Meteor Cruise by Joe Morris
Chuck Harrison and I left the St. Michaels Maritime Museum dock on
the Mister Jim, a 50 ft. yacht, at 8PM Tuesday, May 6th with about
15 observers aboard. Amazingly, there was a break in the cloudy weather about one hour before
departure and it stayed clear during the two hours or so that we were out.
Boats are not the greatest way to observe because of the necessary
lights and because of the frequent course changes, that are disorienting. The green laser pointers are a "must have" for such a session.
As darkness fell, the nearly 1/4 moon and nearby Jupiter stood out. We had several questions about the origin of periodic meteor
showers and about Eta Aquarids in particular. Constellations such as Leo the Lion, Corvus the Crow, the Big Dipper,
and Bootes were pointed out. Observers quickly learned to use averted vision to help see the dim things. After coming ashore, we adjourned to a conference room where I did
a powerpoint presentation of basic visual astronomy and Chuck demoed
his refractor and reflecting telescopes. Things broke up around 11PM
and I think a good time was had by all. Below is the ad that the Museum had for the cruise.

May 6 - Tuesday, 8-11:30 pm
Meteor Observation Cruise
Conditions are ideal this year to view the Eta Aquarids meteor shower.
Join Delmarva Star Gazers representatives while raising your eyes to the
mariner's night scene to observe this annual celestial event. The fast
and often bright meteors leave glowing, flickering flames of light as small
particles of matter traveling through space enter Earth's atmosphere.
The entire family will enjoy star-gazing from Mister Jim.

Program- Protecting yourTelescope and Accessories
Protecting your telescope and accessories includes protection from
moisture, dirt, excessive heat and cold, bumps, and improper cleaning.
First, there is moisture. It is inevitable that your scope and accessories
will get wet if you use them. We are on Delmarva – between two bays and subject to changing
weather. Most damage is done after the viewing session. You
come home late and are tired – you go to work in the morning and forget
to put your equipment where it can dry. Or you bring your cold equipment indoors to a HEATED room and
condensation forms in the internals of the equipment. Schmidt-cass
scopes and electronics are damaged most by this scenario. Bottom
line, put your equipment in a place where air can circulate around it and
where there will be no sudden changes in temps – especially cold to hot.
Remember what happens to a cold soda taken from the fridge on a hot day
– Condensation! Dirt and grime collect on our equipment when there are dusty conditions
on the field, when we allow drinks and food near the equipment, and when
we allow star gazers to touch surfaces with oily/sweaty/dirty hands.
A roll of paper towels for personal hygiene is a welcome addition to the tool bag. Do not
allow a gazer to hold a drink in one hand while observing – prevent spills
and goo on your scope. Use covers to prevent the collection of dust
and other foreign matter. An occasional vacuuming of storage cases and washing of fabric covers
will help prevent crud buildup on the equipment.
Foam rubber is great for preventing bumps to your equipment but it
will collect moisture like a sponge on those dewy nights. Make sure
it has plenty of time to dry before you close the lid on it and your precious
equipment. If you store your scope in the garage take precautions.
There should be no lead-acid batteries, gasoline cans, or lawn mowers close
to the scope. Open the garage door before you start your car to prevent
exhaust gases accumulating (this is a good idea even if you don’t have
a scope in the garage). Invest in a cover to prevent the usual pollen,
dust, and other garage dwellers from collecting in your equipment.
On the observing field please caution your fellow star gazers to avoid
starting their auto engines to “warm up”. It is dangerous for humans
to go to sleep in an idling car. The exhaust collects on the observing
field and gasses those still observing plus it puts a heavy layer of auto
exhaust/moisture on every surface in the area -–including your optics!
A few words about cleaning. Less is better than more. Cotton
is softer than paper and manmade fibers (even though “microfiber” feels
extremely soft because of the diameter/denier of the fiber it is still
a very hard material – my opinion is the tiny hard fibers just make smaller
scratches…), distilled water and soap are better than spigot water and
alcohol, (rubbing alcohol actually has oils in it). Eyepieces should
be cleaned with a damp Q-tip and dried with a clean Q-tip. Never
pour cleaner onto the eyepiece – it will run down the edge of the lens
and collect between the lenses! And use real Q-tips…some store brands
don’t have 100% cotton and some don’t have as much cotton as Q-tips.
Most of this is common sense – prevention is better than the cure but
if you must “cure” please do it infrequently and avoid harsh chemicals
and fibers.
Good luck…
From the President’s Desk....
May 7, 2003 Delmarva Star Gaze IX is over and history. For four
nights and five days amateur astronomers gathered in Tuckahoe State Park
and enjoyed the best of our hobby. We enjoyed beautiful days, a Park
in full springtime bloom, the company of each other, an abundance of food
and drink, and occasionally some skies that unveiled their treasures for
our viewing pleasure through instruments that were only dreams for us a
few years ago. We are very fortunate to have had the opportunity
to participate in an event that allows us to come together and experience
the pleasures of amateur astronomy.
I sat in the pavilion and watched families picnicking together, watched
children running and playing in a non-threatening country setting, and
listened to Nature’s forest critters’ symphony. I observed old friends
talking and new friendships being cultivated, memories being made…all of
this would not have been possible except for Delmarva Star Gazers’ efforts.
Delmarva Star Gazers, you did well. I am proud of your efforts and success. I want to thank each Star Gazer who volunteered their time, skills,
and good will, to ensure this event’s huge success. Without your
outstanding effort, Star Gaze IX would have been a less satisfying experience.
Thanks again – I can hardly wait for No-Frills.
We, Delmarva Star Gazers, have completed our 10th year! As we
begin the 11th we look forward to better times, better instruments, increased
opportunities for learning more about our world and sharing our knowledge
with every person who demonstrates a will to learn and become a part of
amateur astronomy. I often hear comments from newcomers that ours
is a friendly environment. Let’s strive to keep it that way…let’s
continue to do the right things the best we can and respect each other while doing the right things the best we can.
Last night we accepted nominations for officers for 2003-2004.
The nominations were: for secretary, Keith Lohmeyer; for treasurer, Kathy
Sheldon, for vice president, Lyle Jones, and for president, Don Surles.
Since there were no other nominations, these people will be your officers
for 2003-2004. Congratulations! These folks have demonstrated
their competence and dedication to Delmarva Star gazers for years. Please support
them as they carry out the day-to-day duties of their office.
It is time to finalize our goals for 2003-2004. We are scheduled
to meet at Kathy and Frank Sheldon’s home June 8 to review Delmarva Star
Gaze IX and I will present an outline of proposed 2003-2004 activities
for consideration. Please email or call if you have suggestions for
“go-do’s” in the coming year.
We will begin final polishing of our 22 inch mirror May 17. If
you would like to participate please email or phone – my phone number is
302-653-9445. Here is the proposed schedule for polishing:
22” MIRROR POLISHING AND FIGURING
Proposal: Polish during full moon weeknds; Saturday or Sunday afternoons
1:00 thru 6:00 or until pizza or liquids.
Where: My garage or basement depending on temperature

This should be a fun time for all and an opportunity for us to complete
a large mirror and ultimately a large club scope for the Star Gazers to
be proud of.
Well, observing certainly has been a bust since Christmas – I continue
asking myself how much longer this streak of clouds will continue. I guess Mother Nature is filling the rain bucket
so we won’t have that drought thing to contend with this summer.
But, we shouldn’t lose the desire to observe – “star gazing” is the reason
we exist. So, keep your Naglers packed and your scope gassed up for
those occasional nights when the skies will open to reveal it’s treasures
to those willing to look. This is just a period of changing weather in a changing of the seasons –
better weather is on the way.
As warmer weather settles in with accompanying mosquitoes you should
consider adding a mosquito repellent to your normal gear. Mosquitoes
are carriers of West Nile Virus – and per Ben Franklin, “An ounce of prevention
is worth a pound of cure”. The Tuckahoe mosquito may have had access
to West Nile Virus. Let’s try to discourage his attendance at our
star gazing functions.
Stay tuned for more Star Gazer news.
