Title deliberately ambiguous.  Excellent astronomical seeing is essential for a visual observation, as are precisely aligned and scrupulously clean optics.  However, I wasn’t expecting to see Procyon B through an eyepiece.  Like the travails reported by David Swan, swapping a camera for an eyepiece is too much of a faff.  Actually, it isn’t, it’s the reverse that’s painful — having to spend hours taking all the flats in all filters again because the CCD will undoubtedly have rotated from its previous position.

No, I was planning on Lucky imaging to let me see the companion.

Hmm, perhaps it’s time to retake the flats anyway …
