If it is only a week, I'd wait and see if it is problem. You might find that if
you are not touching the focuser while viewing, it won't be a problem at all.
If it is a problem you can search though the archives of this group and find
many posts about changing focusers. My wife's Orion ST-80 is fine for everything
we use it for (white solar filter, Moon photos) but I do not do daytime Ha.
