Frank,
Unfortunately you might now now be able to subscibe to PA anymore. As mentioned earlier, there is a lot of confusion as to its status. Those of us who subscribe got an email a month or two back saying the proprietor was having problems with illness and providing a link to a pdf copy of that issue. I have heard nothing from them since.
Pity because it was an extremely useful magazine. Almost entirly astrophotography based content. With tutorials etc. 1st Class.
