December 18, 2008 #067 - SN 1987a
Fast forward a few years. Late one night in February 1987 I was lounging on the bed and listening to shortwave broadcasts on my Kenwood R-1000 receiver with a long wire antenna. I was still tuning through the frequencies, listening here and there, writing what stations and type of traffic I picked up. Then to my surprise I hit upon traffic between South America and the United States. I was listening to the operators, speaking in English, transmitting information about a supernova just discovered in the southern skies. One of the brightest an nearest in modern times. They were talking about SN 1987a but it had no designation at that time.
This supernova was discovered on the 23rd day of February by a Canadian astronomer, Ian Shelton. He was working at Las Campanas Observatory in Chile when he made the discovery in the Large Magellanic Cloud. That would be about 160,000 light years away but it was visible to the naked eye. In the next few months and even today there is much excitement and research going on to discover the secrets of this explosion and what it can reveal to astronomers and stellar physicists.
The purpose of the message was to disseminate astronomical data between observatories and astronomers. This would facilitate more resources being brought to bear to study the fast breaking event. When I think back to that night It still amazes me that I caught that traffic. What are the odds of being on the shortwave at that specific time and hitting that one frequency out of a multitude of possible frequencies. The shortwave bounce had to be just right for my spot on the earth to pick up that transmission. It was kind of like hitting the lottery to hear this breaking news before the rest of the world heard it. Even though I have never seen this wonder in the night sky I will have this memory to treasure!

December 16, 2008 #066 - First Lunar Eclipse
Anyway, I remembered that a childhood friend "Bob" and I began a project in art class during early grade school that consumed many days of work. We decided to draw and color a 36" map of the moon. The teacher supplied us with a large white poster board to produce our masterpiece on. Remember, this is many years before the space age. We worked diligently drawing and coloring in craters, rills, seas, and mountains. What inspired this project is not clear anymore, maybe a lunar map in the back of an atlas of the earth or a magazine article photo in possibly Look, Life, or the Saturday Evening Post. We completed it over the coarse of many art class periods and it was quite impressive for a couple of young budding space science students. After completion it was hung in the class room by our teacher for the rest of the year. When summer vacation came we had a problem. How to divide one artwork by two boys. Being best friends we compromised and each kept it a month. Over the years it fell into disuse as boyhood things do, and one of our mothers probably decided to clean our rooms and the moon was lost.
This memory lead to another. A year or so later Bob and I decided to watch our first lunar eclipse. My parents had just purchased an old farm house, their dream home. No more rentals with Dad fixing the landlords properties for rent credit. It was a great place out in the country for astronomy. We rode the school bus home Friday evening and set up my Edmund 3" reflector for our observations late in the evening Saturday night. It was clear and cold with about an inch of snow. There was an old fuel platform out behind the smokehouse. This had once held a metal tank secured for gravity flow of fuel to the farm equipment. We decided that was our observatory. I can not explain why it was any better than on the ground!
Two boys went to bed that night but didn't sleep much. In anticipation we were up well in advance of the start of the event, bundled in heavy clothes. As the eclipse progressed we eagerly watched, one at the eyepiece and one eyeballing the moon and then switching places. Every once in awhile we would go inside to warm up. We survived the night on mutual excitement and eyes full of wonder at the moons changing aspect and seeing the earths shadow move through space. We were two tired boys when Bob's parents came to get him at the end of the weekend, but we had seen our eclipse!

December 14, 2008 #064 - Amazing Full Moon
As I left for work at 3:15 am the sky was hazy which dimmed it's overall brightness. A half hour later I was standing where I had an unobstructed view for miles in every direction. It was at an altitude of about 15 degrees past the zenith. A ring appearing to have a faint rainbow hue with a wall thickness the same as the moon's diameter circled it at 23 degrees. Contained within this ring were six stars near mag 3 or brighter. I stood and took in this beautiful view for a while. There are some rewards for going to work at this time of the morning!

December 13, 2008 #063 - Amateur Astronomy Handbook
My favorite project was the Wide Angle Telescope - Camera constructed with the lens from a K-22 Aerial Camera Lens Cone with a Tessor Optical System, f/6, 24" focal length. The cost of this lens was (Used $39.50) (New $59.50) at Edmund Scientific. It stated that this lens cost the U.S. Government $1200, and we talk about the cost of government hammers today. That would be about 10 times that amount in today's dollars. Of coarse that was way out of my reach even at the used price! But I did look at those pages over and over. They even had one of these Lens Cones at the local Army Surplus Store where I lingered many times looking at it from all directions.
Just looking at these pages again makes me want to see if that K-22 is still available on the net.

December 10, 2008 #060 - The Griffith Observer
Griffith Observatory is located above Los Angeles, CA. They began publishing this booklet in 1937 and it is still published today. They have a cumulative index that you can download and they will provide photo copies back to the first issue. They are available for $8.00 each. The annual subscription is $23.00. Information can be found at:
http://www.griffithobservatory.org/observer.html
They have extensive programs for the public, all detailed on their website. The Sidewalk Astronomers even set up telescopes each month for public viewing. Based on the pictures, I would guess that as with many older observatory sites light pollution is a very bad problem for them. They have photos of binoculars mounted to provide views of Los Angeles, which doesn't look that far away. As many of us can attest, light polution is a common problem across much of the Midwest, not just California.

It was produced as a radio program for the series named Mind Webs. It is now public domain and can be obtained just for the downloading as an mp3. The production and quality are first class. It is my favorite of the hundreds of old time radio programs available for free on the Internet. If you are like me you will get a thrill as you listen and watch the moon drift across your field of view!

December 8, 2008 #058 - 2001 A Space Odyssey
If you are like me you purchase CD's, play them over and over for a time, then put them away to be rediscovered again at a later date. As I was preparing the last two blog entries, I came across one that I had forgotten for a few years. Everyone has probably seen the movie "2001 A Space Odyssey" by Stanley Kubrick and Arthur C. Clarke. The sound track is one of the most memorable from my boyhood movie trips. I remember my father taking me to see it at the theater. I was one of those who came out with my eyes glazed and jaw dropping. The effect lasted for several days.
I am not sure how well known this information is, but I doubt many know that the actual music soundtrack was the second written for the movie. Composer Alex North wrote the original score, but it was never used. If you would like to hear it, the CD was released in 1993 by Varese Sarabande Records as "2001 The Legendary Original Score", performed by Jerry Goldsmith and The National Philharmonic Orchestra. The CD is #VSD-5400. It is still available on the net.

December 6, 2008 #056 - Symphonies of the Planets
One of my favorites is a 5 CD set of sounds recorded during the two Voyager flights to the limits of the solar system. From the box, "Share the journey of a 5 billion mile trek to the outer limits of the solar system. Hear the beautiful sounds of the solar planets. The complex interactions of the cosmic plasma of the universe, charged electromagnetic particles from the solar wind, planetary magnetosphere, rings and moons create vibration 'soundscapes' which are utterly alien and deeply familiar to the ear. Some sounds are hauntingly like human voices singing, giant Tibetan bowls, wind, waves, birds and dolphins". If you can find this set either new, used, or maybe in a library, it is a unique and wonderful way to find out what we human beings are missing, due to our limited senses.
The set is 'Symphonies of the Planets' and was produced in 1990 by LaserLight Digital and is #15 925. It is still available on the net.

December 4, 2008 #055 - Used Book Stores
I love to look for books which cover my hobbies, astronomy and telescopes, kayaking, outdoor activities, and tons of other subjects. I have been a voracious reader all of my life. If I could I would have rooms full of books. Fortunately my wife tries to keep the brakes on me. She has the same likes but does not collect like I do. She reads and moves on, I tend to read and keep. Giving up a good book is like pulling teeth for me.
Not too long ago I found a complete, almost unused, bound set of Burnham's Celestial Handbook, Vol 1 thru 3 in a small town used book store. Now I realize that I had a paperback set, and that they were published in 66 and revised in 78, and so are a little long in the tooth. But, who in their right mind could pass this up for $15. I even ask the proprietor twice if that wasn't the per book price. "No" he said "For the set", gasp! Now, all my wife needs to do is figure out how to get me to part with the other set!

I have, been following the Astronomical and Space News. What wonders we have seen in the last few weeks. A spectacular meteor fall over Canada, pictures of not one but several planets around other star systems, the polar lander holding on much longer than anyone thought it would, finally freezing in the cold dark martian night. Who would ever believe the rovers would still be sending back data from mars and one even hoping to complete a multi-year trek to a new and much larger crater.
I have also been spending time on the Cloudy Nights Astronomy Site. This web area is one of the best places to keep up with the amateur astronomy universe. It is worth your attention, it is moderated to prevent what has happened to sci.astronomy news groups. There is something there for every facet of your astronomical hobby.

October 29, 2008 #052 – Maksutov Modification
Everything fit and worked great. I can detect no vignetting. Stars are pinpoint sharp and the Mak provides a very dark background. I can hear someone say, “Mak's are for higher power!” Yes but, this combo gives excellent views of globular clusters and low power views of the moon and brighter planets. My 1.25” eyepieces still provide that power boost. I have a Clave 30mm and Clave Barlow along with a couple of University Optics Konig's that brings the best out in the small scope at higher magnification.
The bottom line is that it works on my 127 and adds enjoyment to the hobby. What more could we ask for!

October 11, 2008 #051 – Vacation Odyssey Episode 5
After we left our son's home we had a week of vacation left. We decided to cross the mountains and then head north into Wyoming. That evening by luck we found a wonderful remote desert campground in southern Wyoming. There were no lights or light pollution, no other campers, and the moon was not due to make an appearance till almost dawn. It was a sky watchers paradise.
As the sun went down I stood and watched the sky darken. The stars began to appear, with more and more over the next few hours until I reached down to, at about midnight, a magnitude somewhere between 7 and 8 with my old eyes. M31 was amazing, the Coal Sack was as dark as I can ever recall seeing it. I had a hard time taking my eyes off the Milky Way. I do not think that I have ever seen so much even in the 1950's from my boyhood sky in the Midwest.
I must confess I never got out my telescope. I would stand and observe, jumping from one section of the sky to the next, then back again. Occasionally I would look through binocs but not for long. It was an eyes only night for me. A couple of times I caught a few winks in the tent then knowing that new stars were rising in the east I was up and out under the night sky again. I'm sure my wife thought I had lost my mind. My last observing session was just as the eastern night sky was beginning to fade and the crescent moon rose over the cliffs in that direction.
Over the next few days we traveled through the Tetons, Yellow Stone, west over the Big Horn Mountains, through southern South Dakota, Minnesota, Wisconsin and then a last minute dash home through the most light polluted skies in the Midwest, Chicago. I know that when I retire I will be spending more desert nights under the stars. Maybe I might get to that telescope!

October 10, 2008 #050 - Mosquitos
As a consolation for very little observation time, Mercury Messenger has returned some spectacular views on it second flyby. If you haven't seen them by all means take a look. Imagine what we will see when it goes into orbit in 2011.
The other story I have been following was the photographic capture and atmospheric entrance of the 3 to 15 foot Asteroid 2008 TC3 over Africa a few days ago. That must have been a spectacular sight. Most meteors are only the size of a grain of sand. It is amazing that even non professionals are able to catch photos at such short notice. Hope they didn't have to contend with the mosquitos maybe they used one of those remote control observatories! Perhaps I should look into that when my wife wins the lottery.

Another goal was to visit S&S Optika in Denver. I remember when they were prominent advertisers in Sky & Telescope but they have not been present in recent times. My son and I drove through downtown and headed south toward their store location. It is not a big place but what wonders they have in their show room. They have rows of scopes and cabinets full of optical goodies. There were many excellent quality used scopes and the people working there were very helpful. If I were a wealthy man with a big truck I would have taken several with me. Kind of a kid in the candy store syndrome! They had some excellent deals. They also have evening observing sessions where the public is invited to try out the scopes. If you get a chance to stop in, by all means it is well worth it. I have scanned a copy of their flyer for the blog.
I received another astronomical treat from my son, which he brought back from a recent business trip to Australia. I mentioned that I would love to see a copy of the Australian Sky & Telescope which he picked up for me. It is an interesting read, the local stories and the southern sky articles were great although a portion was articles that were published in the North American issue. Of coarse it was great to browse through the advertisements.

The night sky is great but other wonders pulled our eyes to the west. The Rockies are a wonder and to top it off snow fell in the high country. We took several trips to Rocky Mountain National Park, culminating in a drive to the alpine level above two miles.
One evening as we returned from the mountains their was a spectacular meteor fall just at dusk. We were traveling south about 40 miles north of Denver. A slow, brilliant green meteor trail began forming about 35 degrees above the city and appeared from our perspective to travel almost vertically down to burn out at about 5 degrees above the south horizon. I can only imagine what a show this would have been in dark skies away from the the city lights and an almost full moon.
On the subject of the moon, we were treated to amazing moon rises for almost a week. Coming off the mountains with the city lights stretching to the northern, eastern, and southern horizon the moon would rise, perfectly clear over the earths edge and looking larger than life. No haze was visible, and the lunar features were clear and distinct as it climbed above the earths limb. I have only observed this in the north country where the pristine orb rises out of Lake Superior, never over a fully illuminated city.

I have a Fuji E900 camera which takes great digital pics but the lens is not suited to photographing the night sky. I have always used a Cannon F1, 35 mm. This was a top of the line film camera in it's day but is now decidedly long in the tooth. My son had just purchased a new Nikon D40, just before we got there. I can never resist a new gadget. We began to experiment with it in the evening and after a while we were able to capture some serviceable lunar pics using the manual settings and a 300 mm lens.
It is amazing how sensitive these cameras are in low light conditions. Colors are captured even though the eye sees only shades of gray. The lights of Denver prevented any long exposures but here are four of our early tests. The fifth is a fast hand held snap of the moon with the E900 through the eyepiece of my 127mm maksutov.

We have a Jeep TJ and behind it an old military trailer in which we packed all the Stuff. You can bet my telescope found it's way in! I was itching to see some western skies. We headed out US 136. Traveling has always been a treat for us. We like to see small towns on the back roads and take our time. Interstate roads are for trips home as we always stay gone to the last minute. We crossed the Mississippi River at Keokuk and headed west across Missouri and Nebraska.
We really got into this tent camping. It took a couple of nights to work out the system, I having camped but my wife is new to a tent. By the second night we had it down pat and began enjoying the new life style. When we hit Nebraska the skies were getting much darker and trees were becoming few and far between.

I have a 70's vintage Meade catalog which I have scanned for the blog and will post over the weekend. It shows what they had for sale so you can compare it to the current offering.
By the way, doesn't the guy on page 8 look like Mr. Wizard? I can hear a chorus of who?
