President's Message Astro Short: Wild Weather on WASP -43b Secretary's Summary Message From HRPO IYL and 20/20 Vision Campaign Recent BRAS Forum Entries Observing Notes by John Nagle President's Message Welcome to a new year. I can see lots to be excited about this year. First up are the Rockafeller retreat and Hodges Gardens Star Party. Go to our website for details: www.brastro.org Almost like a Christmas present from heaven, Comet Lovejoy C/2014 Q2 underwent a sudden brightening right before Christmas. Initially it was expected to be about magnitude 8 at its brightest but right after Christmas it became visible to the naked eye. At the time of this writing, it may become as bright as magnitude 4.5 or 4. As January progresses, the comet will move farther north, and higher in the sky for us. Now all we need is for these clouds to move out…. If any of you received (or bought yourself) any astronomical related goodies for Christmas and would like to show them off, bring them to the next meeting. Interesting geeky goodies qualify also, like that new drone or 3D printer. BRAS members are invited to a star party hosted by a group called the Lake Charles Free Thinkers. It will be January 24, 2015 from 3:00 PM on, at 5335 Hwy.

  • Making a Sky Atlas

    Making a Sky Atlas

    Appendix A Making a Sky Atlas Although a number of very advanced sky atlases are now available in print, none is likely to be ideal for any given task. Published atlases will probably have too few or too many guide stars, too few or too many deep-sky objects plotted in them, wrong- size charts, etc. I found that with MegaStar I could design and make, specifically for my survey, a “just right” personalized atlas. My atlas consists of 108 charts, each about twenty square degrees in size, with guide stars down to magnitude 8.9. I used only the northernmost 78 charts, since I observed the sky only down to –35°. On the charts I plotted only the objects I wanted to observe. In addition I made enlargements of small, overcrowded areas (“quad charts”) as well as separate large-scale charts for the Virgo Galaxy Cluster, the latter with guide stars down to magnitude 11.4. I put the charts in plastic sheet protectors in a three-ring binder, taking them out and plac- ing them on my telescope mount’s clipboard as needed. To find an object I would use the 35 mm finder (except in the Virgo Cluster, where I used the 60 mm as the finder) to point the ensemble of telescopes at the indicated spot among the guide stars. If the object was not seen in the 35 mm, as it usually was not, I would then look in the larger telescopes. If the object was not immediately visible even in the primary telescope – a not uncommon occur- rence due to inexact initial pointing – I would then scan around for it.

  • Popular Names of Deep Sky (Galaxies,Nebulae and Clusters) Viciana’S List

    Popular Names of Deep Sky (Galaxies,Nebulae and Clusters) Viciana’S List

    POPULAR NAMES OF DEEP SKY (GALAXIES,NEBULAE AND CLUSTERS) VICIANA’S LIST 2ª version August 2014 There isn’t any astronomical guide or star chart without a list of popular names of deep sky objects. Given the huge amount of celestial bodies labeled only with a number, the popular names given to them serve as a friendly anchor in a broad and complicated science such as Astronomy The origin of these names is varied. Some of them come from mythology (Pleiades); others from their discoverer; some describe their shape or singularities; (for instance, a rotten egg, because of its odor); and others belong to a constellation (Great Orion Nebula); etc. The real popular names of celestial bodies are those that for some special characteristic, have been inspired by the imagination of astronomers and amateurs. The most complete list is proposed by SEDS (Students for the Exploration and Development of Space). Other sources that have been used to produce this illustrated dictionary are AstroSurf, Wikipedia, Astronomy Picture of the Day, Skymap computer program, Cartes du ciel and a large bibliography of THE NAMES OF THE UNIVERSE. If you know other name of popular deep sky objects and you think it is important to include them in the popular names’ list, please send it to [email protected] with at least three references from different websites. If you have a good photo of some of the deep sky objects, please send it with standard technical specifications and an optional comment. It will be published in the names of the Universe blog. It could also be included in the ILLUSTRATED DICTIONARY OF POPULAR NAMES OF DEEP SKY.

    One of the Most Useful Accessories an Amateur Can Possess Is One of the Ubiquitous Optical Filters

    One of the most useful accessories an amateur can possess is one of the ubiquitous optical filters. Having been accessible previously only to the professional astronomer, they came onto the marker relatively recently, and have made a very big impact. They are useful, but don't think they're the whole answer! They can be a mixed blessing. From reading some of the advertisements in astronomy magazines you would be correct in thinking that they will make hitherto faint and indistinct objects burst into vivid observ­ ability. They don't. What the manufacturers do not mention is that regardless of the filter used, you will still need dark and transparent skies for the use of the filter to be worthwhile. Don't make the mistake of thinking that using a filter from an urban location will always make objects become clearer. The first and most immediately apparent item on the downside is that in all cases the use of a filter reduces the amount oflight that reaches the eye, often quite sub­ stantially. The brightness of the field of view and the objects contained therein is reduced. However, what the filter does do is select specific wavelengths of light emitted by an object, which may be swamped by other wavelengths. It does this by suppressing the unwanted wavelengths. This is particularly effective in observing extended objects such as emission nebulae and planetary nebulae. In the former case, use a filter that transmits light around the wavelength of 653.2 nm, which is the spectral line of hydrogen alpha (Ha), and is the wavelength oflight respons­ ible for the spectacular red colour seen in photographs of emission nebulae.
