Chuck, I have a 135mm Zuiko lens. I thought I'd try and experiment with both lenses. How many minutes should I keep the shutter open? Will 5 minutes be long enough or should I try 2 or 3 minute exposures or a combination of exposures? I don't have a 200mm lens yet but I guess I'd have to learn hand guiding for anything above 135mm, right? Debbie
