At the December Meeting......
Don Surles brought the meeting to order at 7:15 with 25 members and guests attending.

New Member: Marc Henderson,Newark, DE

Outreach Opportunities
Prime Hook Wildlife Refuge-   Don Surles gave a  presentation to this group on December 9 at 7:00 p.m. with 12 people attending.
Montessori School-   On November 9th, Keith Lohmeyer, Lynn King (DAS) and Jerry Truitt did a presentation for United Way at the Montessori School.
Astronomy at the Library   Jerry Truitt, along with Keith Lohmeyer, James Morgan, and Bill McKibben presented a program at the Elkton
Central  Library on November 19th.  A letter from a student and a note from the teachers were received.
Willingboro Astronomical Society  by James Morgan
On Saturday November 6th, Jerry Truitt, Leonard White, Bill McKibben and several people from the Delaware  Astronomical Society joined with the members
of the Willingboro Astronomical Society to do some observing. The location was Fort Mott in New Jersey, just across the Delaware Memorial
Bridge.  This group is very much like our Delmarva Stargazers in both activities and temperment.   They are a fine group and it was a pleasure to meet
and join them in observing.  This was the first time I ever was at an observing event where the group ordered pizza delivered right to the observing field. A great
time was had by all. James T. Morgan.

 NASA Update
Jerry Truitt gave a power point presentation updating some of the Nasa projects .
  (1) The first image was taken with the Cassini Space Craft Wide Angle Camera on October 27, 2004 at a distance of 392000 miles from Saturn. This image shows the unlit side of the B rings.
 (2) The 2nd image was taken with the Cassini Space Craft Narrow  Angle Camera on October 29 at a distance from Saturn of 523000 miles.    It shows Saturn’s
inner C ring in an area 46000 miles from Saturn.  In the center of this area lies the dark Columbo Gap which houses the bright narrow Columbo Ringlet  in resonance with the moon Titan.
  (3) The 3rd image was taken on October 29 at a distance from Saturn of 509000 miles. Here the Cassini Narrow Angle Camera caught the sunlit side of the
outer B ring. Other objects involved were the Huygens Gap, the Huygens Ringlet  and the Moon Mimas.
 (4) The  4th image is a view of the potato shaped  moon Prometheus (63 miles across) ,interacting gravitationally with the multistranded F ring.
The Cassini Huygens portion of the power point ended with the December 3th Flyby of Saturn’s Moon Titan.
Also included in the NASA update were images taken on November 19th, when Rover Spirit’s Microscopic Imager took numerous photomicrographs
of 3 cm square samples of martian soil.

From the President’s Desk....
So, did Santa unload his sleigh at your house?  Did you get boxes and boxes of telescopes, eyepieces, computer-scope-camera connections and
combinations...maybe even some dark sky for wrapping paper?  Throw in a comet or two and we have the makings of a real Christmas for AA’s.
I hope you got a garage full of AA goodies because Santa and the postman have conspired and sent a sleigh full of bills to my mailbox.                                         Just be ready to share your new toys when we are observing together and I will share some of the bills!!!

Speaking of Comets!  There is a beauty in Orion’s portion of the sky at this time.  In the coming weeks Comet Macholtz will leave Orion, travel north
across the top of our sky, and increase in brightness as it travels north.  Log onto Sky & Tel to get the trajectory coordinates and plot them on your star charts.
This comet bears watching because it could become a real beauty.  Today it is a large, bright fuzz ball easily found in binoculars.  By the new moon in January
it should be much brighter.  Put Comet Observing on your schedule.

Was it cold enuf this morning?  My thermometer read 11 degrees F at 8:00 AM and I think the low was around 6 degrees F.   BRRRRR!  As the cold artic wind roared around our house this morning and I pulled the covers a little closer, I thought, “This is a very good morning to be on vacation”.  Then the new baby cat pounced and pounced again so I had to get up.  Such is life.

Our January meeting promises to be a great one.  Dave Wells will cover Home Observatories.  Astronomical photography will be revealed by Norman Todd (CCD cameras), Steve Long (digital cameras), and Don Surles (antique film cameras).  Greg Lee will tell us about Johannes Kepler and his Rudolphine Tables.  Jerry Truitt will update us on the influence of the Internet’s WWW on amateur astronomy.  And Keith Lohmeyer will tell us all about the January night sky.  So, put the meeting
on your calendar and join us for hot coffee and left over holiday cookies Tuesday night, January 4, 2005.

Yes, you have seen the following information before and it is still valid.  Orion is the Jewel of the Winter Sky – don’t postpone looking at it.  From 2003:
‘this is the season for Orion watchers.  The great constellation is “on the meridian” just after sunset during January and early February.  A word of caution: Observe now and observe often – the brilliance of Orion’s jewels will diminish as it heads westward during late winter and early spring.  Aperture and power complement
Orion’s wonders; use your largest scope and increase the power to the max; you  will not be disappointed with the Orion family.  But again, please do not postpone
your viewing – Orion’s beauty diminishes rapidly after the next few weeks.”

How about some New Year’s Amateur Astronomy Resolutions?  Is this the year you will make your very own telescope?  How about trying your hand at photography? Maybe grind and polish a mirror?  Or connect a computer to your scope?  Or add a day of observing to your very busy schedule?  How about promoting amateur astronomy in your circle of friends?  This is the year you can make a difference. All you have to do is make an effort and I guarantee you will be surprised at the results.

Please take every opportunity to make the most of these long, cold, clear, and transparent winter nights.  They can offer some of the best observing of the year.
All you have to do is bundle up, protect your sensitive twinkie-toed feet, do something similar to protect your balding head, and of course you will need some
hand protection; after all this, if you can still move, move toward the scope and do some serious viewing.  We are all waiting for you to recap your experiences on
our yahoogroups.
Enuf for now; see you in January.
Don…

Solar System in January
As with December, most of the happening stuff will be in the morning hours.  All of  the major planets except Saturn will be morning stars in January and even then,
Saturn will be visible into the wee hours. Mercury and Venus as morning stars on January 7th will both be low in the SSE and less than one degree apart.
 Mars will be nearby to the west and just above Antares in Scorpius as January begins but will retrograde 16 degrees by month’s end.  Although Jupiter
doesn’t rise until midnight, the best viewing is at its highest point in the morning twilight.   Saturn is at opposition on Jan. 13th, which makes Jan. a good month to view this planet.
The Messiers, M35, M36, M37, and M38 are all good objects to find this month. M36 and M38 are inside Auriga,with M35 and M37 between Auriga and Gemini.  Skip Neptune and Uranus in the eveing as well as Pluto in the morning  this month, as they are too close to the Sun.
January is also the month that the Cassini Huygens module will be inserted via parachute onto  the moon Titan.  While NASA currently seems almost secretive
about the time line involved,  my sources put the module insertion on January 14 at 9:00U.T.                                                                                                    C/2004 Q2 (Machholz) in January at magnitude 4 will pass from Orion to.just  west of the Pleiades where it may be visible to the naked eye or certainly to the Bushnell Voyager discussed below:

BUSHNELL’S VOYAGER 4.5 INCH FAMILY TELESCOPE Model  78-2010

<>Back in November, Jerry Truitt mentioned in the Yahoo pages, a special sale for the Bushnell VOYAGER 4.5 inch Family Telescope.
 Judging by the photo in the ad, it appeared to be a knockoff  of the $199.99 Edmunds Astroscan.   Both scopes are 15 pound Newtonian reflectors
 with roughly 4.5 inch apertures at f4.5 .
 
With an original $330.00 list price, Bushnell’s special sale price  was $99!! 
  
Now I need another telescope like Imelda Marcos needs another pair of shoes but this deal was too good to pass by, especially with no shipping charges.
 
When the scope arrived 5 days later, I was favorably impressed. The Mirror ball rotated as smooth as silk in the heavy aluminum cradle as I slewed
 the optical tube around at <>every conceivable angle. The secondary mirror is permanently mounted to the flat cover glass, eliminating the need for
 a spider or any other aperture obstruction.   Even though the scope was factory collimated, it was reassuring to see 3 collimating
screws on the secondary mirror mount (just in case).  The flat glass cover is a mixed blessing, since it probably guarantees dewing problems. 


In actual use, the Voyager must be placed on a stable horizontal vibration free surface  I started with some daytime terrestrial viewing .  My scope came with two 1.25 inch Plossl eyepieces having focal lengths of 27mm and 5mm. Since the objective (mirror) has a focal length of 500mm, this gave me magnifications of 19 power and 100 power respectively. The 27mm eyepiece had wonderful eye relief and could be used with or without eyeglasses. The 5 mm eyepiece had a bb sized aperture and because of the low eye relief, could not be used (by me) wearing eyeglasses.  The 5mm. eyepiece was reminiscent of eyepieces of the so-called department store scopes.  By using my own eyepieces however, I eventually wound up with a satisfactory range of useable magnifications from 20 to 200 power.  The latter was attained with a single eyepiece, the 2.5mm Vixen (lanthanum).   The scope came with no finder, nor do I think  it needs one. A wide angle 35mm eyepiece can find anything,  After finding your target, center it and gently remove the eyepiece.... Then the rock solid vibration free Voyager permits you to drop in your viewing eyepiece without losing your target.
 
One of my first goals with this telescope will be to check it out on my favorite celestial objects to wit: the Moon, the Pleiades, the Lyra Ring Nebula, M13, the Great Orion Nebula, and the double star Alberio in Cygnus.
 
In conclusion, I feel this scope has a real niche for beginners (and everyone else for that matter).
.  
 For myself, I’m certain my viewing time will double in the coming year. With the lousy weather we’ve had going on for 3 years, I hardly ever dragged out
my 2 big guns: a 12.5 inch Dob  and a 6 inch refractor. 
 
The 4.5 inch Voyager is easier to use for star hopping  than my 20X80 binoculars!  At 15 pounds with its own  carrying strap, easy transport is guaranteed.  Yeah, stargazing is going to be fun again. 
 Clear Skies,  Frank Sheldon

Moondark for January: Deep Night Weekends for 2005

For the darkest skies, unspoiled by moonlight, observers plan around the new moon. Deep night refers to that time between astronomical twilights without the Moon in the sky. Especially favored are the deep nights of Fridays and Saturdays listed in the table below. Most of these are regular monthly observing nights for the Delmarva Star Gazers, and these circumstances are calculated for Tuckahoe State Park, MD, 38° 59' N and 75° 56' W.

All times are local: Eastern Standard Time is 5 hours behind Universal Time; Daylight Saving Time, between 3 April and 30 October 2005, is 4 hours behind. New moons start the year on 10 Jan and gradually advance to the beginning of the months by year's end. In fact, December has two new moons: on the 1st and then on New Year’s Eve. Observing windows match twilight times because (fortunately!) New Moons tend to fall on weekends this year (N.B. moon phases are UT). This table is also available in text format for every day of 2005.

2005 looks promising. As the year opens, we have bright Comet Machholz in the northern sky, and the Huygens probe reaches Saturn’s moon Titan. Throughout the year, there are lunar occultations of Jupiter, Antares and Spica. Mars returns and dominates the sky through year’s end. But why not use these deep nights to re-discover the constellations or complete your Messier list? For a greater challenge try the Caldwell, Herschel, NGC lists, or even the catalogs of hordes of dim, hard to find planetaries and galaxies out there. Our club has experts in all these, and our members will be only too glad to provide encouragement. Participate in the online discussion at the club's Yahoo! site or join us at a monthly meeting, held on the first Tuesday of the month in Smyrna.
