Titan Descent Movie

Posted By David Eccles

I don't know if anyone has already posted this, but I thought it was cool. If someone already has, then my apologies. It's a time-lapse movie of the images taken by the Huygens Probe during its descent to Titan. You'll need Quicktime to watch. In the attached link, click on the smaller of the two images.

Enjoy

First Outreach Attempt / Seeking Object Advice

Posted By David Eccles

Hi All,

On Thursday, May 25th, I will be conducting my first outreach program with a group of 8th grade students, their science teacher, and parents. The viewing session will run from 8:30 to 10:30. At this point, I have confirmed 16 students (25-30 people if you count parents) and am looking for advice on an object list. Here's what I have chosen so far. Depending on your input, this list is subject to change. As always, your input is appreciated.

SATURN, MARS, JUPITER,
CLUSTERS - M3, M4, M13, M35, M37, M44, M92
GALAXIES - M51, M81
NEBULAE - M27, M57
OTHER - MIZAR DOUBLE STAR

I was also planning to spend a little time explaining how to measure RA and DEC by hand to assist in finding objects just by looking up.

If anyone could also give me a list of binocular objects, and web resources for beginners, that would help. All of this, as well as other information regarding distances (e.g., distance from sun to pluto / nearest star) will be part of a handout I'm printing for everyone to take home.

Am I missing anything? Let me know. Thanks

Clear Skies,

New Guide to Digital SLR Photography Released

Posted By David Eccles

I recieved an email over the weekend regarding a new CD / Book release titled "A Guide to Astrophotography with Digital SLR Cameras", by Jerry Lodriguss

Jerry is one of the premier astrophotographers with over 25 years experience and is well known amoung the astrophotographers world.

I purchased his previous guide to using Photoshop for producing 35mm images and found it be easy to follow and filled with useful information. I would highly reccommend checking out hi new release if you want to be serious about digital slr imaging. For a preview, follow this link.

DELTA IV ROCKET LAUNCH

Posted By David Eccles

Lompoc, CA -

Last night at approx. 8:30pm, launch crews at Vandenburg AFB completed the first successful launch of the new Delta IV rocket. This rocket was deploying a satellite (for whom, I don't know) and from the information I've gathered, it was a complete success. We had crystal clear skies and no wind for the event.

Because it was launched at twilight, there were some great effects created by the exaust trail. At first, the smoke was dark gray, but as soon as it reached above the horizon of the setting sun, the trail was displaying incredible hues of yellow, orange and red, as you would see in clouds during sunset.

About a minute later, we saw the booster seperation and could watch them burning out as they began to tumble away. My oldest daughter (14 and a dolphin lover) asked me if the boosters would crash into the ocean. I told her yes. Then she asked if anyone would retrieve them. Sadly, I had to tell her that no one would go get them. So chalk up another case of military littering of our planet (1 of thousands).

The last part of the event was the rocket punching a hole through the upper atmosphere, which creates a halo of blues and greens. The halo appears and spreads very quickly at first, then lingers for quite a while. At this point the rocket disappeared and that was it.

The satellite deployment was successful.

One interesting note. There are a number of launch pads (called slicks) on Vandenburg. The slick used for this is number 6. Apparently this pad was literally built over a native american burial ground (the Chumash tribe) and until last night, no launch from this slick has gone without some kind of problem. Rockets have failed to launch, explosions, misfires, etc.

There were several opportunites for some good photos, but I didn't have my camera with me.

Did anyone else see it? Lets here your impressions.

Clear Skies,
David Eccles

Bush's War on Heaven

Posted By David Eccles

Bush's War on Heaven

Space Cowboy

By BRUCE K. GAGNON

The White House has just released the new U.S. National Space Policy from the Bush administration. The new document makes several policy departures from past space doctrines. They include:

* Calling for the deployment of offensive weapons systems in space to "deter" and "deny" others the "use of space." This is a very provocative notion and will give the Pentagon the green light to put anti-satellite (ASAT) weapons in space that would be able to destroy other countries satellites.

* Saying the U.S. will "oppose the development of new legal regimes or other restrictions that seek to prohibit or limit U.S. access to or use of space." This means that the U.S. is now on record as being totally opposed to the development of an international treaty at the United Nations that would ban all weapons in space. The treaty, annually promoted by Russia, China and Canada, seeks to close the door to the barn before the horse gets out. The U.S. and Israel have been blocking such a treaty since during the Clinton years.

* The Bush administration military doctrine today calls for "preemptive" attack and "unilateral actions" around the world to protect corporate interests like oil and other diminishing resources. Thus we saw the 2003 "shock and awe" invasion of Iraq and now hear talk that a similar attack on Iran might be pending. The administration now says that it will no longer be bound by international treaties which would "inhibit" Bush's ability to strike at any time and any place on the Earth. Space technology, says the military, becomes crucial to U.S. ability to create "full spectrum dominance."

One of the first things the Bush administration did once in office was to withdraw from the 1972 Anti-Ballistic Missile (ABM) Treaty with Russia that limited the development and deployment of weapons in space. It is thus no surprise that George W. Bush now comes forward with this new national space doctrine that tells the Pentagon to move ahead with Star Wars.

A key reason for America's desire to kill the U.N.'s space weapons ban treaty negotiations is that the military-industrial complex views space as a new market. The weapons corporations have been saying for decades that Star Wars will be the largest industrial project in the history of the planet Earth. Both Democrats and Republicans get the message and understand that their corporate sponsors want them to leave the door open to a new costly and destabilizing arms race in space.

One other key element of the new Bush space policy is the expanded use of nuclear power systems to "enable or significantly enhance space exploration or operational capabilities." What this means is that the aerospace industry wants to establish mining colonies on the Moon, Mars and other planetary bodies and they want to power these bases with nuclear reactors. The military has also long been saying they need nuclear reactors in space to provide power for space weapons systems. So the nuclear industry also plans to utilize space as a new market for increasing corporate profits.

Just weeks ago, from Oct. 1-8, peace groups around the world took part in our annual Keep Space for Peace Week of local actions. Protests, teach-ins, video showings and other activities were organized in order to help expand the consciousness of the people of the world about the need to move now to protect space from a new arms race. Not only will putting weapons in space be expensive, but it will also be incredibly destabilizing for the world. Already we see the tragic growth in the nuclear arms race on Earth. Will arming the heavens with weapons make us safer? Absolutely not.

The time has come for the American people to call on Congress to cut funding for the research and development of Star Wars technology. Let's use our hard-earned tax dollars to fund health care, education and environmental clean-up here on our home planet. Let's work now to prevent another maddening arms race from happening before it is too late.

There's other problems not mentioned. For one, it is imposssible for NASA to guarantee these systems wouldn't pose an environmental threat to either our atmosphere or the planet surface in the event one of these systems falls out of orbit and burns up during re-entry. Anyone in the government or NASA who says otherwise is lying.

The only reasonable and logical position NASA can take regarding developement and deployment of these weapon systems is to flat-out refuse to participate in any way whatsoever. The same position should be taken by the ESA, Japan, China and Russia.

Newbie looking for input

Posted By David Eccles

Can't give you any info on the scopes, but if your looking for a place to move with dark skies, I would suggest New Mexico. Look up site called "Windmill Ranch". About 2 hr drive northwest of Albequerque. Not developed, but water and electric pulled to property line.

20 acres for $18,000. Only catch is you have to live at 6100ft elevation.

I'd do it myself, but I have a disabled child and New Mexico's state medical services is one of the worst in the nation.

Telescope Appears to have Died?!

Posted By David Eccles

Sell the scope and buy a Celestron. j/k grin

Iwas going to suggest a new power supply, but that's not the issue anymore. Have you talked with tech support? Is it still under warranty?

Radial Guider manual question

Posted By David Eccles

I read and printed the doc mentioned in this forum and noticed it speaking of a "Drive Corrector". Can any of you explain what a drive corrector is, and is it really neccessary for astrophotography?

Film hypering

Posted By David Eccles

Film hypering is an expensive and tedious process. Some of the advangtages you get from it include greater light sensitivity and shorter exposure times, but the are much less expensives that yeild equal results. Additionally, each time you hyper a roll, it takes about 2 to 3 days for a roll to be ready.

Using films such as Fuji Provia 200 or 400 will give you near equal results as would hypered films, and will be far less expensive and time consuming. If you go to filmclub.com, you can order the Fuji Provia for about $3 to $5 a roll, verses hypered film kits costing upwards of $500 plus film and supplies.

On other disadvantage of using hypered films is you have to keep it frozen and the shelf life of a roll is about 30 to 60 days.

Hope this helps.
