Hi,

I just got the Orion Highlight Plossl 6.3mm, and it definitely is NOT parfocal with the TV plossls. But it was on sale, and still is, and seems to perform well for the price. I haven't had the chance to really test it enough to write a review comparing it to my TV plossls but it does of course suffer from VERY short eye relief, and has a very small lens.

Glenn,
I have TV 8mm plossl, with the TV 2x Barlow its parfocal in various scopes.

Other brand plossls I have to refocus when adding the barlow.
