I am an amateur astronomer who observes and conducts public outreach on a regular basis. I have many Moon references, in book form, plastic maps, and iPhone/iPad app formats. They all provide great information. But the one resource that is always with me and used most often outside at the telescope, is this app. It is visually stunning, versatile, readable, loaded with useful information and very easy to use. And it does not turn into paper mâché in heavy dew situations. The ability to clearly recognize and locate lunar features at various scale of magnification is a tremendous aid, whether I'm trying to find something new or in effectively conveying understanding to the general public. Thank you so much for producing and continuing to supporting this outstanding tool!
