Before we start a project to actually take a detailed\nphoto of the AO-40 in Space, could someone work with me directly to\ndetermine the coordinates that we could provide as requested:\n\n>>\nHi Samudra,\n\nWe would have to know the exact coordinates ahead of time, point the\ntelescope there, then start imaging as it flies through the field of\nview.\n\nSince we've never done it, I don't know how doable it actually is. I'm\npretty certain we don't have the cameras...\n\nIt's possible, but we would need more info and possible differetn equipment.\n\n>>\n\nThe group I approached is a reputable one associated with their own\nobservatory, locally to the Washington DC area. If anyone is\ninterested to help out with the mathematics required, please contact\nme directly at [email protected]. I know of two other groups who can be\napproached locally, but we must given them all the details of\nsize/configuration etc. Could be an interesting intellectual challenge\nwhile people are waiting for new sats to be designed.\n\n-samudra\n\n\nOn Thu, Oct 15, 2009 at 5:30 PM, Peter Guelzow <[email protected]> wrote:\n> Hi Robert,\n>\n> that's indeed the big question...
