Highly systematic technique is obviously required; remarkable images requiring remarkable discipline and patience. The Helicon remote described by GURL (http://www.heliconsoft.com/heliconremote.html) sounds like the right kind of tool for those that would pursue this approach.
Concise and clear; thanks for sharing your experience and technique.
I can't get focus except front and back extremes. I.e., nothing in the middle range. Is this an intrinsic short-coming or is the image just a simulation?
