Cayman – Chapter Two: Lights, Camera, Action

9/4/15 – Cobalt Coast, West Bay, Grand Cayman

A moment is fleeting – light and shape appear and disappear within the same instant.  A picture, however, allows time to stand still, freezing the tide and the turning of the world for us to remember how beautiful things truly were.


Cameras are capable of perceiving things that our eyes and our minds simply cannot.  The tools we use as photographers become part of our thought process – aperture, exposure, composition.  But none of that matters unless we put ourselves in a place worthy of imaging.  Every corner of this island is more than worthy.  If we do not look, these moments will gladly pass us by.  We have spent the past few days looking further than usual, searching for those wavelengths of life that are difficult to see during the normal daily routine.  Work, traffic, relationships – all flood our concentration, yet, natural beauty quietly happens in the background.  To see something different you must shine a different light (both figuratively as well as literally).  We put away our regular white lights and entered the water with our fluorescent blue lights (black lights) and yellow filters.  Hard corals utilize certain proteins and algae as a semi-sunscreen that we cannot see until the fluoro lights come out to play – normally orange, brown, or ‘clear’ corals and anemones become vibrant green and purple glows.  As we moved across the top of the reef, our fluoro lights lit up certain animals as others disappeared into the inky dark of night.  Think halfway between an alien abduction and an Ibiza nightclub.  Some parts of the reef were glowing so brightly it seemed to entrance us, leading us deeper over the ledge – we’re almost out of air, but wait, the next section looks even brighter…


Even after our weird fluorescent lights are put away, the life across this island doesn’t cease to amaze.  The sun shines through the surface through what seems like an infinite amount of water, illuminating more life than I could even begin to grasp.  The bathymetry (underwater topography) cuts the ocean like a knife.  Giant pillars of rock erupt from the depths up towards the surface where we can only see the peak.  Walls hug the coast like a close friend, bending out to sea creating mountain ranges blanketed by color – we dive spots 30 ft deep, then swim a stone’s throw away, and suddenly you can look down and watch the ocean floor vanish below 500 ft, too dark to see – what else is down there…  Day becomes night and all of this is concealed.  The once friendly ex-USS Kittiwake wreck turns into something more sinister, something too moody to describe in words.  I found myself moving across the massive ship in complete darkness, not taking many pictures because my camera simply could not steal my eyes away from the scenes around me.  Luckily, the video camera was running the entire time and I look forward to creating a video to share this experience with you all – moments I truly will not, or cannot, forget.  Frightening to the point of magnificence…


The sun rises and black turns to blue again.  The night shift disappears into the deep as the daytime residents begin to mobilize.  Damselfish dart about their morning routine, blennies poke their heads up to say good morning, sea fans regain their color and begin to dance again in the current.  There, literally, is not one inch of uninhabited space in these beautiful waters, so the animals have no choice but to coexist.  We sat and watched as the ‘cleaning stations’ opened up for the day where groupers and angelfish come to get ‘cleaned’ – gobies and shrimp climb aboard the much larger fish and eat parasites, a symbiotic relationship where predator and prey put aside their differences to help each other.   Our friends brought some bait squid underwater and before we knew it it was a stingray society meeting.  Once the food was gone, they stayed around wanting to be pet.  Massive rays acted like puppy dogs – they like getting their face rubbed, almost falling asleep under our little scratches.  After the cacophony of action, I saw one ray out in the sand, away from the fray.  I put my camera down and spent a moment with her, we stared into each others’ eyes.  Nothing was said, so much was said…


I’ve learned so much about myself here.  The ocean has always been more than just water to me – and now, Grand Cayman is more than just an island to me.  Yes, there are tourist hotels, giant cruise ships, and duty free shopping, but none of that is what I see.  We have found our own corner, a corner carved by the sea and modeled by its ocean inhabitants.  The people we’ve met here have taught me so much and treated me like one of their own although I am still just a freshman in this aqua fraternity.  We will leave, but Cayman will never leave us.  Until next time, cheers Cobalt Coast.

Cayman – Chapter 1: Rain or Shine

9/1/15 – Cobalt Coast, West Bay, Grand Cayman

Hurricane Erika threatened to put a damper on our dive expedition, but Mother Nature seems to have a way of providing surprises.


I’ve been around the big drink for as long as I can remember – but I have never seen the ocean go from dead flat to 4 foot perfect beach break in an hour.  These were my first visions of Cobalt Coast.  Every surfer knows the feeling, you go somewhere without a board, there will be waves.  However, as fast as Hurricane Erika sent the swell in, is equally as fast as it dissipated.  We came here to dive, so I can safely say this may be the only time I was happy to see the swell disappear over the horizon.  Crystal clear water and unreal ocean life greeted us from the moment we stepped off of the Divetech boat on the first day.  Sheer wall drop-offs lead divers from the safety of 20 ft sandy bottoms to seemingly infinite abyss of darkness as deep as you can imagine.  Corals and sponges create structure and color that even the imagination becomes jealous of.  It seems almost laborious to take in the massive grander that is the Caribbean dive scene (a task we openly welcome).  The north wall runs along the coast, a thin barrier between the protected shallow inshore and the pelagic expanse stretching between Grand Cayman and Cuba.  We descended down into the dark blue in sheer amazement of what the Caribbean was offering us.


The abundance and variety of ocean life here is almost laughable.  From massive Mutton Snapper to the tiniest Blennies, the reef looks like the natural I-95 during rush hour.  Each and every animal has its own personality – Green turtles cruise right up to take a nibble off our lens (or maybe ask to join our selfies), massive Pompano cruise overhead like watchdogs waiting to divebomb for unsuspecting meals, tiny Blue Chromis dart together over the corals like a group rehearsing for the most incredible natural ballet.  Water here pulses like a heartbeat.


The Ex-USS Kittiwake lies just around the corner from our dock.  Rising impressively from the bottom, the de-commissioned submarine recovery vessel serves its new purpose as an artificial home for fish and sponges while creating moody vistas for photographers.  A massive sand ‘chute’ leads upward from 300 ft towards the wreck like a beige ski run, walled in on both sides by vertical walls sporting colors spanning the entire spectrum.  Giant groupers watched carefully as we approached with our strobes firing – the underwater paparazzi has officially arrived.


Cobalt Coast has provided us with unbelievable views and what will soon be permanent memories.  For us Williams boys, this is truly paradise.  I could imagine diving here everyday and never becoming even close to bored with the scenery, ocean life, or people.  So far, every night has ended with rain tapping down on our windows – we begin the day in the water and end the day dreaming of returning to it.  Sounds of bubbles rise over the pattering rainfall… the dream doesn’t seem to end when tomorrow arrives.

Underwater AstroImaging

A number of people have asked me how the 2014 Florida Keys Winter Star Party was – after all, it was a landmark 30th anniversary of this venerable astro-event. I tell them in a word: wet”!! 


Imaging from inside MarineLab – See the images here or continue reading

They figure I meant the weather was lousy and rainy. But, in fact, it was just the opposite – gorgeous warm, clear and steady almost all week which meant scuba diving during the day and observing deep southern objects including the Southern Cross, Keyhole Nebula, and Omega Centauri after dark.  But it was wet for me because most of my imaging during the star party was performed by accessing my Chiefland Observatory about 400 miles away from a underwater habitat called MarineLab submerged 25 feet underwater in Key Largo.  MarineLab is a steel structure built by the midshipmen of the US Naval Academy as an exercise in oceaneering that has ended up in a lagoon in Key Largo serving for about 3 decades as an educational venue for saturation divers and marine biologists. The structure is composed of a surplus water tank 16 feet long by 8 foot in diameter with an acrylic sphere underneath I affectionately call the “womb”.


Having scuba dived the MarineLab a month ago, I wanted to combine my two hobbies (astronomical and underwater photography) so I carefully picked the perfect night (Friday night, Mar. 1) when it was awesomely clear and dry at Chiefland and during a night when the underwater Lab was available. I was greeted by longtime MarineLab Director and marine biologist Chris Olstad in his wetsuit at sunset and within minutes we were descending using hookahs and weighted-watertight suitcases, holding my new laptop, to innerspace 25 feet down where we would study the heavens. The lagoon in which the Lab sits is full of tropical fish, a great variety of invertebrates and even an ROV (remote operated vehicle) with which Chris surprised us on our first visit!

We descended down to the lab entering through a small porthole on the bottom, donned our gear, dried off and assessed the integrity of the laptop (Luckily OK!), we were opening the observatory using the internet via LogMeIn on my laptop and equilibrating the telescope which sat 400 miles away in Chiefland, FL. At the same time, we were witnessing shrimp scampering about the porthole window trying to escape the hungry fish. By 3AM, the same fish came by with BIG bellies full of shrimp! I guess the Lab lights attracted the shrimp and made them visible and easy pickings for the snappers! Once inside the habitat around 7PM, and having hooked up the new solid-state hard drive laptop up to the internet cable, we were thrilled that the connection was good and we could communicate with the observatory via internet!  We began with the Andromeda Galaxy, which has two bright satellite galaxies: M32 and M110. We did great on both as well as capturing the southwest arm of the Andromeda Galaxy.  M33 is a face-on galaxy while NGC1055 is edge-on. Notice all the dust in Andromeda – even Andromeda satellite galaxy M110 has some dust!  The Uranus image does show several moons but the resolution is poor due to the low elevation of Uranus at that time looking through 3.69 atmospheres in the west!  Regardless, we were able to ferret out Uranus’s satellites Oberon, Titania and Ariel as well as an incidental background faint galaxy NGC202! Uranus was a great place to start our astrosafari …. relatively close to home!


We made a great effort on the Orion Nebula taking LRGB images as well as a narrowband sulfur (SII) images!  The trapezium in the deep interior is a group of hot stars powering the Orion Nebula!  The trapezium is well seen in a number of our exposures, especially in the narrowband SII image.  At 10PM, after soaking down the Orion Nebula, we stayed in the constellation Orion imaging the Flame Nebula (NGC2024) which is an imaging challenge because it includes bright bluish star zeta Orionis which is one the three bright stars in Orion’s belt.  That star created color round artifacts seen in the upper left of the image.  Artificial satellites can be seen running through the image when red and green filters were being used.  We also imaged a star cluster NGC2169 that coincidentally resembles “37”. We continued on to the Hubble’s Variable Nebula (NGC2261) which looks like a comet but is a reflection nebula. Two images of the Rosette Nebula were next, one with a clear filter and the other with ahydrogen-alpha filter showing well-defined dark Bok globules and tendrils standing out against a bright emission nebula with suppressed stars. The hydrogen-alpha filter used for the narrowband Rosette Nebula image has a bandpass of only 5nm centered on 656nm (red), the wavelength at which ionized hydrogen (H-alpha) emits (which is the predominate emission of many nebula) and provides tremendous contrast by excluding all other wavelengths of light.


After 11PM, we were just getting cooking as we went south to capture a dying star planetary ring nebula NGC2438 superimposed on a large open star cluster M46. Another open star cluster deep in the southern skies is NGC2477 in the constellation Puppis. The Eskimo Nebula is a dying star planetary nebula resembling an eskimo – also called the “Clown Face” Nebula.  Of course, we had to violate the Jellyfish Nebula (IC443) which is a supernova remnant in Gemini.  I felt it only fitting to photograph a ‘jellyfish’ while 5 fathoms deep!  Moving from object to object we banked all sorts of data documenting a variety of celestial bodies.  After midnight, we ventured close to home imaging Jupiter and its four Galilean satellites.  Jupiter has many more moons but they were too faint for us to capture.  Coincidentally, we next went to a planetary nebula called the “Ghost of Jupiter” NGC3242 which, I guess, someone thought resembles an out-of-focus Jupiter.  This is a small object in which we got some decent detail, like the Eskimo Nebula, another small but bright planetary (dying star) nebula.  Next we visited the northern Cigar Galaxy M82 which just had a supernova event discovered one month before our MarineLab effort. I unknowingly took a pre-discovery image of this supernova in early January 2014 as part of my preparation for this MarineLab expedition and did not recognize that the supernova was there at the time or I would have been the discoverer!

Late this night, we went from Saturn, 75 light-minutes away, to a quasar 2.4 BILLION light-years away! The Saturn image shows the planet overexposed to reveal the moons which are identified on the image. Other moons are lost in Saturn’s glare. I added an inverted image of Saturn we took in the overexposed blob for size perspective. Saturn’s brightest moon, Titan, is the only Solar System moon with a dense atmosphere. Next, we toured far south capturing giant globular cluster Omega Centauri (NGC5139) which was our southernmost object, greatly affected by turbulent atmosphere. We were imaging through 4.39 atmospheres to capture this image so the stars in the close-up are of poor quality. Nevertheless, you can see the yellow and blue stars that compose the bulk of the globular stellar population. At this point, Chris made a night dive peering at me through the MarineLab porthole watching me download the globular cluster images as fish full of shrimp surrounded him! While the Omega sequence was happening, I made a trip into the acrylic bubble under the Lab for a video/photo op by diver Chris. Once back at our stations, we studied a peculiar galaxy near Omega Centauri that is a strong radio source which may represent a collision of two galaxies with a big dust band (NGC5128) also very low in Centaurus. Crazy as it was, we next pointed the telescope (barely over the observatory roof) to the extreme southeast to see an object in the summer Milky Way as it rose, namely the dark nebula B72 or Snake Nebula. At this point, Chris got very excited about tackling the summer stuff but I was getting exhausted and the gable of my observatory roof (which opens to the east) greatly hindered us from going there anyway. So, lastly, we went to two very distant objects. Abell2151 is a galaxy cluster 500 Million light-years away in the constellation Hercules. We did a 5 minute exposure and the inverted version shows a great galaxy morphologic bonanza! But that galaxy cluster was close compared to our last object captured a 4:17AM. Quasar 3C 273 is 2.4 Billion light-years away and even showed us her optical jet! With that, we called it a night, warmed up the CCD camera, parked the telescope, closed up the observatory (all remotely, of course) and made a night dive to the surface 25 feet up where were greeted by the rising summer Milky Way and a warm breeze. Not bad for one night’s effort! We both had cosmic dreams. Mission – accomplished!
