  • Observing Galaxies in Pegasus 01 October 2015 23:07
    Observing galaxies in Pegasus 01 October 2015 23:07 Context As you look towards Pegasus you are looking below the galactic plane under the Orion spiral arm of our galaxy. The Perseus-Pisces supercluster wall of galaxies runs through this constellation. It stretches from RA 3h +40 in Perseus to 23h +10 in Pegasus and is around 200 million light years away. It includes the Pegasus I group noted later this document. The constellation is well placed from mid summer to late autumn. Pegasus is a rich constellation for galaxy observing. I have observed 80 galaxies in this constellation. Relatively bright galaxies This section covers the galaxies that were visible with direct vision in my 16 inch or smaller scopes. This list will therefore grow over time as I have not yet viewed all the galaxies in good conditions at maximum altitude in my 16 inch scope! NGC 7331 MAG 9 This is the stand out galaxy of the constellation. It is similar to our milky way. Around it are a number of fainter NGC galaxies. I have seen the brightest one, NGC 7335 in my 10 inch scope with averted vision. I have seen NGC 7331 in my 25 x 100mm binoculars. NGC 7814 - Mag 10 ? Not on observed list ? This is a very lovely oval shaped galaxy. By constellation Page 1 NGC 7332 MAG 11 / NGC 7339 MAG 12 These galaxies are an isolated bound pair about 67 million light years away. NGC 7339 is the fainter of the two galaxies at the eyepiece. I have seen NGC 7332 in my 25 x 100mm binoculars.

  • Star Clusters in Local Group Galaxies 3
    Massive Stellar Clusters ASP Conference Series, Vol. XX, 2000 A. Lan¸con & C. Boily, eds. Star Clusters in Local Group Galaxies – Impact of Environment on Their Evolution and Survival Eva K. Grebel1,2 1University of Washington, Department of Astronomy, Box 351580, Seattle, WA 98195, USA 2Hubble Fellow Abstract. Star clusters are found in ∼40% of the Local Group galax- ies. Their properties are reviewed. The impact of galaxy environment on the evolution and survival of star clusters is discussed. Possible evi- dence for cluster formation triggered by galaxy interactions, gradients in cluster size, metallicity and stellar content with galactocentric radius and variations as a function of galaxy type are briefly summarized. 1. Introduction Star clusters in Local Group galaxies comprise a wide range of roughly coeval stellar agglomerates ranging from globular clusters to associations, from very metal-poor objects to clusters with solar and higher metallicity, and from ancient populations to embedded young clusters. Three basic types of such clusterings are observed: globular clusters, open clusters, and associations. 1.1. Globular Clusters Globular clusters are centrally concentrated, spherical systems with masses of 4.2 ∼< log M[M⊙] ∼< 6.6 and tidal radii ranging from ∼ 10 to ∼ 100 pc. They are bound, long-lived (∼>10 Gyr) objects whose lifetimes may extend to a Hubble arXiv:astro-ph/9912529v2 30 Dec 1999 time or beyond, though due to various efficient destruction mechanisms the presently observed globulars are likely just a lower limit of the initial number of globular clusters. Globular clusters have been observed in all known types of galaxies, but many of the less massive galaxies do not contain globular clusters.

  • 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.
