So you know tonight was a lunar eclipse... an adventure. so grab some fingerfood and relax.

I'm sending this to different folks, so if things sound too techy or locations aren't familiar, worry not and just ignore it :) ask questions (just hit "reply", not "reply all") if i totally lost you :)

The afternoon of the event, called up the chair of the physics dept, who immediately recognized me, and said i could check out the tele, no problem. good. even saw something that looked like a critical adapter that couples a camera to the telescope, one that I had bought long ago, and thought lost, figuring I must have put it in the bag with all the other couplings when returning the equipment (having checked it out a few times before)

now, i needed film (didn't want to get it if i wasn't gonna have the scope since NPH (what i planned to use) is so pricey locally, about 8 $ and change all said--more on that later). called home, bro had school till 6.30, well past when redlands camera closes. a call to two stores in riverside where i was at school was no go, both were out of NPH[*]. the next closest place was in arlington (phototorium, now wolf camera). i had an opening between 3.30 after one class and 5 before the next class (and the 5-6.30 class prof had emailed the class saying that tonight's session was NOT to be missed). so I get cleared to pick up the scope, pack it, go get the car, load it, get fuel in the car which was running on empty) and get on the road....

took all of half hour to move a couple of miles, traffic was dead stopped due to an incident in the interchange i needed to hit--found out AFTER getting stuck in the middle, no way out, gotta calm down and ride it out. once road opened up, get on the loud pedal and make it the film place. ironically, i was told to get it from redlands camera as phototorium/wolf camera would charge me through the nose, being the only other "pro" store in the area. turns out it cost 5 $ and change, LESS than redlands camera by 3$.

Already 5pm. If traffic is light, I can make class at 5.10, give or take a couple. Made it to class at 5.15, to the relief of prof who was worrying that the "regulars" were skipping a critical class. blah blah, class, blah blah.

get back on the road come home. grab some thing to eat while searching the web for the elusive exposure guide table telling me just how long to take the picture for. running through google, most of the website are very general, nothing helpful. Fred Espenak's website, which is the de facto repository of all thing loony (hahaha), well, the images won't load! either they have been taken out or the site is suffering from too much traffic and I can't access it! the exposure table is an image i wanted to print, the only format he has--and i can't get to it! the troubles are just starting: it gets better!

Changing a few keywords, etc etc and finally I get something usable to work with.

Having shot--or attempted--two previous lunar eclipses, I feel good; I know what to do, what not to do, I have the gear, I know how to put it together and strip it down quickly, it won't be so cold as to hinder finger dexterity on ice cold metal parts, clouds cleared up, a bit hazy on the horizon--which might yield a nice dark red tint to totality, so it's all good. since the first two had their own set of misadventures, i figure i've covered all the "what else can go wrong" bases, and this time, i'm gonna have a real keeper, something to hang on the wall! [**]

get in the car, drive past the lookout point onto a dirt cliff overlooking the highway: the spot farthest from ambient city lighting I could think off, far enough off the road that car lights won't be a issue. turn out quite a crowd had gathered at the lookout point to check out the eclipse, and both sides of the narrow 2 lane road were flanked with parked cars, people outside watching. wow, that was unexpected. i guess the last eclipse in january was too cold for the critters to come out :) it was pleasant weather this time around ("pleasant" enough for killer sized bugs of all sorts to be out in force. yuck).

so i slowly make my up the dirt trail trying not to bang the undercarriage of the sedan or toss up so much dirt as to piss off anyone downwind. there was one car parked smack right in the middle, so i had to "off road" through the wildflowers to get around it. top of the trail was another car parked sideways, two ppl out with tripods and cameras.

time to pull out the big glass: 8" Meade SCT. set it up quickly with help from dad, roughly aligning it with the north star (as luck would have it, I picked up a power inverter to drive the clockwork in the scope when getting the couplings and other bits). hooked it up to the car battery, and yes the beast starts ticking. set up the telrad, try to find the already very very dark moon in the upside-down backwards view. voila, a coffee colored orb hanging in the distance. nice. getting light on the left side, but i was in no hurry--i was thinking the moon would be going INTO totality. as i later learned, it was coming OUT of totality. guess my time zone conversions must have transposed digits.

since i figured the moon was yet to reach totality, might as well look at it through the scope, and worry about pictures once it went dark. bad idea.

starters, the Tmount to OM adapter needed to hitch my camera to the scope is missing. the suspect in the bag from school is something similar but for ANOTHER camera system. since they all look like a metal ring, i figured it was mine. well it wasn't. major bummer.

a quick call to home, asking bro to rummage through my camera junk to find said critical piece. and bring my other even older camera (passed down from grandfather) and the adapter for THAT camera, which I know I have (Roger Skully, if you are reading this, I believe you were the gracious individual to send me that vintage bit, gratis).

by the time my bro gets it to me, the moon looks like a diamond ring, or what is properly terms the japanese lantern effect methinks. i'm thinking, wow, very pretty. but how odd that it's takign up that effect going INTO totality, it usually happens coming OUT of totality...right? too busy trying to figure out how to rig the camera to take a picture to pay attention to time. yes, the moon was coming out of totality as i was very shocked to learn a few minutes later. oh well.

ah, but we haven't gotten to the fun part yet... the part where i couldn't fit the Tmount on the Exa (the very old camera). on one hand, i'm absolutely certain i've got the right pieces and i'm putting it on the correct way, but the darn ring won't lock into place!

before i go farther, i should note that my locking cable release, the bit that holds down the camera shutter remotely so my nervous hands don't fudge the picture, is also missing in action. some rubber bands and a paperclip are on my wrist to serve as replacements. said rubberbands are now doing duty holding the camera to the telescope tube, roughly, while i press on it to keep it stable and not rotate under its own weight. a few pictures are snapped that way. oh yes, i should mention i had loaded the olympus camera but now had to perform a mid roll rewind to load the antiquated Exa, a real pain in the neck. i think i took 3 shots that way.

so now the moon is halfway out of eclipse. and all i have is the possibility of three lousy rotten shots taken with a 40+ yr old camera rubberbanded to a telescope.

done taking a few pics, moon almost all out of eclipse, time to put the camera back. hey, what's this now? i can't get the lens back on? no way! it will twist just so, but no more, won't lock into place. this is really weird. so this means maybe i had the correct Tmount after all, maybe i need to figure out how to put it on. i mean just how hard can it be? align the red dots, insert, twist, lock. everything works except the twist/lock part. now i'm really scratching my head: not only won't this Tmount not fit, but neither will the lens i JUST took off the camera. it's an old thing, and i'm fairly certain i'm applying more force than is prudent. i know that i've done this before, and there is a slight trick to putting it back on, but i can't recall what.

pissed off, i give it a sharp twist...snap & click. it locks! so the trick was to use quite a bit of force, lot more than what i deemed necessary for an antique piece. well, now that i have it on, might as well put it on the scope and get a pic of the almost fully bright moon. snap snap.

but there is hope. 3 attempts at eclipse, i think now i've REALLY covered all the bases: the only place left is home plate--the November 8/9 2003 lunar eclipse, the last one for USA till 2007, is gonna be great. i've done all the usual foulups: bad alignment, bad timing, bad exposure, bad guiding, forgetting equipment. now there is NOTHING left to mess up. November. I'm looking for a real wall hanger then. Yessiree. that's what i said the past three times, and i'm batting .000 and you can't go below that, or as the song goes, you can't fall off the floor :) on a more realistic note, as i recall from high school statistics, just because i struck out the first two times doesn't mean i'll hit a homer the third try. but i can try! and that's half the fun.

if you read this far, you're almost there! thanks for keep up :)

so here's wishing clear skies to y'all come November, and good shooting till then!

* NPH chosen due to film speed (shoot faster shutter, not worry about vibration/tracking errors as much) and wide latitude to capture shadow/highlite information. for certain kinds of shooting, the price premium over consumer grade film is definitely worth it.

** interested parties may note my previous eclipse experience was eclipsed-- sorry for the pun--by an incredibly thick marine layer. i stayed up till 4am and drove from where i am down to the coast (75-80 miles one way) to shoot the eclipsed moon setting over the pacific. couldn't see diddly squat through the pea-soup thick salty stuff in the air. and the salty air really makes you feel icky. my first experience shooting a lunar eclipse was probably the most productive of the three, since i got one decent shot, albiet blurred (this time, the story was lining the telescope w/ polaris to track the moon would interfere with camera coupling, so i had to guide it using a very nervous hand, blindly, since you can't see through the camera while it is taking a picture! and exposures ran far too long, since i had forgotten to bring the table i so duly printed. in essense, i was guiding because i thought i needed a long exposure, when a much short one would suffice, had i had the table with me)
