Maria and Eric Muhlmann Award Dr. Pieter van Dokkum The Maria and Eric Muhlmann Award is given for recent significant observational results made possible by innovative advances in astronomical instrumentation, software, or observational infrastructure. The recipient of the Muhlmann Award is Pieter van Dokkum for the development of a novel means to measure very diffuse and faint structures in the sky. There are now 48 lenses in two clusters that can reach a limit of 32 magnitudes per square arc second in a hour exposure over a large field of view. This very inexpensive by comparison telescope can outperform the world's largest telescopes in finding very diffuse galaxies and circumgalactic material.

Amateur astronomy

Learn how and when to remove this template message While a number of interesting celestial objects are readily identified by the naked eye, sometimes with the aid of a star chart, many others are so faint or inconspicuous that technical means are necessary to locate them. Although many methods are used in amateur astronomy, most are variations of a few specific techniques. Star hopping Star hopping is a method often used by amateur astronomers with low-tech equipment such as binoculars or a manually driven telescope. It involves the use of maps or memory to locate known landmark stars, and "hopping" between them, often with the aid of a finderscope. Because of its simplicity, star hopping is a very common method for finding objects that are close to naked-eye stars.

Share on Reddit Have you seen this on YouTube yet? The United Kingdom is a terrible place to use a telescope, at least if you consider the weather. There might be one clear night a week, or worse. So it probably takes a certain amount of bravery for somebody like John McKeon to invest in a telescope and use it to look at the planets in between dodging clouds and rainstorms and snow. Yet, McKeon—by all accounts an amateur telescope enthusiast—spotted something to spark the interest of a professional.
