Just looking for some advice,,,  I have a Burris, Timberline 3-9 and want to focus it before slapping it on my rifle. 
I got the Ballistic Plex cross hairs pretty sharp, but it seems I can turn the eye piece several times without the sharpness changing.  Should I worry about the object being focused too?
Am I complicating this focus thing too much?
All comments welcome.

Object focus on a 3-9 will not occur inside ~10 meters/yards.  Reticle focus against a blue sky or blank wall.

  I also keep a high contrast no hunting sign (black letters on bright orange) on my 100yd target that I fine tune the focus to. Most of the time it doesn't need it if you do as Palehorse does. Just don't let your eye adjust it's focus on the reticle by looking at it too long.

With the fine threads of eyepiece focus, it may be difficult to find the exact perfect spot, but if you are close, it is likely good enough.

Generally, it is not a good idea to do this handheld.  Hand tremor will make it difficult.  Try to sit the scope on something solid (I usually do this once it is mounted on a rifle).

Also, make sure you are at the highest magnification.

Also note if you are in vision purgatory like so many of us geezers that require reading glasses you ususally have to make a choice of with or without your glasses. I generally focus w/o as I can see distances pretty well and I don't have to read much while hunting. While I don't like their looks too much I have come to appreciate the european style fast focus eyepieces more and more over the past few years as opposed to the traditional weaver /leupold threaded tube with lock ring.

Trouble with the European style is you cannot lock them down.  The ones I have are moving on me all the time.  Drives me crazy.

  I can appreciate that and that was my main concern about getting scopes so equipped.  Among different brands it seems they do vary in tightness though.  I'd say they probably vary even among the exact brand/model.  I've got only 4 scopes equipped with them.  My Conquest 4X is the tightest and I do mean TIGHT. It's not going to move.  My 2-7 Viper is next in tightness and while no where near as tight as the Conquest it hasn't moved since I mounted it.  I'm using it all this season and so far it's stayed put.  I also have 2 Weaver GS scopes. NICE scopes but the eye pieces will move when you don't want them to.  All in all I do like them as it seems with age I've aquired "variable vision".  Not that it changes every day but when it does I can easliy tweak the focus of the scope.
