Re: Explore scientific 11mm 82 with paracorr2
The data I have seen says that all the ES 82 1.25" eyepieces (14mm thru 4.7mm) will use the "B" setting when using the 2 to 1.25 adapter that comes with the paracorr. At least start there and see how it works for you. Its not really reaching optimum focus here, its about clearing up the coma in the outer part of the FOV.

Re: Explore scientific 11mm 82 with paracorr2
it is a 15 inch with 4.2 focal ratio. B setting worked. I fine tuned it to the best focus. I don't remember if it was slightly above or below B.
