hi David,
the W.O. fixed outperform it, but in saying that, I think I'm being influenced by the 82FOV of the WO rather than sharpness.
The Baader provides sharp images, is not too far from parafocal, and we use it for 4 particular situations:
1/ its used exclusively if we have non-astronomer guests, it lets us get an appropriate view without them getting bored waiting.
2/ if we are only viewing out for an hour or so, we usually just take it rather than the box of EP's - you spend more quality time viewing less time changing EP's.
3/ we have a smallish "travel scope" we take away in case we get a look somewhere, - the baader is all we take in the way of Eyepieces.
4/ on a normal viewing night its usually the first EP on the scope if we are trawling, because you can get the right magnification to checkout new objects of various sizes.
in other words we use it at least part of most nights. Its about convenience, not ultimate quality of view. - though it does provide good viewing.
oh, and its great with the barlow on our Newtonian (4mm = x300), but with the Mak it's magnification becomes too large to use around suburbia (4mm = x625)
hope that helps
