Patch My PC Updater scans the installed programs on the PC it is run on when you start it. The program requires an active Internet connection, however. You can run Patch My PC Updater directly after the download as it does not need to be installed. You can, however, download and install updates that are available using Patch My PC Updater. ![]() As recently as the 1980s, even professional astronomers could only dream of such instantaneous communication and proc- sing ability.We reviewed the program back in 2011 for the first time, and the release of version 4.0 was incentive enough to publish a new review.Īs is the case with update-related programs, it is limited by the supported software programs that it has in its database. Developments can be e-mailed to other interested amateurs in real time, during an observing session, so that when a cataclysmic event takes place amateurs worldwide know about it. In the modern era digital images can be obtained in minutes and analyzed ‘on the fly’ while more images are being downloaded. However, even those telescopes took hours to reach such limits, and then the photographic plates had to be developed, fixed, and examined by eye. Such limits would have been within the realm of the 100- and 200-inch reflectors on Mount Wilson and Mount Palomar in the 1950s, but no other observatories. An amateur equipped with a 30-cm telescope and a CCD camera can easily image objects below magnitude 20 and, from very dark sites, 22 or 23. ![]() Today, at the start of the twenty-first century, amateurs are better equipped than any professionals of the mid-twentieth century, let alone the nineteenth. The brighter variable stars were monitored, but photography was in its infancy and digital imaging lay a century in the future. The Moon and planets, as well as bright comets, were the key objects of interest. In the Victorian era – or for non-British readers, the mid-to-late nineteenth century – amateur astronomy tended to center on Solar System objects. ![]()
