A Spring Awakening After A Long, Cold Winter
Being the president of two astronomy clubs, one would think all I do is spend my time gazing at the stars. Sure, I own 3 telescopes, a couple of pairs of binoculars, a number of astronomy books and know most of the "good" astronomy sites, but I still find it hard to get motivated to observe from the light polluted suburbs of Columbus, OH.
Tonight I hemmed and hawed about whether to take a scope out. I was playing on Facebook around 7:30 and zenith was clear, but clouds threatened all of my horizons. I did a quick check of the Clear Sky Clock and it claimed the weather would clear. Again, I paused, but then decided to take out my Orion XT8. I bought this scope about a year ago for a steal, but the computer controller has seemed to have issues. Now that I have the NAA Astro Club XT6 back in my garage, I was able to try it's computer controller and see if it was the IntelliScope or something else in the XT8.
I set-up at the end of the drive way and was being taunted by the clouds (they had moved overhead, but were whimsical and fluffy). I started to see Venus poking through the clouds to the west, so I thought, "What the heck?" and pointed the scope in that direction. I anticipated a full disk, but was pleasantly surprised by the ultra-thin crescent. Even through the lingering clouds and trees it looked amazing. Now, I should have known Venus was a crescent, but since I hadn't been doing much serious observing or study for a few months, it was a nice first light of 2009. I called my neighbor and his 5 year old son over to take a look (they had just gotten home from the store) and they oohed and ahhed over our sister planet. I pointed the scope at Sirius just so my neighbor's son could see what a bright star looked like in a telescope. It was starting to get dark and I knew I would lose their attention soon, so I turned to M42 (the Orion Nebula)and pointed out the trapezium. I was using a 26mm eyepiece so we were only getting about 45x magnification, but in this light bucket, the tiny trapezoid is easy to pick out in the large dust cloud. Lastly, I swing over to M45 (the Pleiades) and get asked, "What am I looking at?" "It's an open star cluster," I respond, forgetting how things like this excite astronomy geeks, but not the general public. I tell them I am going to see Saturn next, but they decide to head in as it's time for the son to go to bed.
I swing over to what I think is Saturn and sure enough, there she is. 800 Million miles separate us, but I can clearly make out the rings. I switch to a 7.5 mm eye piece which jumps my magnification to 160x. Even through some lingering haze and MASSIVE amounts of light pollution, Saturn appears about 1/15th as wide as the field of view and all orange/yellow. Her rings are almost perfectly perpendicular to our view, so there's no hope of seeing Cassini's Division, but I still enjoy the view. I don't remember when I last looked through the scope, but it was sometime last fall and I remember how much I enjoy looking at the stars.
Now, for the real reason I pulled the scope out. I've been toying with trying to sell the scope and even had some nibbles on it, but nothing solid yet. I plug in the club's Intelliscope controller and decide which two stars to use. With all of the light pollution (yes, this is a running theme because it is so overwhelming) I decide on Castor (in Gemini) and Rigel (in Orion). I turn the controller on, confirm the two stars and wait for the verdict. My error ratio is -0.1 (it needs to be within +- 0.5) to be effective. I decide to go back to Saturn, since I already know I can easily find it if the controller cannot. After zeroing out the locator arrows, I look in the eyepiece and VIOLA!...Saturn is slightly off center, but visible. I push in M42 and swing over to the Orion nebula and again, slightly off center, but there. I'm quickly coming to the conclusion that it is my IntelliScope controller that is the issue. This is not the conclusion I desired from this little test.
I unplug the clubs controller and go get my own. I plug it in, point the scope zenithward (that's straight up for you newbies) and turn the scope on. Again I use Castor and Rigel and wait for my results...........................................+29.9! "WTF???" is my first thought. "Maybe I used Pollux and not Castor," I think. So, I decide to try again. This time I use Sirius and Polaris, giving myself a wider portion of the sky from which to work. The result? -29.0. I am convinced that my controller is hosed and that I will have to see if Orion will fix it or just try to get another $150 out of me for a new controller. (NOTE: For the record, I was using an illuminated retical eyepiece to center the alignment stars, so I know I was dead center and that was not causing the error. Of course, this only added to my frustration over the situation.)
I decide to call it a night and within 10 minutes I have everything packed up and put away. Just one more reason I like this scope. Now if I could only get the controller to work, we'd be all set and it would be safe from the auction block.
Keep looking up!

PS: Astronomy for Youth begins our season on Saturday, March 21st at the Mohican Outdoor School Near Mansfield, OH. I hope to see you there!
The company for which I work has graciously purchased a telescope (an Orion XT6, with the optional Go-To controller) and all the accessories we need for astronomical observing. Since this was a club sponsored event, I brought the club scope and got it rigged up for the sun (note the silver solar filter over the top end of the telescope). I took a few glimpses of the sun, but was disappointed at the lack of sunspots, however, the lights and rigging on the football field created interesting patterns in the eyepiece as the sun set behind them. *****NOTE: DO NOT EVER LOOK AT THE SUN DIRECTLY! WE USE SOLAR FILTERS
Al arrived shortly after that bringing his new tripod and mount for his
As the sun set behind the trees, we did an "about face" and
The father thanked us for our time and continued to work on the scope. A short while later he informed us that it was working better. Curiously, we asked what he had done to fix it. "I just took off the counter weight and it works fine now," he shrugged. Sometimes it's the easiest solutions that produce the greatest results.
I explained the different types of telescopes that were set-up and how they gather and focus light. We then started talking about the full moon and how the moon moves through it's phases. I volunteered Ron to represent the sun, I was the moon on the children were the Earth. As I moved around in "Earth", I noticed Dan had joined Ron in the sun position and was illuminating me with a small flashlight, which of course added to the effect. Al had brought some hats that were donated last year by
The kids seemed to enjoy the presentation, but I sensed that their attention span for the lecture had been spent and they were itching to look through the scopes. I reminded them one last time to not grab any of the scopes and to ask for help if they wanted to look. Then I turned them loose.
