  • Binocular Universe: Here’S the Poop March 2012
    Binocular Universe: Here’s the Poop March 2012 Phil Harrington f you look at an old star map of the late winter sky created 250 or more years ago, you'll find a huge, unfamiliar constellation dominating the sky to the south Iand east of Canis Major. That's Argo Navis, a behemoth of a constellation dating from ancient Greece that depicted the mythical voyage of Jason and the Argonauts as they searched for the Golden Fleece. When viewed from Greece, the stars of Argo Navis appeared to skim the southern horizon, as if the ship was "sailing" across the Mediterranean Sea. Above: Winter star map adapted from the author's book, Star Watch Above: Finder chart for this month's Binocular Universe from TUBA, www.philharrington.net/tuba.htm The catalog of the southern sky, Coelum Australe Stelliferum, by French astronomer Abbé Nicolas-Louis de Lacaille (1713-1762), was the first to dissect Argo Navis into more manageable pieces. The ship itself became Puppis, the Stern (or Poop Deck); Vela, the Sails; Carina, the Keel; and Pyxis, the Ship's Compass. Two creatures were also drawn as belonging to Argo Navis: Columba, the Dove, and Volans, the Flying Fish. For dwellers of the northern hemisphere, Puppis is the most familiar part of Argo Navis. It lies east of Canis Major, in an area notably absent of any bright stars. Although it lacks naked-eye luster, Puppis is rich in deep-sky treasures. Let's start near its northern border, at a close-set pair of very different looking open clusters.

Colleagues, We're just finishing up a noteworthy January. The annual telescope clinic again Club Officers: featured great stuff from Tom Gilbertson, and was well attended by club members. KMVT even showed up and gave us some air time. Robert Mayer, President [email protected] And at the end of the month, the sky has us buzzing. Supernova SN2014J in M82 is 208-312-1203 believed to be one of the closest observed supernovae since the 1987. The e-mail has been filled with chatter over the discovery, and some members have already Jim Hoggatt, Vice President overcome the weather inversion to get a look at the development -- including one [email protected] member who braved the cold of the City of Rocks. We look forward to hearing from 208-420-7690 their reports as February progresses. Gary Leavitt, Secretary As for this month, it's a case of saying, "it's about time." That is, it's about time for [email protected] the club to check out the new equipment at the Faulkner Planetarium. With that in 208-731-7476 mind, our regular MVAS meeting for February will be at the planetarium. The show starts at 7 p.m., and costs $6 for adults. This is the second straight year the club has Jim Tubbs, Treasurer / ALCOR made it a point to visit the planetarium, and this year, we'll be seeing the new shot, [email protected] "The Astronaut," as well as a Live Sky tour.

Pomůcky: Divadelní kukátko, astronomické dalekohledy o průměru objektivu 2 až 4 palce (54mm až 108mm). Mapa: Richard Schurig: „Tabulae caelestes...“ (nyní asi za osm korun). Zkratky: AR = arcus rektascense, D = dekli­ nace. Vzd. = vzdálenost (družek při dvojhvězdách); vel. = hvězdná velikost čili zdánlivá světlost hvě­ zdy, kterak se našemu oku jeví; p. = posiční úhel. Tabulku posičního úhlu si narýsujeme pomoci papí­ rového úhloměru takto: Kružnici rozdělíme svislou a vodorovnou čarou. Tím vzniklé čtyři body ozna­ číme pro pozorování astronomickým dalekohledem: dole sever (0°), nahoře jih (180°), v právo západ (90') a v levo východ (27o“).

Hvězdy cickumpolární a z části cirkumpolární. Velký Vůz, latinsky Ursa m ajor (Velký Med­ věd, Medvědice). Zmínka o tomto souhvězdí vy­ skytuje sp již u starých Indů, u Řeků, ba i v knize Jobově.

    The COLOUR of CREATION observing and astrophotography targets “at a glance” guide. (Naked eye, binoculars, small and “monster” scopes) Dear fellow amateur astronomer. Please note - this is a work in progress – compiled from several sources - and undoubtedly WILL contain inaccuracies. It would therefor be HIGHLY appreciated if readers would be so kind as to forward ANY corrections and/ or additions (as the document is still obviously incomplete) to: [email protected]. The document will be updated/ revised/ expanded* on a regular basis, replacing the existing document on the ASSA Pretoria website, as well as on the website: coloursofcreation.co.za . This is by no means intended to be a complete nor an exhaustive listing, but rather an “at a glance guide” (2nd column), that will hopefully assist in choosing or eliminating certain objects in a specific constellation for further research, to determine suitability for observation or astrophotography.

  • Binocular Universe: More Poop
    Binocular Universe: More Poop February 2014 Phil Harrington ebruary may be the shortest month of the year, but its sky is long on mid- winter binocular treasures. We all know many favorite objects, like the Orion FNebula and the Pleiades. But rather than rehash these, let's break some unfamiliar ground in the southern sky and enjoy some lesser known gems that lie within the faint constellation of Puppis, the Poopdeck of the fabled ship Argo Navis. Above: Winter star map from Star Watch by Phil Harrington. Above: Finder chart for this month's Binocular Universe. Chart adapted from Touring the Universe through Binoculars Atlas (TUBA), www.philharrington.net/tuba.htm Back in March 2012, this column surveyed some of what Puppis has to offer, including the striking open clusters M46, M47, and M93. This month, we return to the scene to visit some objects to their east. For those of us in mid-northern latitudes, the targets this month are going to be a challenge. You’ll need a good view to the south-southwest and get outside right as evening twilight ends. But you are viewing from south of about 30 degrees north latitude, these objects should all be fairly easy to identify. We begin with NGC 2451, a striking, but often ignored, open cluster. Thirty or so stars are within range of 50-mm binoculars, with the remainder creating a vague background shimmer. Highlighting the scene is c Puppis, the cluster's brightest star. This red beacon stands out well amid a bevy of blue-white stellar jewels.
