Ari,
My laptop screen is not known for being the best quality view.
Do you see an adjustment screw down toward the bottom? Line up the view in the rangefinder so that you see a sharp image... no "double vision". Once you can get that, set your extension to where it shows on the bed (mine was a Nikkor-W 135mm). Once you've got that set, adjust the arm until you can focus (with a loupe, preferably) at infinity. Once you've achieved this, your rangefinder should be aligned with your lens. While you can change lenses, you can only calibrate the rangefinder for one at a time.
When I had mine, I found this to be a nuisance, so mostly just focused with the ground glass since most of my landscape shots weren't too active. I always had time to focus. If you're into shooting something else, you may need the rangefinder more than I did.
Sorry I can't be of more help. It's been about 7 years and I may be confusing the Wista with the Busch Pressman's Kalart finder, mounted on the side.
Let me know if I can be of any further help (if I've been any at all).
Chris
