Winter Visit

I have just returned from two nights at Zephyr Ridge.  I had not visited in a while, and it seemed prudent to check on my observatory because there was a recent severe windstorm in the region.  As it happened, I timed my mission to coincide with some decent weather for observing.

There is usually something to do when I visit my observatory, so I always bring a wide selection of tools.  One lesson I have learned from owning a remote observatory is to expect the unexpected, and this trip was no exception.  There were two small projects this time, one that I had planned to do and one that confirmed the need to be prepared just in case.

Evidence of the storm greeted me as soon as I turned off the highway onto the private road that leads to my property.  I had to stop twice to remove obstructions.  The top half of a tree had broken and lay across the road.  I was able to push it aside in a few minutes.  Further along the road a small tree had been uprooted, and again I moved it off the road.

Fortunately my observatory was in pretty good shape overall, although it did not escape unscathed.  The 2” PVC exhaust pipe for the composting toilet fan system had been torn from the building.  The wind literally ripped one of the mounting brackets off the building and the pipe snapped. (See photo, taken after remounting the top bracket.) I found the top half not far away.  With the help of some duct tape (never leave home without it!) and a new screw for the bracket, I was able to perform a quickie repair, but I plan to get replacement PVC to do a proper repair on my next visit.

A more long-term issue has arisen that I discovered on my last visit.  The isolated concrete pier is now about 3/8” below the level of the surrounding slab, giving the impression that it has sunk.  In fact, I believe the pier has not moved, as the way it was constructed makes movement highly unlikely, as is desirable for a permanent pier.  Instead, I believe water has gotten under the slab and caused the middle of the slab to rise, perhaps due to freezing.  There are minor cracks on the surface of the concrete and a bubble level showed a slight slope downwards to the edges of the slab, confirming my diagnosis.

The A-frame roof of the observatory has no gutter system.  Having a moving roof makes gutter installation more problematic.  So, it is plausible that water flowing off the roof to the base of the foundation is causing the slab problem.  I brought a roll of 6 mil plastic sheeting with me on this trip.  I installed a three-foot barrier of this material around the east and west sides of building (see photo), where the roof run-off occurs.  I will need to get more gravel to cover the plastic, but this should help divert the water further away from the foundation.

The weather was quite cold while I was there.  The daytime temperature hovered in the low 20s F, and after sunset the temperature dropped to the low teens.  It made for frigid conditions for observing, but I did enjoy a clear sky in the early morning of Feb. 1, and again in the evening on the same day.  I will report on my observations in a subsequent post, which I will prepare as soon as I have compiled my logs.

Opening

Be humble for you are made of earth. Be noble for you are made of stars.  ~ Serbian proverb

Many amateur astronomers enjoy spending time under a clear sky.  Some set up a telescope in their backyard, while others haul their gear to a darker site outside of town.  For many years I did both, and still do, but now I have an observatory set in a very dark location.  I built it so that I could view the night sky more comfortably and conveniently, and have a ready shelter when it is time to rest.  Other than that, I did not expect the experience of observing to be much different than it was before.

It has been different.  Owning a remote property with an observatory has enhanced my experience of both the sky and the earth, and has allowed me to see, hear, and feel the natural rhythms that I often take for granted when surrounded by the “stuff” of modern life.  One reason for this is that having a shelter allows me to stay for multiple nights in reasonable comfort, and often I am there alone which helps me to quiet my mental chatter and engage my senses more readily.  I suppose those who have remote cabins or favorite camping spots have a similar experience, but my hangout is unique in that it is designed for viewing the night sky, and so my most open and perceptive time is when others are usually asleep.

My observatory is about the size of a large garage.  The roof literally rolls on rails, which is a remarkable concept for most people, but a well-known design to astronomers.  I always feel a peculiar anticipation when I start the motor and watch the roof over my head roll away, exposing the night sky.  I feel excitement and also a little trepidation, as my formerly secure building is now in a state of vulnerability.  The juxtaposition of being under a sound roof one minute and then opening the roof to the night is both a physical and psychological transition; the sense of protection of being covered by the roof is relinquished and replaced by the expansive feeling of being in direct contact with our seemingly limitless universe.

I allow this feeling to gradually pass as I get down to the business of preparing my telescope.  As my eyes adjust, I assess the conditions in a technical fashion:  How transparent is the sky?  Are the stars looking reasonably steady or twinkling noticeably?  Is there wind?  With the reference of many previous nights at my observatory, I have come to know my sky and can quickly gauge how far from ideal the conditions are that night.

Then I begin to find and observe the objects on my list.  Some are familiar to me from previous sightings, but most are new to me, as the sky is a virtually unlimited treasure chest.  I am alone with the universe and it feels as if I am the only person on our planet paying attention to the vast realm above.  Galaxies containing billions of stars – some perhaps with planets – come into view, each with their own shape and some with unusual features that I note in my digital voice recorder.  Nebulae, star clusters, and other intra-galactic objects also come into view.  I see them all in the moment; I am not viewing a photograph in my easy chair, but experiencing the photons from afar in real time.

Although I use my eyes through the eyepiece, my other senses are also engaged.  It is so quiet that I am in tune with the sounds of the night.  Distant packs of coyotes often serenade me.  One evening I listened to the call of an owl that continued for hours. Sometimes the distant sound of a motor vehicle reminds me that I am not the only human left on the planet.  I feel the subtle changes in the breeze, and the gradually cooling air.  Once I felt a sudden brush of air as a creature, possibly a bat, flew above me, pausing just long enough for me to look up in surprise before it continued on its way.

I often take time out from the rigorous observations through my telescope to simply gaze upwards and admire the grandeur of the night sky.  There is nothing more beautiful to my eye than the sky at a dark location, where the intrusive glow of city lights is absent and the Milky Way extends vividly across the sky showing both shape and structure.  I am connected in a personal way to all that exists in the vast cosmos.  I can pick any of the original works of art in creation itself, and point my telescope to it.

Even though I have a plan for my observing sessions, I am often surprised by the unexpected.  I have seen many meteors streaking across the sky.  Some have been dazzling.  Two bright meteors last summer were preceded by a bright flash, like the flash bulb of a camera, disorienting me for a moment.  I was amazed by the brief and fiery violence, all in complete silence.  As others sleep, I see celestial events happen in real time.

As the night progresses, I am aware of many changes.  The dependability of the earth’s rotation moves the sky like a slideshow.  Constellations move to the western sky and are replaced by new ones in the east.  The air continues to cool, and I retreat into my warm room to put my hands in front of the heater.  I am changing as well.  Fatigue is pressing on me, in a tug of war with the celestial energy I am absorbing.  It’s a sort of “astronomer’s high.”  I am too tired to go on, but too connected and engrossed to stop.

Eventually I do stop, whether due to fatigue or the faint light of astronomical twilight, signaling the impending dawn.  I cover the optics and turn everything off.  Then I press the button to close the roof over my head, saying goodbye to the night.

Generally it takes some time for me to fall asleep and my sleep is usually fitful.  I am still energized by the sky and all that I beheld.  Also, I anticipate the dawn.  Some astronomers are able to sleep late after such nights, but I am unable to do so.  When the sun rises at my observatory, I sense it and awaken even though the blackout shades on my windows block almost all the light.

The sun is one of billions of stars in our galaxy, but it is our star, and when it rises it dominates the sky.  The blue scattered light of the daytime sky suppresses my awareness of the vast depths, incalculable sizes, and imponderable persistence in time of our universe.  The sun brings my attention back to planet earth, and I experience light, the warming air, and the stirring of creatures and insects.  I sometimes open my observatory roof during the day, and when I do the feeling is different.  I no longer experience contact with the vast reaches beyond our planet, as my attention is drawn to the local shroud of blue that is our atmosphere.  The day brings me home from the long journey of the night.

When I ventured to build an observatory, my reasons seemed simple and easy to describe.  I wanted a location with a dark sky where I could take full advantage of my optical instruments, and a shelter for comfort and convenience.  I did not anticipate the deeper connections that arise from spending time there.  Zephyr Ridge Observatory has not only enhanced my ability to observe the many distant jewels of our universe; it has enabled me to perceive the transitions in our daily cycle in a more direct way, to embody the expansive openness of the clear night sky and the reassuring return of daylight.  And with this I am becoming a more genuine astronomer.
