From the President
Lyle Jones
I hope that all the Dads out there
had a good Father’s Day. I know that I did! Any astronomy
presents?
Did anyone look at the sky on the
night of 16th just after sunset? It was so blue and clear!
I
thought about getting a scope out just
to look at the planets and moon but my back yard is “light city” and I
was too tired to go anywhere else!
I guess that we need to lobby for the light pollution bill that is working
its way through Delaware’s legislature
(http://www.wboc.com/Global/story.asp?S=3411246&nav=QEMtaTZA).
Is anyone in the Stargazers willing
to do some lobbying?
I am hoping to get some observing
in July either at Tuckahoe or Spruce Knob. The skies at Spruce
knob are sure impressive! I am really
looking for to southern sky at Spruce Knob during the Mountain
Institute’s Astronomy Camp. By the way,
Dave Wells is taking his grandkids for the week. There may still
be
room for some more grandkids!
For those who may be interested
on July 6th through 10th is the 2nd annual Green Bank Star Quest
(www.greenbankstarquest.org) at
the National Radio Astronomy Observatory in Green Bank, West Virginia.
Besides the dark skies, the trip would
be worth it just to see the radio telescopes! It takes only 6 six
hours
from Dover to get there. There are
plenty of other activities within an hour drive from the Observatory
(Cass train, Pearl Buck house, and caves).
The family will have good time.
The new officers are planning to
get together in early July for planning our up-coming year.
At the
picnic, we spent some time talking about
our activities for next year and got some of your ideas for the
Stargazers. We also talked
about the No-Frills Star Party in September.
South Pacific Solar Eclipse
Cruise
Kent Blackwell
I left home Sunday April 2, 2005
heading for Washington DC to catch a flight to Los Angeles, CA. After a
long
6-hour flight I arrived in L.A. and then
flew another 8 hours to Papeete Tahiti. Although the flight attendants
endeavored
to make the trip as less strenuous as
possible it still was a grueling travel day.
Upon arrival at the airport in Papeete
the officers of the cruise ship m/v Discovery met us to take us to the
ship. This
had been a very long day; in fact I had
now been awake more than 25 hours.
The ship sailed at midnight. Although
I should have gone to bed I stepped outside to stargaze. Wow, Scorpius
was at the zenith. Crux, better known
as The Southern Cross, was half way up in the sky. The Jewel Box cluster,
though
small in my 10x30 binoculars, was nevertheless
pretty. Eta Carinae was a bright naked eye object. I could see many
involved open clusters through the binoculars,
but the real beauty was the nebulosity in this magnificent region. I
gave thought to unpacking the Orion StarBlast
telescope but decided to go to bed instead. After all, I’d have the next
three weeks to view the southern sky.
Surprisingly I awakened at 5:45
am, just in time to watch sunrise over the island of Moorea, Tahiti. The
shark-toothed Mount Rotui and the towering
Mount Tohivea were beautiful. We docked at Cook’s Bay. Moorea is
rumored to have been James Mitchener’s
idealized island Bali Hai. Many people have described it as the most
beautiful place on earth.
Instead of taking an organized tour
of the island, Robert Hitt and I went ashore and rented bicycles. This
gave
a greater opportunity for picture taking;
allowing us to stop and snap pictures as we pleased. We rode the bikes
down
the main road about 2 miles until it became
too hilly to comfortably pedal. The view of the Pacific Ocean from this
tiny
island is difficult to put into words.
Once back on the ship we dined for lunch and sipped champagne as the m/v
Discovery raised anchor and set sail for
Pitcairn Island. It would take three full days to reach Pitcairn.
I set the clock for an early hour
the next morning to watch sunrise. It was a bonus to see both a beautiful
sunrise and the green flash. Later in
the day it was fun chatting with fellow passengers. I’ve seen many of these
people
on previous eclipse cruises, so it was
good seeing them again. The passenger list included everyone from those
who
had never witnessed a solar eclipse (eclipse
virgins) to those who have seen as many as 25! This would be Bob and my
10th total eclipse. I consider total eclipses
those that are truly total, not annular. Some people count annulars, and
some even count partials, as part of their
list of eclipses. That’s cheating, in my opinion.
Dinner that evening was formal.
After an exquisite meal I set up my Orion StarBlast telescope forward on
the
deck, just above the bridge area of the
ship. I must say I was better dressed that night for stargazing than ever
before.
How often does one hunt down deep sky
objects sporting high gloss black shoes and a fancy tuxedo? There I was
crawling on my knees reading star charts
and pointing the telescope skyward in such attire. The sky was absolutely
stunning, but it took awhile just to identify
the constellations. I can now completely sympathize how “lost” beginners
must feel when viewing the unfamiliar
sky for the first time. I quickly learned that The Southern Cross (Crux)
and The
False Cross were good guidepost for finding
one’s way to other constellations. Dozens of passengers glimpsed
through my scope at various objects. After
I set up the StarBlast a friend from San Francisco assembled his “little”
scope, a monstrous 4” Takahashi refractor.
The view of Eta Carinae in his 4” Takahashi fitted with a 31mm Nagler was
indeed better than my StarBlast, but considering
how very ultra portable and comfortable the StarBlast is to observe
through I’m not sure I could see that
great a difference, especially on a ship moving up and down and from side
to side.
If you ever take a telescope aboard a
cruise ship I highly recommend either a StarBlast or an Edmund Astroscan
as the
ideal instrument. In all honesty Rick
Fienberg (editor, Sky & Telescope) and I agreed his new Canon 15x50
stabilized
binoculars were nearly as satisfying as
the telescope. The only downside of such binocular viewing is the lack
of
tripod adaptor on many stabilized binoculars,
and therefore the inability of sharing views of objects with others.
The next few days would be full
days at sea en route to Pitcairn Island. I enjoy days at sea, and these
were
filled with enrichment lectures from the
Sky & Telescope team discussing eclipses and methods of photographing
them. After dinner I once again set up
my telescope on deck but clouds quickly moved in so I retired to my cabin
for the
evening. At 2:30 AM I awakened to find
the sky had cleared beautifully. I had a great time exploring many open
star
clusters in the tiny constellation of
Crux. One of my favorites, besides The Jewell Box is NGC 4609, a neat little
tiny open
cluster lying just northwest of the 5.3
magnitude star HR 4830. At very low power it looked very much like a globular,
but 30x showed individual stars. It’s
a great object. The real showpiece in Crux is The Coalsack, a velvet black
void in
The Milky Way lying east of the stars
Acrux and Mimosa. I pointed it out to several people and explained how
averted
vision helps seeing it. By 3:00 AM I was
the only person stargazing. Something really neat was the fact that the
officer
piloting the ship would warn me when he
saw rain showers ahead on the ship’s radar. I simply moved the little
StarBlast into a sheltered area and waited
for the showers to end. Within minutes the sky was clear again.
The m/v Discovery arrived at Pitcairn
Island at noon a few days later. Pitcairn is the island chosen by the
mutineers of the HMS Bounty in the 1700’s
as their new home. Even today the tiny island only has 45 inhabitants.
The
seas, always treacherous at this island
were unusually rough the day of our arrival so Captain Erik made the decision
that it was too dangerous for us to go
ashore. The only way to get ashore even on calm days in to climb down rope
ladders from the ship into the islander’s
long boats. But today the swells reached 20-30’ as they crashed into the
rocks
ashore. Nevertheless several of the islanders
came out to greet our ship, bringing their souvenirs on board. I had a
nice discussion with Tom Christian, the
great, great, great grandson of Fletcher Christian. Only three cruise ships
per
year visit the people of Pitcairn so it
was a real treat for them to see us. They only have electricity a few hours
per day
so the night sky is as black as anywhere
in the world. There are no inhabited islands for many hundreds of miles.
Oh
how I’d love to have my 25” telescope
on that island. I was told I’d be welcomed at any time. If you wish to
move to
Pitcairn you’re required to live on the
island four years before being accepted by the community. By sunset we
set sail
for Easter Island, a 3-day voyage across
the South Pacific Ocean.
The eclipse was the next day, and
the most important day of the cruise. I’m glad to say Tom & Betty Christian
had been invited by the ship’s staff to
cruise with us to witness the eclipse. The fascinating couple would sail
with us
to Easter Island but would not be able
to return home to Pitcairn until the next ship sails to their island home
in
November!
After a hearty breakfast on Friday
April 8, 2005 Robert Hitt and I set up our telescopes and cameras on the
deck of the m/v Discovery situated about
500 miles from the isolated land mass of Pitcairn Island. The sky was mostly
clear but some puffy white clouds and
a few high cirrus clouds gave us a scare. It wouldn’t take much for one
of those
clouds to completely obscure a total eclipse
lasting only thirty-one seconds. As our ship steamed slowly forward we
actually gained a full second of totality
from our intended position. The reason Captain Erik Bjurstedt moved his
vessel
was that he feared clouds would be more
prevalent in the original location. Our final position at totality was
S 22 37.879
latitude and W 129 39.27 longitude.
First contact occurred at 10:22
AM, as suddenly a tiny bite was taken out of the sun’s disk. I’ve anticipated
this
for a long time and it was hard to believe
the time had finally come to witness this awesome event. As 2nd contact
approached at 11:51 AM everyone became
more excited. Suddenly the moon slipped completely in front of the sun,
revealing a spectacular diamond ring.
It’s been my experience not to waste too much valuable time worrying about
photographing a total eclipse. At totality,
especially one of this short duration, it’s far more important to look
at it
visually. Believe me, you will never witness
anything in nature to match it.
I watched the eclipse through my
Orion 4.5” f/4 StarBlast, and the view was nothing short of astounding.
Those who have seen prominences through
hydrogen alpha filters may take my word for it those views can’t even
come close to the vibrancy and glory of
those marvelous pink prominences visible during a total solar eclipse.
I can
honestly say I have never witnessed a
more beautiful corona or more spectacular prominences than this eclipse.
Surely that’s because the moon was so
much smaller in angular size than it is at longer eclipses. The view was
just
breathtaking. As I viewed the sun in the
StarBlast I simultaneously photographed it with a Canon 20D digital SLR
camera and an 80mm f/6 William Optics
Megrez refractor telescope, all riding piggyback on the main scope. I’d
like to
offer my gracious thanks to friend Steve
Hamilton for lending me this superb instrument. I never took my eye away
from the 25x image in the StarBlast telescope,
so could only hope the camera caught at least a fraction of what I saw
visually.
Viewing and photographing this eclipse
was one of them most challenging I have ever undertaken because the swells
in the Pacific Ocean reached nearly 10-12’,
with very high wind gusts, and totality only lasted 32 seconds. Even at
25x
the sun would, at times, drift completely
out of the field of view, return to the center and then drift out the opposite
side. You have to learn to snap a picture
on one of these “returns” to be even moderately successful.
The next port was Easter Island,
truly the most remote place in the world. The nearest inhabited island
is tiny
Pitcairn, over 1200 miles to the west.
Easter Island is 2,300 miles from Santiago and, in the other direction
2500 miles
from Tahiti. To its inhabitants it has
always been the center of the world, a fact reflected in its name, Te Pito
o Te Henua,
meaning “navel of the world”, in the belief
that they were the only inhabitants. Easter Island is most famous for its
Moai
statues. The exact number of Moai is unknown
because many lie buried in piles of rubble or beneath the soil at the
stature quarry; the estimates vary from
800 to 1,000 and range in size from 12’ to 30’ tall.
I explored Easter Island two days,
traveling over most of its 18x11-mile area quite thoroughly. Robert Hitt
and
I also explored the very small town center,
stumbling upon a local school. We were invited onto the school grounds
where we promptly handed out solar eclipse
stickers to the kids. I took a photograph of them in a group and upon
displaying their picture the eager kids
stormed me as they saw themselves on the postage stamp size monitor screen
of my camera! We then walked from the
school to the Easter Island Museum situated on a beautiful parcel of land
overlooking the South Pacific where gigantic
waves crash over the rocky shore below.
After these wonderful days it was
time to leave Easter Island. Five days at sea were required for the m/v
Discovery ship to reach the next port
of call, Pisco, Peru. The first night at sea the sky was completely cloudy.
To tell the
truth I was a bit relieved because I needed
to get a good night’s rest. After a wonderfully elegant dinner aboard the
ship I enjoyed a live variety show before
retiring for the evening.
I spent a large part of the days
at sea reviewing different sky maps to determine the most interesting
southern sky objects to view. That wasn’t
as easy as it sounds because I had to only select objects visible in the
relatively small 4.5” aperture of the
Orion StarBlast telescope and objects that would be viewed under the most
challenging conditions imaginable. First,
forget using any printed star maps. I learned that lesson the first night
stepping out on the forward deck of the
ship. The winds howled at 45-55 mph. Immediately, a huge gust of wind
grabbed the David Chandler Southern Hemisphere
Planisphere from my hands and tossed it overboard. I found it best
to use a laptop computer, making certain
to secure the red filter over the screen. Another obstacle was the ship’s
motion. Some nights the sea swells exceeded
30 feet! Imagine the difficulty trying to identify unknown objects and
watching as they drift wildly in and out
of the field of view. By the time I would familiarize myself with the sky
the laptop
battery would die. Those who know me can
only imagine my impatience and frustration. At one point I decided to take
an Orion UltraBlock filter out of my pocket
and put it in a more secure place. As soon as I did the wind grabbed it.
I
watched as it slid under the secured locked
area on deck labeled, “Ship’s Bridge, No Admittance”. Well, no admittance
except for Kent Blackwell looking for
his $80 filter. I hoped no one would step outside the bridge to find me
crawling
around on my hands and knees with a red
flashlight scrutinizing the bridge floor looking for the filter. Within
a few
minutes the filter was found and tucked
away safely. That night didn’t go un-rewarded because I saw several beautiful
open and globular clusters as well as
The Etched Hourglass Planetary Nebula and The Blue Planetary Nebula. I
may
never get a chance to see these objects
again.
Our third day at sea Rick Feinberg
of Sky & Telescope offered an interesting lecture, The Eclipse Revisited.
Rick collected some of the passengers’
pictures of the eclipse. One of the most interesting was a series of pictures
taken by Miloslav Druckmuller. Miloslav
highly processed thirty-one images he took during the eclipse to produce
an
unbelievable montage image. His MMV project
(Mathematical Methods Of Visualization Of Solar Corona) is to develop
new mathematical methods to make the processing
of corona images more effective, especially the highly precise
registration, and to visualize coronal
structures by means of adaptive filters, which are inspired by human vision.
Mr.
Feinberg also showed Robert Hitt’s eclipse
video titled, South Pacific Total Solar Eclipse. Robert put the production
together using digital still images he
and I had captured during the eclipse and am proud to say it was a big
hit at the
finale of the lecture.
I had a number of objects selected
to view but unfortunately clouds moved in for the duration of two days
and nights. Too bad, because the first
ten days of the cruise the weather was clear each day and night.
The next port of call was Pisco,
Peru, famous for it’s fine wines. Pisco has a population of 250,000 but
the
economy is very poor. The only place in
the world I have seen such poverty is Honduras. Most residents don’t have
electricity and live in little more than
houses made of mud and sticks. These are truly desperate souls, but everyone
seemed quite content. I couldn’t help
but think how extravagant we live compared to these people.
At the last minute we were able
to sign up for a long sold out tour to see the Nazca Lines. The exact reason
for
the ancient people etching these lines
into the desert remains a mystery to this day. Our guide suggested the
lines
represented an astronomical calendar.
Many people have their own ideas, some even believing aliens were
responsible!
Nasca Peru is a three-hour bus trip
across the desert from where the ship docked, but part of that duration
allowed for a stop to a museum. Of particular
interest was seeing mummies dating back to 7,000 BC. They’re very well
preserved because of the arid desert climate.
Upon arriving at the small privately
owned Nazca Airport I contemplated whether or not to fly in the Cessna
206 5-seater airplane. Before I knew it
I was pushed into a craft smaller than my station wagon and five of us
immediately taxied off the small dirt
runway. Each person was handed a barf bag but the adrenalin was running
too
high for me to get scared or sick. The
plane flew over one of the many markings with its port wing pointing straight
down for those passengers to get a good
view. Then the pilot circled, tipping the starboard wing down to benefit
the
passengers seated on that side. This went
on for enough time for us to see all the desert markings. Within about
40
minutes we were back on the ground again.
Kent fell to his knees and kissed the ground. That, dear friends, was surely
an experience I shall never forget. If
you ever have the opportunity by all means do it.
The next day was spending cruising
the South Pacific from Pisco to Lima, Peru. Lima, a city of nearly 9 million
inhabitants is a sprawling and beautiful
city. I stayed in the Miraflores region of the city near the beaches. During
the
last few years tourist have made Mirflores
the most visited district of the city, not just for the well-known shops,
cinemas and theaters but galleries that
offer classic and avant-garde exhibitions as well.
Despite being a desert city, Lima
is also humid, yet only receives 2-3mm of rain annually! Lima residents
refer to the gray skies as “donkey belly
gray”. It would not be an ideal city for amateur astronomers because I’m
told
they rarely see the stars at night because
of the thick haze. I spent two days in this exciting city before returning
on a
long flight home.
The three week trip was one of the
most exciting eclipse expeditions I have ever experienced. It was
certainly a total eclipse seen by very
few since it was not visible from any land mass on Earth. Only three ships
on the
expedition witnessed it, a total estimated
at 1500 people. That made it even more special for each of us. The next
total
solar eclipse will be of nearly 4 minutes
duration, and far more accessible than this one. I’ll be somewhere along
the
centerline, ready, once again, to experience
the grandest spectacle nature has to offer.

Observing Notes
Kent Blackwell
NGC 3077 and two close double stars
The other night I stumbled on a pretty
little pair of double stars. These are easy to find because these
bright stars are less than 10' from the
galaxy NGC 3077 in UMa, and therefore in the same field of view even
at the highest power.
NGC 3077 Galaxy Magnitude
10.6 10h 03m +68 44' UMa HD 86677 Double star Mag
7.9 & 10.5, separation
3.3" UMa. I could see black
space between the components in my 10" f/4.7. HD 85458 Double
star
Magnitude 8.5 & 9.41, separation 2.12"
UMa. More difficult than HD 86677 but I could still split it with the
10".
Viewing the Great Red Spot
(Thursday night 6/9/2005 )
Well, dear folks, I hope you got out your
telescopes in the brief clearing this particular evening. It was
public ShowTime at the Chesapeake Planetarium
in Chesapeake, VA (near Norfolk/Virginia Beach, VA).
Steve Hamilton (of BBAA Astronomy Club)
and I watched as clouds moved in just as the public arrived for
the show. But 8:15 the sky cleared so
we set up the planetarium's 33-year old Celestron C-14 and aimed it
toward Jupiter. I have NEVER seen the
planet look so awesome. Steve will concur; detail was visible even
within the Great Red Spot itself. Absolutely
10 out of 10 seeing tonight. Just spectacular! I'm was
impressed. Hope you seeing in MD &
DE was equally wonderful. Sometimes, being near the water as we are
in Tidewater, the seeing is sub-arc second
and tonight was one of those nights.
M 13
The sky was clear last night (6/13) but
the moon occupied the sky most of the evening. I'd like to draw
your atttention to M 13. The next time
you're viewing it (aka NGC 6210) notice the galaxy NGC 6207, only
27'
to the NW and in the same field of view
at moderate power. I managed to see it very faintly with a TeleVue
76mm refractor at 80x, even in the midst
of city lights and first quarter moon. Big scope owners will note it
has a very bright core. Actually that's
a faint foreground star and not the core of the galaxy.
The Solar system in July:
Pj Riley
The nights are getting longer (slowly),
but the temps are still climbing. Everyone is hiding indoors in the
AC, but the nights are the coolest part
of the day, so go out and exercise your glass. Watch out for those
vampire skeeters !
The planets:
Moon: The full moon on the 21st is the
largest in 2005 ! Why? Because the moon is at perigee
the same day.
Go out and look, it might look close enough
to touch.
Mercury is 0.9 deg. N of the Beehive (M44)
on the 3rd. On the next night, it’s Venus’ turn to be close to the
Beehive (0.06 deg. N). These two
planets will be in conjuction on the 7th. On the 8th, the thin
crescent moon
will join these two in the sky.
Mars rises after midnight, reaching ‘bout
30 deg high before morning twilight.
Jupiter is in Virgo, but hurry out to
observe, because it sets around 11pm.
Saturn is in conjunction this month on
the 23rd with the Sun! That kinda rules out any ring watching this
month.
Pluto is out there near Xi Serpentis,
but you need a really big glass.
Perseid Meteor Shower Watch
Have you ever had an all night shower
? Join us for the Perseid meteor shower August 11/12. No
equipment necessary. Details will
be in the August newsletter.
Eclipse Cruise
There are cruises scheduled for the March
2006 eclipse. One 7-day cruise is on the
