BOX 1505 Second Vice President: Riyad Matti [email protected] WARREN, MICHIGAN 48090-1505 Treasurer: Dale Partin [email protected] Secretary: Dale Thieme [email protected] Publications: Debra Chaffins [email protected] http://www.warrenastro.org Outreach: Bob Berta [email protected] Entire Board [email protected] The President’s Field of View Blinky Lights It is better to light one candle than to curse the darkness. But if you are an astronomer, you’d better have a red filter on that candle. I’ve given a couple presentations at club meetings in past years about astronomy gadgets, but my favorite of those gadgets are my red Blinky lights. They may not keep me from cursing the darkness, but they do keep me from cursing when I trip on the legs of my telescope tripod in the dark. Blinky lights are a set of three battery-operated LED lights, each about 1”x2”x ½”. One attaches by keychain to the bottom of each of my three tripod legs. Each contains two AA batteries. Running them for several hours each time I am out observing, the first set of original batteries lasted me five years. I bought my Blinky lights from scopestuff.com, a great source for all sorts of astronomy gadgets. http://www.scopestuff.com/ss_blnk.htm Besides bumping into my tripod legs, when I am under very dark skies I sometimes bump into the legs or sides of my tables and chairs. To solve this problem, I have put 1”x1” squares of glow tape onto each leg and each table corner. When exposed to just an hour of sunlight while I am setting up my gear around sunset, these tapes glow dimly for the whole rest of the night. The tape I use is “Long Life Photoluminescent Tape” from identi-tape.com. But if you just want a small quantity instead of a whole roll, WAS members can buy it at $2 per foot from our club supplies from Jonathan Kade at a WAS meeting. So quit cursing and start blinking or glowing. --Jon 2 Celestron CGE-PRO ultra heavy duty tripod with 3” legs. Unused in new condition.

(2-2013) Dick Gala (248) 549-5238). e-mail: [email protected] 3 Object of the Month - NGC404: NGC 404 is an elliptical galaxy in the constellation Andromeda and is sometimes referred to as Mirach’s Ghost. This unusual moniker results from the galaxy’s remarkable proximity to the 2nd magnitude star Mirach (beta Andromedae), which is less than 7’ away. As such, it offers a faint ghostly visage reminiscent of its nearby namesake. It is about 4’ in size, has an integrated magnitude of 10.3, and a Hubble Sequence Class of E0, although some sources identify it as an S0 lenticular galaxy. Locating NGC 404 is a trivial matter, as it is incredibly close to a star that is readily visible to the naked eye even under the most light polluted conditions. Making matters even easier is the fact that this star is already familiar to most amateur astronomers as the brighter of the two “pointer stars” used for visually determining the position of the famous Andromeda Galaxy, M31. Despite the ease of locating Mirach’s Ghost, actually viewing it can be a fair amount trickier. The relatively faint glow of this object is often overwhelmed by its much brighter neighbor, and the typical tactics employed by galaxy viewers, such as tapping of the telescope tube and averted vision are less effective than normal. Other approaches may prove more fruitful, however, including the use of higher power to increase the apparent separation between the two objects, use of a narrow field eyepiece to better enable one to place Mirach out of the field of view, or the use of an occulting eyepiece to blot out the portion of the field that contains the star. In larger apertures special methods are rarely necessary, as often NGC 404 is visible with direct vision regardless of the glare imparted by its adjacent partner. At low magnifications, the galaxy appears as a meager smudge of light trailing Mirach. Higher power reveals that the Ghost is more than a mere optical effect (a bit of stray stellar light dancing across the eyepiece?) but it is instead an object with an appearance more obviously that of an elliptical galaxy. - Chuck Dezelah This column is a recently added feature written with the intention of introducing a new object each month that is visible from Stargate Observatory using a moderate-sized telescope typical of beginner and intermediate level amateur astronomers. In particular, special focus will be given to objects that are not among the common objects with which most observers are already familiar, but instead articles will mainly give attention to “hidden gems” or underappreciated attributes of the night sky. Members are encouraged to join the Warren Astronomical Society Yahoo Group for messages, photo posting and more. Special Notice: Annual WAS Banquet The Warren Astronomical Society Annual Banquet will be on Saturday, Dec. 8th this year, at DeCarlos Banquet and Conference Center in Warren, MI. It is at the NE corner of 10 Mile Road and Mound Road in Warren, MI. Note that it is not on the third Thursday of the month, and there will be no WAS meeting on the third Thursday of December. We are having the banquet on a Saturday in the hope that more people and their spouses will be able to attend. The dinner will be buffet style, and there will be a bar, but alcoholic drinks will be paid for individually. The open bar was eliminated to help keep the cost of the banquet down. The event begins at 6:30 pm and dinner will be served at 7:30 pm. The cost is $35.00 per person. However, there is a discount of $5.00 (or a total of $30.00 per person) if paid by December 3rd at the Cranbrook meeting. The treasurer will accept your payment and reservation at any meeting, beginning immediately. You may pay in cash or by check. If you are bringing a spouse or other guest, please submit their name with your name when you pay. 4 FREE Telescope Meade 230 60mm f/11 with 25mm eyepiece, finder, and fairly good tripod.

  • Binocular Universe: Aurigan Treasures
    Binocular Universe: Aurigan Treasures February 2012 Phil Harrington ead outside this evening and take a look high overhead. If you live in midnorthern latitudes, you will find a lone beacon cresting near the zenith as Hthe sky darkens. That's Capella, the Alpha (α) star of the constellation Auriga the Charioteer. Tracing back to ancient Rome, the name Capella translates as "She-Goat," a reference to the position it holds in the picture of the Charioteer. He is often portrayed as holding a goat and two kids in his arms. Above: Winter star map from Star Watch by Phil Harrington. Finder chart for this month's Binocular Universe, adapted from TUBA, www.philharrington.net/tuba.htm Today, we know that Capella is actually a binary star system lying some 42 light years away. Each of Capella's suns is classified as a type-G yellow star, like our Sun. That means that all three have roughly the same surface temperature, although our yellow dwarf Sun is only about one-tenth as large as either of the Capella giants. There is little hope of spotting the two Capella component stars through even the largest telescopes, since they are only separated by about 60 million miles, less than the distance from the Sun to Venus. The Charioteer’s pentagonal body highlights a wonderful area of the winter sky to scan with binoculars. There, you will find three of the season’s brightest open star clusters as well as an array of lesser known targets. M38, one of Auriga's three Messier open clusters, is centrally positioned within Auriga’s pentagonal body.

Hopefully, everybody has thawed out by now and, maybe, just maybe, that which is in control of the weather will cut us some slack and give us some nice, cloudless and moonless nights without the sub-zero temps so we can go out an enjoy some winter sky viewing or imaging without risking our toes before the dreaded return of daylight saving time—which, unfortunately, is in March. Even though the month went by pretty quickly, we did manage to get in our Winter members observing night on the 7th of February. Our apologies for the conflicting nights listed in the last newsletter, this was mainly due to our trying to outsmart the weather and making changes to the date at the last minute and accidentally running the minutes from the December meeting instead of those for the January meeting.

  • Human Vision and Dark Adaptation
    AN ABSTRACT OF THE THESIS OF Carsten Christof Grellmann for the degree of Honors Baccalaureate of Science in Mechanical Engineering presented on May 22, 2009. Title: Light Pollution and the Limiting Visual Magnitude in Corvallis, Oregon. Abstract approved: Richard Peterson This study sought to ascertain the degree to which the night sky of Corvallis is affected by light pollution by determining the limiting visual magnitude. Defined as the brightness of the dimmest star that can be seen with the averted naked eye, the limiting visual magnitude establishes a quantitative standard by which to judge the quality of the night sky. Using the star count method and predetermined star fields prescribed by the International Meteor Organization, observations were conducted at Kings Boulevard and Van Buren Street, the Valley Library Quad, and Riverfront Park from the months of November to April. For the purposes of comparison, observations were also conducted at Adair County Park, downtown Portland, and Warm Springs in Central Oregon. This study concluded that the skies of Corvallis are moderately affected by light pollution, with limiting magnitudes between +5.85 and +6.27 with an uncertainty of ±0.12 for the three Corvallis sites, as compared to +7.16 at Warm Springs and +5.04 in downtown Portland. Furthermore, examples of light pollution and its effect on the night sky were photographically documented at each site with a Canon Digital Rebel XT camera and an 8-inch Schmidt-Cassegrain telescope. Key Words: Light Pollution, Limiting Visual Magnitude,
