Let Me Tell You About My Gear...

* Cue Wes Anderson montage scene with Mark Mothersbaugh theme music GEAR!!  I dunno maybe it's a guy thing - maybe it's just a thing.  But gear makes the hobby.

As a boy it started with baseball.  The glove was a magical extension of your body and you exercised it.  You put a ball in the web and wrapped rubber bands around break it in, you oiled it, you wore it around the house pounding your fist into it.  Your bat was your first multi-tool and you had a bucket full of spiders and baseballs of varying condition and lethality in the backyard shed.  Cleats - check.  Cap - check.  Cup - check.  Game time.

You moved on, got into music and you bought a guitar.  You had to have the cool sunburst paint job, the right strap, the right practice amp, the whammy bar, and at least one really great distortion pedal.   You experimented learning just what the perfect pick was for your personal style taking years discovering the path, the path to the perfect setup.

I went overboard when it came to skateboarding.   I had reappropriated my fishing tackle box with all its little compartments now employed in the storage of used or extra bushings, nuts, bolts, risers, washers, bearings, slightly used bearings, bearings I should throw away, casings of busted bearings stuck in old wheels, tiny wheels from the early 1990s, old trucks, my older brother's cracked trucks that I kept like a trophy, king pins, curb wax, Husker Du's, Husker Don'ts, spacers, stickers and stuffed way back underneath the bed - old cracked, snapped and "focused" (purposefully snapped in four equal pieces) skateboard decks.  And of course the stacks of VHS skate videos, dog-eared CCS catalogs, and poured over and ripped up Transworld magazines - all the various ephemera, accoutrement, and  kit and kaboodle.

And I'm not gonna even talk about $$$Sssnowboarding.

But that was all child's play, training for the real deal.  The real gear.  You see, although astrophotography has a long history of amateur involvement (first recorded astrophoto was of the moon and taken via daguerreotype by Louis Daguerre himself!) , it was mostly accomplished through dry photographic plate processes utilizing large observatory telescopes.  But throughout the 1970s-1990s with the advent of CCD (charge-coupled device) cameras, webcams, digital cameras and in combination with innovations in telescope and go-to/tracking mount technology we saw the rise of a new standing army of astrophotographers getting better and better at cheaply (relatively speaking) pulling down the heavens and stuffing them into your mindblown faces (more on the history and processes of astrophotography in a later post).

I have to give credit here to the iPhone.  That wondrous conflict-mineral laden computer/camera/phone/totem/pacifier/plaything that fits right into your pocket was instrumental in getting me hooked on the hobby.  A friend and I were out at the shore for the spring 2012 supermoon, trying as well to spy Saturn through patchy cloud cover over Long Beach and a sudden, reactionary force swooped down upon me, I thought "I'll snap a photo with my phone!" (said no one ever before this century) and within a few moments I had taken my first astrophoto:

All that is to say that I still really haven't broken out of the beginner stage and my gear list represents the culminated efforts of lots of research, a few Christmases, a few birthdays, and some extra hours at the office slowly allowing me to gain experience with multiple introductory methods and techniques.  I'm sure I'll make a few updated posts as I drop a few thousand doll-hairs and level up, but back to the present and my gear:

The Scope:

image

This is my light bucket and "she" doesn't have a name because I didn't name "her" because I don't do that crap. It's an Orion XT8 8" Dobsonian (RIP its creator, John Dobson, popularizer of 'sidewalk astronomy' who past away today 1/15/2014) Reflector (it uses a primary and secondary mirror to reflect light as opposed to a Newtonian which employs glass lenses) telescope.  This is one of the simplest telescopes you can buy and is the standard type for beginners, provided that you can haul around ~30-40 lbs. without injury.  It tilts up and down and swivels 360 degrees on it's base allowing the user full access to the heavens above with only a red dot sight (ACOG sight for you FPS gamers) mounted near the eyepiece for navigation.  This means that the scope is not computerized and you must learn your way around by 'star-hopping' through the constellations using 1) assorted astronomical facts and charts stuffed into your memory 2) star wheels 3) smartphone apps 4) big thick reference guides like Burnham's Celestial Handbook and the smaller National Audubon Society Field Guide To The Night Sky (more on books later) and one of my favorite methods 5) aimless scanning.

The Eyepieces, accessories, etc:

I use the provided 1.25" (diameter) 25mm Sirius Plossl eyepiece along with a 2x Barlow lens (effectively doubling magnification) and  I also made use of a friend's 16 and 9mm eyepieces before the move to AZ.  I plan to make the jump to wide-angle 2" eyepieces, Barlows, and filters for the increased field of view or FOV as soon as economically possible.  Solar observing and imaging is made possible by my full-aperture 8" Orion Safety Film solar filter and is an indispensable member in the arsenal, enabling  off-hours observation and imaging of sunspots and sometimes even faint filaments or other solar surface details.  I borrow binoculars for the time being, but I really want to get these snazzy image-stabilizing binos that will set me back a cool $300.  Also, absolutely necessary is a few random red, rear bike lights and especially my Energizer brand red/white headlamp (the red lights are imperative to maintaining dark adapted vision) which is always kept close.

The Imagers:

I already mentioned the iPhone.  Its a 4th generation and has nothing special about other than it being a combination phone/camera/computer that fits in my pocket and is made from minerals mined by 3rd world children.  I did make a nifty DIY mount using an old plastic smartphone case, parts from a clamp for a bike light, and a bunch of black electrician's tape.  It worked pretty well until I realized that 1) it got me no closer to doing decent long exposure iPhone photography because my long exposure app doesn't really cut the mustard (more on apps later) and 2) I could basically maintain enough steadiness with just mah two hands to accomplish what I could with a camera phone (nothing against Orion's smartphone mount, they look pretty handy).  But it was a fun exercise in making my own gear (MYOG).

My DSLR (digital single lens reflex) camera is a Canon Rebel EOS XSi (not yet modified for the IR filter).  Its one of the "quieter" cameras that Canon makes and is thus perfectly suited for the purposes of astrophotography as working with such faint or distant light sources ramps up the amount of "noise" of any given image.  I have two lenses that I am using right now, 1) a standard Canon 18-55mm f/3.5-5.6 II lens, but it is outfitted with a UV filter and combination Super Wide Angle/Macro Lens made by Neewer that all screws onto the front (all items towards the medium-low cost end of the spectrum) and 2) a Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens (which is also towards the medium-low or "intro" end of the spectrum, but seems pretty durable for the price for most anything an amateur is going to get into).

A quick aside: In Optics, the f/, or F stop or Focal Ratio is the ratio of the lens's focal length to the diameter of the entrance pupil (the image as 'seen' through the front of the lens system).  It is a dimensionless (without physicality) number that is a quantitative measure of lens speed.  As the f/ stop number increases, the aperture gets smaller and light gathering power decreases (from wikipedia) and a similar effect governs telescope optics:

I'll probably invest in some "faster" lenses as I progress, but I'm pretty psyched on my current configuration. Other than all that I have my camera bag, lens cloths, backup batteries, charger, memory cards, usb cables, a remote shutter release for all my long exposures, and a DIY film canister mounted PS3 webcam (Infrared Filter modified) for use in lunar and planetary videos which are then separated into frames and stacked to bring out detail - a technique that I haven't yet ventured into due to software deficiencies.  Also, a big ups to my moms for handing down her video camera tripod made by SUNPAK - its totally smooth and sturdy (currently trying to modify its quick release mount to be pinned to my backpack shoulder strap for use in wilderness hiking/photography) and really facilitates quick setups, operations, and mobility.

So that's about it for my gear setup and hopefully I will have to do many many many updates as you all begin to learn about prime focus adapters, focal reducers, EQ mounts, Alt/Az mounts, tracking, CCDs, Oxygen III and H-Alpha filters, SCTs vs. APO Doublet or Triplet refractors, autoguiders, all-sky cams, various software programs, dark/light/bias frames, green laser pointers and red laser collimators.  And that's not even going into how bad I want to build my own large aperture Dobsonian telescope and 360 deg. swivel binocular chair:

Soaked In Electric Light

So there I was, a budding amateur astronomer/astrophotographer trapped on an city island in blighted electronic night, "living" and working in downtown LA and Long Beach, CA.  A bike commuter to boot with no car and at the whim of the adventurous inclinations of friends who might oblige my sorry butt with a few outings per season to soak up the dark skies, not to mention wilderness for its own sake.  Hey, get me - I'm an anachronism! I had actually kind of forgot about wilderness for a minute there.  Growing up in East Mesa, Arizona the wilderness was always just down the road a spell.  Aside from skateboarding, outdoor recreation usually just wound up happening whether it was hiking, camping, mountain biking, trail running (you can't fall off a mountain), tubing down the dirty Salt River or wakeboarding and cliff jumping at the lake, up to SnoBowl or Sunrise for as much snowboarding as possible, and if you were smart/lucky you spent some of your formative years reading our patron saint of Southwestern wilderness and freedom for the human soul, Edward Abbey.  But after living in LA for a few years I had failed to notice that the outdoors had somehow been scripted out of my experience, I guess made up for by living near and frequenting the beach?

I got out to Joshua Tree National Park for a short weekend with an old friend with the specific intent of getting to at least a blue/green zone on the light pollution maps.  I made the mile hike in with a small Meade ETX-60 +tripod strapped to all my backpacking gear and long story short, clouds and cold because it was freakin' January.  But the next morning after a hearty breakfast we hiked up a mountain and slowly over the afternoon trek back down I could begin to feel the city gradually get flushed out of me as I looked and looked at wild nature all around me.  I felt drowsy and drunk and my eyeballs seemed to bug out  as I hiked.  I began to formulate hypotheses about the visual rhetoric of nature and its restorative effects on eyes too long trapped in the city looking everywhere at right angles and the stopped up movements of traffic.  Hypotheses about the visual rhetoric of forgotten faint lights emanating from distant dim stars and emission nebulas and light from our own star brightly bouncing off neighboring planets and what that may do to out physical eyeballs and the brains attached to them.  Hypotheses, not theories.

Then I got another friend to haul me out to the Goat Mountain Astronomical Research Site (GMARS) located north of J. Tree which is an amazing facility run by the Riverside Astronomical Society.

GMARS

They really do it up right at GMARS.  2 houses with beds, bathrooms, and kitchens, 24 powered concrete pads in a U-formation (plus one pad in the middle reserved for a huge Dobsonian telescope) to set up and plug in to, 15 observatory huts with retractable roofs etc., and plenty of room for parking and tent camping and every walkway is lined with red lights every few yards.  Like noobs we arrived 2 hours after dusk which meant two things: we missed the potluck/barbeque and we would have to search for this place with no headlights for fear of annoying the already dark adapted astronomers and astrophotographers.  Cut to me leading the vehicle down the road to the west of the facility with my redlight head lamp for the last 1/4 mile.

A bit after setup one of the club members showed us around and introduced us to a few of the folks doing some imaging in the huts and in general made us feel real welcome.  I loaded up a few times in the kitchen on coffee and snacks and proceeded to really open up my new (solstice miracle) 8" Dob under dark skies for the first time.  Here's my observing notes from that cold dark night:

February 9, 2013.  GMARS facility outside Landers, CA (blue zone).  8pm-3am /~30 deg. F / winds SW @ 6 mph /new moon.

Bagged M31 Andromeda galaxy, M42 Orion nebula, Jupiter + moons, C14 Double Cluster in Perseus, C13 Owl cluster and M52 open cluster in Cassiopeia, M35 - M38 open clusters, M101 Southern Pinwheel  and M51 Whirlpool galaxies,  The Leo Triplet, M104 Sombrero Galaxy (!), M13 globular cluster, a bunch of the random galaxies in Canes Venatici/Coma Berenices/Virgo, and Saturn before freezing the night away and trying to sleep in the van.

From the limited view of my front porch I continued to learn how to star hop using my dob+red dot sight and multiple star wheels, smartphone apps, reference books, and magazine articles and excitedly planned my next excursion: a grey zone camping trip near Desert Center, CA in the Chuckwalla and adjacent Orocapai Mountains Wilderness on BLM lands near the Salton Sea.  We were coming up on summer and decided to make the 3.5 hour trip so we could see the Milky Way.  Totally worth it.  We slept outside in bags and a bivy sack in a cool 55 degrees F and dozed off while watching the center of our home galaxy blaze up thick in the southeast and roll westward over the Chocolate Mountain Air Force gunnery range.  But before sleep I added M20 Triffid, M8 Lagoon, M17 Swan/Omega, M16 Eagle nebulas, M80 globular cluster, M81 Bode's and M82 Cigar galaxies to the list plus other previously viewed faves with my trusty Dob.  The next morning we checked out sunspots with my solar filter and then spent the day hiking, 4 wheelin', exploring caves and old mining depots. complete with stone houses and cyanide solution tubs and setting up camp near a ~40 ft high abandoned railway trestle that we slowly crossed before sundown.

"The clearest way into the universe is through a forest wilderness."  John Muir.  I think a desert may have to suffice Johnny, sorry.

I spent the next few months pushing my iPhone's imaging capabilities, finding double stars, learning the different mares, craters, and anomalies on the moon, getting to know my new Canon DSLR and generally wondering what to do about my situation and how to change my life.  How to script wilderness and dark skies back into my life and get into rhythm with the real action of the world.

I guess Back2Arizona to figure it all out?
