RE: [APML] recommendations for development of tech pan



I use Kodak HC110 developer dilution B for eight and a half minutes at 75ºF.  That's the equivalent of 12 minutes at 68ºF.  HC110 produces a little less contrast and speed than D19.  I like the developer because it is a liquid syrup and is very easy to mix for one shot use.  D19 is a powder and the entire packet has to mixed so its' useful shelf life is less.  Powdered developers are also difficult to completely dissolve and the little left over grains add to the clean up work on the negatives.  The HC110 is just more convenient for me to use.  Michael Covington has an excellent article on his web site and he also covers the topic in his book, Astrophotography for the Amateur.  The web address for the article is:
