Lunar Eclipse, 12/10/11

Some handheld shots of the total eclipse of the moon this morning (Saturday, Dec. 10, 2011), as seen from my driveway.  It's the last total eclipse until 2014.
Shot at 200mm zoom, 3200 ISO, 1 second exposure (except the fourth shot, 1/8th)

Total eclipse occured at 7:06 am, at which point it disappeared behind the hill.  I climbed to a higher vantage point, but the moon was virtually invisible, as the sunrise was officially at 7:22 am and moonset was at officially 7:25 am (but only for people with a perfect view of the horizon).

My Review of Therm-a-Rest NeoAir Sleeping Pad - Regular

Originally submitted at REI

Backpacker April ’09 says of the Therm-a-Rest NeoAir sleeping pad, “You’d think this pad had a built-in espresso maker after seeing the way testers bounced up in the morning.”

My Review of Black Diamond Storm Headlamp

Originally submitted at REI

The waterproof Black Diamond Storm headlamp is built to withstand the worst weather, because the last thing you need when caught in a storm is for your headlamp to die.

Pros: Bright, Long battery life, Adjustable Beam

Cons: Heavy, Bulky

Describe Yourself: Avid Adventurer

Was this a gift?: No

Here's a followup to my earlier review: I replaced the alkaline batteries with Energizer Advanced Lithium AAA's. Here's the weight comparisons:

BD Storm w/4 alkalines.... 3.8oz, 108g
BG Storm w/4 lithiums.... 3.2oz, 90g
Petzl Tikka Plus w/3 alkalines.... 2.6oz, 76g

The 0.6 oz weight savings makes a BIG DIFFERENCE. It doesn't bounce nearly as much when jogging, and just feels better on the forehead. That said, it still is nowhere as comfortable as the Tikka Plus. I put on the Tikka by accident the other night and thought, "This feels great!" Sigh.

But for me, the powerful beams make up for the weight.

I also put a piece of duct tape below the beam in the shape of a mini-visor, ala Petzl. It helps a little on the glasses glare. Overall it doesn't bother me that much. I got the orange model because it's easier to locate on the ground or in a dark tent, right? But "napcop" has a good point: get the black housing if light bleed bothers you.

superb features, but a little heavy

Pros: Adjustable Beam, Long battery life, Bright

Cons: Bulky, Heavy

Describe Yourself: Avid Adventurer

Was this a gift?: No

Here is my first impression of the Storm, after two days and two walks on moonless nights:

Pros:
•super bright high beam
•wide and bright low beam
•wide, relatively bright red beam
•it remembers the red setting until you switch back to white light
•infinite adjustable brightness for high and low beams
•waterproof (IPX7)
•batteries are easy to access
•regulated—won't gradually get dimmer
•switch is easy to feel, even with gloves
•four tilt positions are adequate, feel solid
•lockable
•battery indicator
•battery life is just as long as the Spot, even though it's almost 50% brighter

Cons:
•it's heavy: 3.9 ounces with alkaline batteries
•it's bigger and bulkier (than the Tikka)
•it's less comfortable on my forehead
•the switching system is a little bothersome
•it reflects in the top of my glasses frames

My old headlamp is a Petzl Tikka Plus. It weighs 2.7 ounces with 3 batteries. The Storm weighs 3.9 ounces. It uses four AAA batteries, rather ingeniously shoehorned into the same space as the Spot. Lithium batteries would shave half an ounce off the weight—a welcome improvement.

Black Diamond says the range is 70m, same as the Spot. I think they're being modest. I was able to illuminate hills that were 200m away, and I could reasonably see objects at least 100m away (I stepped it off). While I wouldn't use the high beam frequently around camp, it is really nice to be able to see things (bears, maybe?) in the distance very clearly (oh, it's my dog). It is, of course, too bright for use in camp unless you dim it, but for camp use the low beams are ideal.

The low beams (a pair of "SinglePower LEDs") illuminate a nice wide area—we're talking a good 20 feet on either side and ahead of you, making walking and general nighttime tasks a piece of cake!

The red LED is brighter than the Petzl Tikka XP2 (at least when compared in the REI bathroom). Once my night vision kicked in, I could easily see 20 feet, maybe more.

The infinite dimmer feature is a nice touch: you hold down the switch and it steadily dims until it reaches the lowest setting, when it blinks as a signal. Then you can hold the switch to make it brighter, and it blinks again to indicate full brightness. This surpasses the disappointing Petzl XP2 with only one low brightness.

Because the beams are so bright, they reflect in the top of my glasses (my little Petzl had a lip that prevented light bleed). I don't think it's a deal breaker, however. I tried a piece of electrical tape, but it seemed to make very little difference and the tape blocked the red LEDs, which aim more downward.

The system of switching between high and low may take a little getting used to. It is admittedly a bit of an annoyance that every time you turn it on, it is in a different setting: high, off, low, off, etc. To get the low setting, you must press the button three times. Be careful: if you press too quickly, you get the flashing mode instead! Not entirely sure why Black Diamond didn't offer the stepping options like the Petzl. But you learn to work with the system and it's okay.

Once you go into red mode (by holding the switch for 3 seconds), it stays in red mode every time you turn it on, until you return to white light (hold 3 seconds again).

Hold the switch for 6 seconds, and it locks in "off" mode. Very nice when desired.

A thumbscrew holds the battery compartment tight (waterproof). It's easy enough to unscrew, even though has a tight hold. The batteries are easy to change, but pay attention to which direction they go: it's marked, but this may be a challenge to figure out in the dark. The fourth battery is nestled behind the outer three: Black Diamond found a way to get an extra battery in a space no larger than the Spot!

The Storm is also regulated, unlike the Spot or Tikka XP2. That means it retains the same brightness throughout, until the batteries die. A battery indicator changes color to warn you (if you remember to check it). I've never used a regulated LED, but I already like the concept. The downside is, once the batteries drop below a certain threshold, you're out of light, unlike the unregulated models that just get dimmer and dimmer.

The Storm is bulkier than my old Petzl Tikka Plus. The latter was SO comfortable I could forget I had it on. Initial impression is that the Storm seems to bounce a little on the forehead, which is disappointing. I immediately noticed an irritation where it rubs my forehead: I'll give it more time before deciding if that's going to be a long term problem.

Bottom line: if you want the versatility of a super high beam, a broad low beam, an infinite brightness, and a bright red beam, all under 4 ounces, the Storm is the best bang for the buck.

I finally did it.  I ended my Long Term Relationship.
 
She was the best I ever had, and I was sorry to tell her goodbye.  We literally grew up together, and she never let me down (well, hardly ever).  Whenever I needed her, she was always there, even when nobody else was.
 
But in the end, I just realized I didn't need her anymore.  Or rather, she just wasn't worth it.
 
I first hooked up with her when I went away to college in 1975.  But after 36 years together, I finally cut the cord. 
 
Literally.
 
I called Ma Bell and told her "It's over."  Okay, actually I called her daughter, Qwest, and said, "I never want to hear from you again."  Please disconnect.
 
----------------------------------------------
 
For those of us who grew up with Ma Bell (in Colorado, that was Mountain Bell), it's a sad realization that something as American as your home phone has come to an end.  No more listing in the phone book.  No more phone book, for that matter.  Who says "I'm in the book" anymore?
 
Those old phones (ours were both wall phones, a lovely beige) always worked.  Voice quality was almost always perfect.  If it wasn't, you said, "It sounds like you're calling long distance."  But the phone was always there, even when the power wasn't.  A phone call from grandpa was a family event, all of us huddled around the two phones (or running madly for Dad's office, hoping not to miss anything important before we could pick it up). 
 
Long distance calls, of course, were expensive, rare, and kept as short as possible (except when grandpa was paying).  The phrase "It's long distance" sent a shiver down your spine:  whoever it is, this is important! 
 
And of course, there were no fancy ringtones.  The ring had one tone: the tone of the metal ringer inside the phone!  What else would it possibly sound like, after all?
 
When I was a kid (as in the 1960s), our phone number in small town Wray, Colorado, was "39."  That's not thirty-nine, that's "Three Nine."  Mother ingrained in us: "If you are ever lost, go up to anyone and tell them to call Three Nine."  Thankfully I never had to do that.  Then again, it was a small town: everyone knew Dr. Neuswanger, the veterinarian.  All I would have needed was to say, "I'm Doc Neuswanger's boy" and they'd know what to do. 
 
But this further begs the question: how do you get lost in a town that's one mile across?  Downtown was never more than 10 blocks away.  I walked home (yes, uphill) for a mile many times.  I rode my bike from end to end in maybe 20 minutes (they were heavy bikes back then!).  Didn't wear a helmet and never had a problem.  I'm sure more than one driver slowed down or swung wide to cut me a break.
 
Ah, but I seem to have wandered far afield from the topic:  cutting the cord.  Then again, Mother died last year and Dad is in a nursing home 180 miles away from his homestead.  The old phone was finally retired in 2009 after the folks moved to Assisted Living.  Actually, they kept it for a year: it was the only way we could communicate from the house to the center when us kids visited.  After we finally dropped the landline, we were in a jam because the cell tower didn't penetrate the bluff next to the house.  We could drive a mile into town and get service...or drive two miles and just talk to them in person!
 
Today the old phone number still serves one useful purpose:  it's an easy to remember PIN number!  And unless you grew up in Wray and called Doc a lot, no one out there knows remembers what it is. 
 
There's a mark of distinction:  how many people have the same phone number for 40 years?  Or the same address?  Or the same spouse?  Forty years doesn't seem that long, but in today's world, it's almost unattainable for most poeple, I think.
 
Maybe that's why 40 was so important for God to require that his people wait.  He knew what was coming.
