Excellent eyepiece.
Just be aware it requires a position farther in than the in-most setting of the Paracorr to optimize it for coma correction. Not much, though--you're only 2.5mm away from the ideal position when the Paracorr is used in setting A.
It cannot be brought to focus using a SIPS focuser without moving the SIPS lens away from the ideal position.
