Tell Me The Truth
said Ian. "About what?" I asked.
"You." He said. "And Christmas."
"What's that, buddy?"
"You're really Santa Claus."
"Uh oh," I thought. Is this the year? "Why do you think I'm Santa Claus?"
"Your beard has that white part, and I heard you going 'ho, ho, ho.'"

Gift Idea
OK, I know. It's been forever since this thing got updated. But here's the deal. The Astronomy Gods have been offended somewhere, because the weather has sucked for the last, well, forever. But as soon as that changes, I'm gonna be right out there sucking down some photons. Mars is coming soon.
Meanwhile, the holiday gift giving season is upon us. And I know, you're all wondering, what does imjeffp want to find under the tree on the big morning? My friends, look no further (or farther, or whatever)--this could well be heaven in a jar.
Baconnaise.
Yup.
Now, I've not had the opportunity to try this stuff, but Lord! IT'S BACON! AND MAYONNAISE! TOGETHER!
So please, Santa, you know I've been good. At least nothing the grand jury could pin on me. Do me a favor this year.

Wings Over Houston
I paid a little extra this year to sit in the "Photo Pit" for the Wings Over Houston air show, and I'm glad I did. I don't recall the exact number of shots I took, but I filled up three 1 GB memory cards. I rented a 300-mm image-stabilized telephoto lens, and I think that made all the difference. Look for a calendar coming soon.

It's Popcorn Time!
Hi friends. How would you like to help support Ian's Cub Scout pack? Maybe help pay for a kid to go camping? Or help one with a Pinewood Derby Car? Or just pay for the patches on his uniform? You can do all of that and more when you buy popcorn! 70% of your purchase goes to the Scouts, but 100% of your purchase will be delicious!
Send me an email if you're interested, and I'll make sure your order gets to you.

A Prediction
Sorry for the long delay folks. When you have a month of clouds, there's just not much astronomy to write about. I was all set to shoot the LCROSS impact, but after seeing the lack of results from everyone else, I'm not too upset to be clouded out.
Anyway, to fill the time, here's my prediction for this weekend's Texas-OU game. OU leading at the half, 7-3. Texas comes back in the second half to get the win, 13-7. Texas's only touchdown will come from a turnover or a return.

Second Jupiter of the Year
A little soft in worsening seeing. The moons are Ganymede and Europa. If I had stayed up another couple of hours we could have tried to catch them in front of the planet. Oh well. Finally got the LX200 remounted in the observatory--I told myself I was going to wait until we got a break from 100-degree days. We may have a few left, but it IS September, right?

An iPhone App I'd Like To See
Since I've been using with my iPhone for a while now, I've come up with an app I'd like to play with: all six primary flight instruments, aka the "six pack."
I've been looking at other apps and thinking how this would work.
1. Airspeed. Easy enough. There are speedometer apps that use the info from the GPS. Wouldn't be true airspeed without a pitot tube, but close enough for make believe.
2. Attitude Indicator. Get the info from the iPhone's accelerometers. I found a couple of not very nice-looking apps that do this already.
3. Altimeter. Found a couple of good-looking apps that do this. Uses the info from the GPS, so subject to the inaccuracies there.
4. Turn Coordinator. This might be a little harder, but should be doable. The ball is just a level, easy enough. I think you could do the turn needle using the iPhone compass and measuring the rate of change.
5. Directional Gyro. Uses the compass built in to the 3GS phone.
6. Vertical Speed Indicator. Measure the rate of change on the altimeter.
As far as the interface, I'd start with a screen showing all six indicators in the standard layout. Tapping on one would blow it up to full screen. Tapping again would return to the wide view.
Easy enough, no? I'd pay $4.99 to $9.99 for a really nice, realistic-looking, app.
Version II
Same info as the six-pack, but combined EFIS-style Primary Flight Display.

Thoughts on New PCs
On one of the message boards I read, a poster was talking about the new Windows PC she just purchased. There were several replies about "be sure to install a firewall," "make sure you update the anti-virus software," and suggestions for a malware scanner and removal tool.
The poster's reply was "Thanks! It's at the shop right now, having my old files transferred to it!"
All this got me to thinking, "Does this sound normal to most PC users? That buying a new machine involves an immediate need to install a bunch of 3rd party tools before connecting to the internet, and that transferring data requires a professional?"
You see, I was thinking about my last new Mac. I took it out of the box. I turned it on. I connected a Firewire cable between the old Mac and the new one and Migration Assistant moved all of my info over. And that was it.
So, do those of you using PCs really think that her experience was normal? 'Cause to me, it sounds like a big pain in the rear.

Naive Thoughts on Health Care Reform
I'm no expert, but I think:
Health insurance needs to separate from employment. "A public plan takes away our right to choose our coverage." Bull. If you're like me, you don't have any choice about your coverage now--you get the plan selected by your employer. Your job doesn't provide your auto insurance or your homeowners/renter's coverage, why should health coverage be any different? Employers benefit not only from not having to provide coverage, but from eliminating the people needed to administer and shop for their programs. Less money needed for benefits means more money for salaries.
A public plan doesn't eliminate private coverage. Take Medicare for example; you still need supplemental coverage for what Medicare does and doesn't pay.
How about this? Use Medicare as a model, and cover all citizens with a limited, basic plan. Allow individuals to purchase their own supplemental health coverage, just as they now do for anything else they insure. Competition results in improved plans
Can't afford the supplemental insurance? You can still see a doctor without going to the ER (probably the most expensive way to see a doctor now). The doc still gets something from your basic plan. And if you set up a method for doctors having medical school loans reduced in exchange for treating those patients, I bet you'd not have much trouble recruiting young docs.
Surely there are problems with this. So what am I not taking into account?

Another Modest Proposal
Forgive the divergence, but I'm still reeling from hours and hours of Deadliest Catch last weekend, and I have an idea.
The guys working these boats use, forgive me, salty language, and Discovery channel does a lot of bleeping. Fair enough, it is a family channel after all, even if it is on cable. But I am an adult not offended by hearing grown men saying they're "not catching shit." In other words, I'd like my reality programming to more accurately reflect reality.
For quite a while now, we've had a technology available called Second Audio Program (SAP), which allows a second audio track for a television program. You've probably seen "En Espanol on SAP" or something like that before. Why not have Discovery broadcast an uncensored version of the audio via SAP, and let me choose whether I want to hear the bleeps or not?

LKY Ranch BBQ and Spring Frolic
The 24th Annual LKY Ranch BBQ & Spring Frolic is now history. For the first time ever, the day was marked by rain. Between midnight last night and this morning, the rain gauge went up nearly five inches, with another inch still to come during the day. The turnout was lower than usual, but not the enthusiasm. As Linda explained to a person on the phone this morning, "Haven't you ever heard of a hurricane party?"
The good news is it quit raining for good about 1:30, and it was actually pretty pleasant on the porches.

Born a Moose
Every Friday, a man in Newfoundland fired up the barbie in the yard and cooked up a big moose steak. This was very annoying to his neighbours, who, being Catholic, were forbidden meat. They talked to the Priest, who, in turn, talked to the epicure. To the surprise of all, he agreed to become Catholic. On the day of his Confirmation, the Priest anointed him with the Holy Water, and said: "A Methodist you were born, a Methodist you were raised. You are now a Catholic."
THEN, they told him about meatless Fridays.
The next week, his neighbours were again assailed with the heavenly, but naughty aroma of charring moose meat. The Priest was immediately called, and went to the backslider's home. As he rounded the corner of the house, he beheld his new convert sprinkling barbie sauce on the steak.
Saying: "A moose you were born, a moose you were raised. You are now a codfish."

Groan
Dolly Parton and Queen Elizabeth went to the Pearly Gates on the same day. They both met with an Angel to find out if they would be admitted to Heaven.
The angel said “Unfortunately, there’s only one space in Heaven today so I must decide which of one of you will be admitted.”
The Angel asked Dolly if there was some particular reason why she should go to Heaven.
Dolly took off her top and said, “Look at these, they’re the most perfect breasts God ever created and I’m sure it will please God to be able to see them every day, for eternity.”
The Angel thanked Dolly, and asked Her Majesty, Queen Elizabeth the same question.
The Queen walked over to a toilet, pulled the lever and flushes it without saying a word.
The Angel immediately said, “OK, your Majesty, you may go into Heaven.”
Dolly was outraged and asked, “What was that all about?”
“I showed you two of God’s own perfect creations and you turned me down.”
“She simply flushed a commode and she got admitted to Heaven! Would you explain that to me?”
“Sorry, Dolly,” said the Angel, “but even in Heaven, a royal flush beats a pair — no matter how big they are.”

Comet Lulin (C/2007 N3)
From Wikipedia:
Comet Lulin (official designation C/2007 N3 (Lulin)) is a non-periodic comet. It was discovered by Ye Quanzhi and Lin Chi-Sheng from Lulin Observatory. It peaked in brightness and arrived at perigee for observers on Earth on February 24, 2009, at magnitude +5 and at 0.411 AU from Earth. … According to NASA, Comet Lulin's green color comes from a combination of gases that make up its local atmosphere, primarily cyanogen and diatomic carbon, which both appear as a green glow when illuminated by sunlight in the vacuum of space.
I was pleasantly surprised that PHD Guiding was able to guide on the comet. The streaks in this image are the background stars, smeared by the hour-long exposure on the comet itself as it sped through the solar system.

NGC 2264, The Cone Nebula
The Cone Nebula (also known as NGC 2264) is an H II region in the constellation of Monoceros. It was discovered by William Herschel in 1785. The nebula is located about 800 parsecs or 2,600 light-years away from Earth.
The Cone Nebula is part of the nebulosity surrounding the Christmas Tree Cluster. The designation of NGC 2264 in the New General Catalogue refers to both objects and not the nebula alone.
The diffuse Cone Nebula, so named because of its apparent shape, lies in the southern part of NGC 2264, the northern part being the magnitude-3.9 Christmas Tree Cluster. It is in the northern part of Monoceros, just north of the midpoint of a line from Procyon to Betelgeuse.
The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust in front of a faint emission nebula containing hydrogen ionized by S Monocerotis, the brightest star of NGC 2264. The faint nebula is approximately seven light-years long (with an apparent length of 10 arcminutes), and is 2,700 light-years away from Earth.
William Herschel discovered the Cone Nebula (which he designated H V.27) on December 26, 1785. It is part of a much larger star-forming complex—the Hubble Space Telescope was used to image forming stars in 1997.
I'm disappointed in this image after having M45 come out so well.

M45, The Pleiades
In astronomy, the Pleiades (Messier object 45) are an open star cluster in the constellation of Taurus. It is among the nearest star clusters. It is the cluster most obvious to the naked eye in the night sky. Pleiades has several meanings in different cultures and traditions.
The cluster is dominated by hot blue stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternate name Maia Nebula after the star Maia), but is now known to be an unrelated dust cloud in the interstellar medium that the stars are currently passing through. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.
