I used a 8.8 inch wide angle Meade on my 12" LX200 the last two nights. It
would not focus right until after Jupiter was well above the horizon, after
that it got better and better and I watch one of the moons come out from
behind the planet. In order to see more detail, some of my friends from
the KAO star club held various colored filters up to it, and the was
interesting.

At this point of your message I would guess it was the atmosphere causing
your problems.

If the 9mm RET does focus, I would have waited a little longer and tried
the Nagler again. Since it has more pieces of glass, it is probably more
sensitive to problems than the RET. But I would stay up over night on some
fairly good night check it out, again.

Oh, yeh, mine unscrews a lot also. I don't think that is a problem, if it
does not come completely unscrewed (In which case the glass will all come
falling out). Just tighten it up.

Hope it turns out to be just the atmosphere. I live in Kansas and the
humidity is pretty bad here. Not to mention the farmers all burn there
fields this time of year.
