO knock-off.

APO? hummm....think I might have one kicking about somewhere in the shed.

Seriously though, the scope Iím using has no, zero, nada, nil flexure issues. All sky variation is around 1/10th of an arc second, which may simply be refraction or a CCDinspector artifact. With A KAF8300 sensor results were indeed perfect...but the KAF16803 random, and to be fair very tiny, variations have me puzzled.
