A little Less Photography

When I began astrophotography in the 80's there were literally just hundreds of astrophotographers in the world.  Thanks to the digital revolution, there are thousands upon thousands, many of which are very good.  Thirty years ago, all we had was film, but even today we still use our eyes to observe.  I must admit that for the last ten years or so astrophotography has held top billing for me. Observing took a back seat as my eyes were mostly held up in guiding images.

I was a keen deep sky observer back in the day. This means I would use optical instruments, primarily telescopes, to tickle out those faint fuzzies in the night sky.  These were various stellar and non-stellar objects such as star clusters, nebulae, galaxies, and planetary nebulae.  Photography has changed, but observing has changed little.

I don't like crowds.  I prefer to work alone and with the tools that I personally like to work with.  The end of the days working with film are all but gone.  I really do not want to join the crowds of digital mavens honing their crafts with the latest gadgets and squirrel cage wheel of innovation.  More and more I just want to observe. I've grown tired of photography.  The stream of Milky Way images have never been greater.  It's time to move on.

My eyes have aged, but they are essentially the same.  Age has also given me the wisdom to see once again that the act of observing as much more precious.  The photograph pales to the direct experience of observing.

Last night I could see what I have been missing.  A pair of binoculars on a tripod and a sweep of the skies made the case for returning to my roots.  The downside is in the sharing.  I may post a photo or two to convey just where I am looking, but the projected images on my retina are solely mine.



Observing - The direct act of communion with the Cosmos

Photography has given me so much pleasure and insight into the Milky Way.  The cake has been iced.

Now it's time to enjoy a slice.

Doubling Down !

In April of 2007 I converted most of my astrophotography efforts to use medium format film.  The acquisition of the Pentax 67 soon brought forth amazing images of the Milky Way as well as night landscapes under the light of the Moon.  The Pentax 67 is a great system and I soon had a lens collection to offer near unlimited flexibility in my compositions of the starry realm.

This past April I came across a deal I could not refuse.  I added a second body and two lenses.  The lenses were duplicates to what I owned, but an idea floated around in my head.  The recent addition of a new german equatorial mount made it possible to configure many possible arrangement of cameras and telescopes.  I purchased the necessary Losmandy plates and gathered an old Televue Ranger to be used as a guide scope.

Two Pentax bodies and matching 105's make a formidable team.  Simultaneously exposing two frames will make lighter duty of combined framed images and mosaics.

I do not believe this has ever been done or if it is workable.  I believe it is.  I have the freedom to use lens pairs or two different focal lengths if desired.  It will make mosaics much easier.

The image below is an example of two frames using the 105mm.  The two frames were exposed  sequentially.  The new mounting and camera configuration will make this a "one shot" effort!

This image was done with two frames using the 165mm f/2.8.  This is another possibility using the two camera setup.

So planning continues.  I will give it a try later in the summer.  Skies darken very late in June and time to shoot is very limited.  I prefer late August to begin film work. Skies darken early enough to get a good session in prior to midnight. 

When the year started I was looking for direction as to where I would go in my efforts.  The digital workflow has made me lazy and I was never 100% happy with the colors and textures.  It appears I will still work with film for some time to come.

There are plenty of digital astrophotographers out there.  They do good work.  This is my story.  I'll tell it a bit differently.

The Full Moon of June!

On Friday morning, my friend John Stetson had imaged the setting Moon on the western horizon right before sunrise.  He had lamented that he would not get the shot that evening as weather was expected to be unsettled.  Sure enough the forecast looked bleak, but the onset of clouds in eastern Maine looked like a close call.

After dinner clouds were drifting in, mainly thick cirrus.  This could actually be a benefit to the shot I was hoping to get.  Clouds often add to the composition.  As Moonrise was approaching I grabbed the camera and tripod and headed down to the pond.  I've done this path a thousand times before.  It's my backyard.

The Moon was just coming up when I got into position.  There was plenty of gaps in the clouds and some drifting in and out of the view.  I took a series of images over a twenty minute span and then headed back as the clouds of mosquitoes had me at my wits end!


Moonrise Over Flanders Pond

I think it worked out well.  The Full Moon of June is also known as the Full Strawberry Moon by tradition.  This is also a "micromoon" as our natural satellite is at apogee, far in it's orbit around Earth.

Touring The Milky Way


This past winter, with much idle time, my mind wandered and dreamt of summer observing.  Fast Forward to earlier this month.  The moment arrives and the weather forecast looks promising.  The equipment is all set and it is going to be a great night!

Because the view east at my home is obstructed with trees and the opening to my south is limited, I chose to go to Schoodic Point.  The skies are a bit darker and the horizon is ideal.  I was particularly interested in points south of Messier 8 down to about -40 degrees declination, maybe a bit further if atmospheric extinction was tolerable.

I arrived at a small parking area on the east side of the Schoodic Peninsula around sunset.  Schoodic is part of Acadia National Park east of Mount Desert Island.  I had documented the dark skies here in 2008, as part of a cooperative agreement between the National Park Service and the Island Astronomy Institute.  The resulting Nightscape Survey revealed pristine skies overhead and in the areas facing away from population centers, primarily south.  The survey showed Schoodic to be a dark sky haven, quite possibly the best east of the Mississippi.  Typical Sky Quality Meter (SQM) readings average 21.75-21.85 mags/sq-arc-sec with no Milky Way overhead.

Looking southeast after sunset, the Belt of Venus appears over the Atlantic

I'm a frequent flyer at Schoodic.  I've been photographing from this beautiful location for about a decade. It is special to say the least and more and more people are discovering it.   May is the perfect time for me to arrive here for this special night.  The tourists have yet to arrive and visitors tend to be local.  May is also a great time to get a jump on the wonders of the summer sky, you just need to stay up well past midnight to see them.


The Equatorial Mount and DSLR


It only takes about 30 minutes to set up the equipment and once Polaris is visible a few minutes to polar align the mount.  The window for dark skies, the time from astronomical twilight ending and beginning would be from 10:10 PM to 2:46 AM EDT.  Moonrise would coincide with the onset of astronomical twilight at 2:45 AM.  Roughly a 4-1/2 hour window of darkness.

Checking focus on the Vixen 16x80 binoculars

As much as I had planned on doing astrophotography from this site, I was anxious to get a glimpse of the full glory of Sagittarius' Great Star Cloud and point southward.  I came equipped with a pair of Vixen 16x80 and SG2.1X42 binoculars.  Touring the Milky Way with binoculars is perhaps the easiest way to enjoy the great star masses as well as bright and dark nebulae.  Under dark skies, these smaller instruments really are the best way to see them.


The evening began with a panorama of the Milky Way rising in the east.  I used four images with a fast wide angle lens.  The view includes light domes from Machias which is the largest population center looking north. Fortunately it is in the opposite direction of where I will be looking come early morning.

The Milky Way rise!

The views became incredible as the night turned to morning.  Watching the wonders of the southern Milky Way rise over Schoodic Island was amazing.  Atmospheric extinction was average, darkening the lowest 5 degrees of visible sky.  This is seen easily in the photos, but was not unpleasant in the binoculars.  Stars were visible right to the ocean.  The effect visually was stunning!  

The Great Sagittarius Star Cloud rises over Schoodic Island.
The glow of the star cloud is reflected in the ocean waters. 

There was a fair amount of natural air glow, both red and green varieties revealed in the photographs.  As the Milky Way worked its way towards the meridian things were getting very interesting.  In the large binocular the essential bright and dark structures were obvious.  The west side of the Great Star Cloud was magnificent!  Dark structures superimposed over the great mass of suns were opaque and the whole background glowed! Words fail to describe how wondrous this object is.  My instinct upon seeing this is to sell all my photo gear and invest in more visual equipment!

The full splendor of the Galactic Center

The image above was the image I was after.  The frame sets just above the ocean line and extends beyond -40 degrees declination.  The air glow hindered the lowest portion of the image, but I am happy with it.


Wondrous Night at Schoodic

I'm taking in the view as the camera and tracking platform do its work.  Seeing this deep and this wide is a privilege.  Most Americans don't get to see this.  The night skies of this particular area of Maine are a treasure.  It needs protection.  If we ever loose sight of our home galaxy we are doomed in my opinion.  Perhaps.


The Great Rift through Aquila and Scutum

The clarity of the skies north of Sagittarius stand out.  The image of the Great rift above illustrates fine details, much of which can be seen in extensive detail in binoculars.  

Southern delights hang above illuminating Schoodic Point 

Seeing the entire tail of Scorpius above the horizon was a joy to view unaided and with the SG2.1x42 binocular.  Descriptions would fail to convey just how awesome (in the true meaning of the word) this is.  A visual feast for the avid stargazer.  In my almost 40 years of observing the night sky, this was a night to remember.



Moonrise marks the end of the night and morning light begins


The darkness is coming to an end and in the northeast Moonrise is occurring. Inspired by the hours of observing I am compelled to read aloud, alone on the peninsula, my favorite poem by none less than Robert Burnham Jr.



Midnight.....
There is no sound in the forest -
only the phantom murmur
of the far wind
and the wind's shadow drifting
as smoke
through ebon branches; there a single star
glistens in the heart of night....
A star!
Look skyward now...
and see above...INFINITY
Vast and dark and deep
and endless....your heritage:
Silent clouds of stars,
Other worlds uncountable and other suns
beyond numbering
and realms of fire-mist and star-cities
as grains of sand....
drifting...
Across the void....
Across the gulf of night....
Across the endless rain of years....
Across the ages.
Listen!
Were you the star-born you should hear
That silent music of which the ancient sages spoke
Though in silent words...
Here then is our quest
and our world
and our Home.
Come with me now, Pilgrim of the stars,
For our time is upon us and our eyes
shall see the far country
and the shining cities of Infinity
which the wise men knew
in ages past, and shall know again
in the ages yet to be.
Look to the east....there shines
the Morning Star...soon shall the sunrise come...
We await the Dawn,
Rise, oh eternal light;
Awaken the World!
With trumpets and cymbals and harp and the sound
of glad song!
And now...
The clouds of night are rolled away;
Sing welcome to the Dawn
Of the bright new day!
