"Are you awake?" I heard Steve ask, as I rolled out
of the over-soft hotel bed I'd been snoozing on.
"Yeah, I'm up. and I'm hungry". It's funny how your

Registration for Winter Star Party

an alarm clock, we were both up right on time for our meeting with the Chagrin
Valley Astronomical Society. But first. dinner!
The CVAS is an amateur astronomy club in Ohio. They have an observatory about
thirty-five miles east of Cleveland. It's located on private property on a
site known as Indian Hill. During the warm months of the year, the CVAS holds
their meetings at the observatory, followed by an observing session. We had
been invited by the club's president, Bob Modic, to attend a meeting and join
in the observing from their dark sky site atop Indian Hill.
I met Bob (pictured at left) through the internet. I had seen his observer
initials and name listed in some of the AAVSO news flashes and had noticed
his observations posted to VSNET. He seemed to be concentrating on cataclysmic
variables so I took the initiative and introduced myself as a fellow AAVSO
member and "CV junkie" in an email message. Bob wrote back and we
started sharing notes on astronomy clubs, variable stars, equipment, weather
and other things. Since Cleveland is only a four hour drive from Detroit,
it was inevitable that the subject of a visit would come up at some point
in our discussions. That's how Steve Greene and I eventually found ourselves
napping in a Days Inn off I-90, east of Cleveland.
Even though the weather looked "iffy" at best, we both decided to
bring our telescopes for the observing session. Steve was planning on a "first
light" session with his newly built 18" Dobsonian, a beautiful handcrafted
instrument. And when I say newly built, I mean the last screws were countersunk
an hour before we left! I had been thinking about cleaning the corrector plate
on my scope for some time, so this was the perfect excuse for me to take the
scope and wedge out of my observatory.
The trip was uneventful and the traffic was light in spite of it being a holiday
weekend. We arrived at Indian Hill around 2PM. The gate was locked so we parked
the van and took a hike up the road to the top of the hill. The first half
of the hike is up a slope about thirty-five feet up. There it levels off and
there is room for cars to park, a pond and a clearing for observing. Another
hike through the trees up a little steeper slope, and you reach the summit
of Indian Hill where the roll-off roof observatory is located.
The building is much larger than our club observatory. I'd guess it is about
20' by 40'. It's divided into two rooms. One half is for storage and houses
their 14" Dob on wheels which can be rolled out the door for observing.
The roll-off half houses the club's 16" Newtonian (pictured at right),
a monster of a scope on an impressive pier. They have an unobstructed view
to the south and east and on a good night you can see sixth magnitude stars
from Indian Hill.
After our brief unguided tour, Steve and I drove back to the freeway, checked
into a room, took a short nap and enjoyed a prime rib dinner at the restaurant
across from the hotel. We arrived back at Indian Hill around 7PM, just as
the club members were arriving. We were greeted by the observatory chairman
and given a tour of the facility. As the roll off roof was opened, a startled
bat began flying around the inside of the building. Coexisting with the local
wildlife is a small price to pay for an observatory far from city lights.
Folding chairs were set up in a clearing next to the building and the meeting
(pictured at left) was held in the open air under the setting sun.
It was interesting to note the similarities between topics of discussion at
their meeting and our meetings. There were reports of the auroral display
of August 12, which coincided with an active display of Perseid meteors. They
talked about their recent decision to distribute their newsletter electronically
to save on postage just as we did at the beginning of this year. They discussed
observing targets for the month and maintenance of the club observatory. I
found the discussion on choice of herbicides to kill the invading poison ivy
particularly interesting. Thankfully, that is a problem we don't have!
As darkness settled in, the meeting was adjourned and we headed down the slope
to the observing field to set up our scopes. There were some openings between
the clouds, but the sky was very hazy and conditions on the ground were getting
wetter and wetter. Fog from the pond nearby settled heavily over our position.
We didn't manage to do any observing but Steve got a chance to talk with many
of the CVAS members who had built and use large Dobs. I had a chance to share
some variable star observing tips and stories with a few of the members. We
gave up and went back to the hotel around midnight.
Even though the observing session was a bust for us, we resolved to try again
some time in the near future. The Cleveland area has the Rock and Roll Hall
of Fame, a science museum, Cleveland Botanical Gardens, a zoo and many other
things to see and do, so we may take the wives next time and make a long weekend
The next morning in the hotel as I awoke Steve asked. "Are you awake?"
"Yeah, and I'm hungry, too". The drive home would only take four
hours, but first...breakfast!
that moon. It's indirect evidence, of course, but no one has been able to
explain the signals makeup any other way. She says the ice layer could be
between 0.5 and six miles thick, with the liquid water beneath, up to four
miles deep. Future NASA spacecraft will be studying Europa with more advanced
magnetic detectors, to verify and enhance her results.
Our software library has grown with the addition of a new program called SATELLITE
TRACKER. It's another tracking program with a special twist. The program will
interface to an LX200 and actually automatically track a chosen satellite.
If your LX200 system can't keep up with the satellite, it will "leapfrog"
to the next part of the sky to let the satellite drift through the field.
This one sounds pretty good. I'd like to see it in operation myself.
Finally got to see Space Cowboys and found that the movie keeps you glued
to your seat. There's a lot of tense action after the cowboys get into orbit.
Before that happens, you might compare the constant griping and complaining
to something that resembles "grumpy old men". It's worth everything
you spend for the show, if you catch a matinee. Five stars, it's not, but
I'd give it four. The ending (last minute or so) is kind of uncalled for,
but I won't tell you about it. It should have stopped with Clint Eastwood
and wife, gazing at the Moon. Tell me what you think after seeing it.
The September computer meeting (9-28) has been moved because Gary Gathen,
our host, will be out of town. The meeting will be at my house, in Roseville,
15674 Flanagan, two blocks west of Groesbeck (M97), two blocks north of Common
Road (12 1/2 mile road) starting at 8:00 pm. Look for the yellow porch light
on the south side of the road, about eight or nine houses from Callahan. Call
me at 810-776-9720 for further information. You can reach Gary at 248-543-3366
for further information about the October meeting. The October computer meeting
will be on the 26th. Gary lives at 21 Elm Park in Pleasant Ridge. Three blocks
south of I-696 and about half a block west of Woodward.

and peasants (people without observing equipment) are welcome! We thank you
all for your participation in years past and it is our hope you will join
us once again in Fun, Food and Stars (weather permitting of course, this is
still Michigan). To all astronomers who wish to assist the peasants in their
enjoyment of this fine science you may contact court Astronomer John Kmiecik
again, thank you all Astronomers. We hope to see you at this year's event.
George Korody adds: All astronomers and general public who will be bring observing
equipment to the Eighth Annual Island Lake Star Party, must arrive early while
there is still parking available at the pavilion parking area. Otherwise,
there will be no place to park with equipment. Additional parking is one and
two miles further down the park roadway. As was done last year, a free shuttle
van service will be provided between the more distant parking areas and the
star party area.

The developer came to the first meeting at Dexter Township Hall with a proposal
to develop a gas station, minimart, car wash and fast food restaurant on the
above described corner. He did not own the property at the time. He was met
with major opposition to this project by the Township residents and many others.
He eventually purchased the property, the Township Planning Commission said
NO to his proposal, he came back with modifications to his proposal, the Planning
Commission still said NO. The developer came back with a new scaled down version
of the proposal to only a gas station and minimart. The most recent meeting
resulted in a postponement to Sept 26 for the final vote. I am short of time,
so I have greatly condensed the above description. This site is next to wetlands
and the Huron River. Its been about two years since the developer first proposed
his complex of structures.
I am searching for all Legislation at the County level, State level and National
level that can be used to oppose this development. Legislation about water
pollution, light pollution, general nuisance laws etc.
Probably our best argument is the potential pollution to the Huron River and
therefore the potential pollution to the water supply of all the downstream
Any and all help to oppose this developer is greatly appreciated, such as
searching for legislation, writing letters to the Planning commission, appeal
letters to the developer, or even incomplete text would be helpful.
I think there is a good chance the Planning Commission will again turn it
down, all of the past arguments are still valid,--- but--- there are two new
Commissioners on the panel.. The developer is planning to file a lawsuit if
the above takes place. If the Township is adequately represented, I believe
the township will win, but we need to do everything we can think of to insure
the victory over the developer.
Low-Price, Highly Ambitious Digital Chip
- per square inch. That, by some measures, is about twice the resolution of
Today, a company founded by one of Silicon Valley's pioneer chip designers,
will announce an image-sensing chip capable of the same resolution as the
Kodak chip, but made using a technique that could be much less expensive.
Executives of the company, Foveon, said they had given a prototype camera
based on their chip to a photographer in Los Angeles, Greg Gorman, who had
used it to make a portrait of a cowboy. In that image, no pixels, or dots,
were visible to the eye, even with the photograph blown up to a size of 8
feet by 4 feet.
Already, digital cameras being sold on the consumer market for less than $1,000
are rivaling 35-millimeter film cameras. Digital images of the clarity achieved
with Foveon chip could begin to challenge even the much more expensive 4-by-5
film cameras made by companies like Hasselblad that are used by professional
photographers for portraiture, advertising and fashion.
"We're headed to flat-out replace the film camera," said Carver
Mead, the founder of Foveon, which is based in Santa Clara, Calif. Mr. Mead,
a pioneer of the chip industry, became a Silicon Valley legend in the 1970's
by helping develop techniques that for the first time enabled chip engineers
to create circuits containing tens of thousands of transistors. Industry analysts
say that the new technologies could affect much more than still cameras. High-resolution
images, if produced in quantities that made the new generation of image-sensing
chips cost only several dollars apiece, could become a staple of cellular
telephones and other hand- held devices and might bring the cost of a consumer
video camera below $100.
And the contest is not only between film and digital sensors, but between
two kinds of chip-making techniques. Foveon's planned announcement, coming
on the heels of Kodak's, suggests a sharpening battle between the two competing
manufacturing technologies at the heart of a billion- dollar market for digital
The Foveon chip is based on a low- cost semiconductor industry technology
known as Complementary Metal-Oxide Semiconductor, or CMOS (pronounced SEE-moss).
The Kodak chip's sensor is based on a more expensive manufacturing technology
known as Charged Coupled Device, or C.C.D. imaging.
C.C.D.'s now dominate the digital- imaging industry, but compared with CMOS
devices, they require production and assembly of several chips and related
components to combine the sensing and computing tasks that can be performed
by a single CMOS chip.
Both companies' achievements have startled industry experts because the new
devices move far beyond the current industry standards for CMOS and for C.C.D.
cameras, which until now have been able to achieve resolutions of 6 million
pixels a square inch. The Foveon and Kodak sensors can pack 16.8 million pixels
into a square inch.
"If you asked someone if this was achievable in either technology two
weeks ago, they would have said it was impossible," said Michael Berger,
an industry analyst at Frost & Sullivan, a market research firm in San
The Foveon announcement is seen as a personal triumph for Mr. Mead, 66, who
is regarded by many executives and engineers as the father of the modern semiconductor
"Carver has tapped into something enormous," said Alexis Gerard,
president of Future Image Inc., a digital-imaging research and consulting
firm in San Mateo, Calif. "When digital imaging and the telecommunications
infrastructure converge, they will enable a shift from a text-based communication
model to an image-based model."
Throughout his career Mr. Mead has explored the idea of duplicating the human
senses, including vision and hearing, by using silicon-based chip technologies.
Several years ago, his earlier work led to the development of a smaller and
more effective hearing aid now sold by Sonic Innovations of Salt Lake City.
Complex chips first became feasible in the 1970's after Mr. Mead, at the time
a professor at the California Institute of Technology, teamed up with a Xerox
computer scientist named Lynn Conway to invent a technique for placing thousands
of transistors on a chip - a technique known as Very Large Scale Integrated
Circuit, or VLSI design.
Today, CMOS-based manufacturing - which is used to carry out VLSI design -
is employed by virtually all microprocessor and memory makers. As a result,
it has become extremely cost-efficient and can yield circuitry with more transistors
and lower power requirements than most competing technologies.
Yet despite their promise, CMOS- based sensors have until now had just a tiny
impact on the overall market for digital imaging because they have been unable
to achieve the resolution and clarity of C.C.D. sensors. The global market
in 1999 for C.C.D. sensors was $959 million, compared with only $14.2 million
for CMOS sensors, according to Frost & Sullivan.
But even before Foveon's latest achievement, CMOS was gaining ground. Not
only have companies including Kodak and Polaroid begun to offer inexpensive,
low-resolution CMOS-based cameras, but telecommunications giants like Nokia
of Finland and NTT DoCoMo of Japan are planning to include inexpensive CMOS
sensors in millions of their next-generation cellular phones.
Foveon's contribution has been to improve the quality of CMOS images by continuing
to put more computer processing power behind the task of capturing the digital
image. The new 16.8 million pixel device has seven active transistors for
each pixel. The benefits include less interference, better focusing and more
precise exposure times. "When the pixels get smarter," Mr. Mead
said, "that translates into better image quality."
Foveon's principal investor and the company's technology partner is National
Semiconductor, a big Silicon Valley chip maker. National Semiconductor's manufacturing
plant in Santa Clara is capable of etching chip circuitry only 0.18 micron
wide - a microscopic fineness that few other chip makers can equal. By contrast,
most current low-cost CMOS sensors are made with circuitry of 0.35 or 0.5
microns, which allows for millions fewer transistors per chip.
National Semiconductor executives said the company was planning to take the
technology that Foveon had developed for the priciest reaches of the professional
photography market and make it economical enough for some new consumer electronics.
"National's interest is not in thousands of cameras a year but in hundreds
of millions of cameras a year," said Brian L. Halla, the company's president
and chief executive. "We could make the world's highest-resolution throwaway
digital camera and sell it for the price of a similar Kodak system."
Foveon officials said they would demonstrate the new 16.8 million pixel sensor
for the first time today. The sensor, which for now captures images in black
and white, has almost 70 million transistors - or about two and a half times
the number of transistors used by a Pentium III microprocessor chip for computers.
Foveon says it expects the new sensor to be on the market within a year.
Currently, Foveon sells a high-end camera using an earlier version of its
sensor that has a resolution of 2048 x 2048 pixels, or 4.19 million in all.
That camera uses three separate sensors and a prism array to separate color
information. But Mr. Halla said the company was also working on a technique
that would permit a single chip to capture precise color information.
Despite the advances now being made, Mr. Mead acknowledged that digital-image
sensors are still a long way from matching the skills of the human eye.
An eye is movable, which enables it to scan various parts of an image and
then allow the brain to compose a single, larger image. The eye is also remarkably
diverse: elements that have high resolution are clustered at the center of
the field of vision, while sensing elements that function well at low light
levels are around the periphery of the eye, giving human vision a great flexibility
of range in varying light conditions that no artificial imaging system can
Mr. Mead said that because of fundamental size limits in the wavelengths of
light, it is unlikely that future digital sensors will gain much additional
resolution. Instead, shrinking semiconductor circuit sizes will make it possible
for companies like Foveon to add more and more intelligence to their digital-imaging
systems, perhaps simulating more of the image-enhancement functions of the
