Good Nights For Sharing Stars


The past weekend, the weather gods were smiling on us. The Amateur Astronomers Association of Pittsburgh (AAAP) was able to hold four successful star parties, two at each of our observatories, Wagman and Mingo Creek. A few clouds drifted by, but the festivities went on, nevertheless.

    We had a thin sliver of a moon to look at on both nights. Since the moon was visible before the sun set, it was the first major attraction for the member's scopes. A couple members had solar filters and were able to show early visitors views of the sun's surface. At the present time the sun has lots of sunspots on it, making it an interesting view.

    The planet Venus was our next target. The planet Mercury was off to its right, a binocular view if you looked carefully. Since the planets were close to the horizon, we only had a short time to observe them before they dropped down into the trees.

    Mars was observed for a short while but we moved back to the moon since there was so much more to see on it.  As the sky darkened, we moved on to other objects such as Albereo in the constellation Cygnus and the double stars, Mizar and Alcor in the handle of the Big Dipper. A few Messier objects were shown and we watched a couple low passes of the International Space Station. A few guests were lucky enough to see some falling stars though we had nothing to do with that!

      We had a group of veterans visit along with families, students and daters. (I can only assume they were dating…) Everyone seemed happy to be there, some even coming over before they left to thank us for sharing the skies with them.




                                                                     

    My favorite moment was when a small girl took a look at the moon and told her Grampa, “WOW, look at all those craters!” I didn’t have to ask if she had seen it, we all knew it!

    At the Wagman Observatory, the crowds started thinning out after 11. A few waited long enough to see the ringed planet, Saturn, through the Manka reflector. In the Brashear room, we had to wait until the planet rose over the roofline before we could observe it.

    Let me tell you, as always, Saturn is worth the wait! The 11” refractor gave a nice, steady view of the planet along with 3 or 4 of it's moons. The rings are moving towards an “edge on” view, they aren’t as wide open as they were a few months ago but it is still spectacular!

    This is one of the fascinating things about astronomy, watching how the planets (and Moon) change. Saturn’s rings are moving towards a point where we won’t be able to see them.  Venus has phases that it goes through, just like our moon does. Both are currently thin crescents. Soon Jupiter will be visible again in the late evening skies along with it’s four brightest moons. It is always enjoyable to watch as the positions of these moons change over the course of an evening.

    Church was early the next morning, so after spending 15-20 minutes with Saturn, I closed up the Brashear room. A couple members were still out in the field, planning on spending the rest of the night. (I should say morning since it was after midnight.) I went home and crawled into bed for a couple hours before I had to get up again. I definitely had something to be thankful for in the morning. A couple more nights of good observing added onto all the other great things we have in life!

    Next star parties are in August…see ya there?

Getting the Image onto Paper


As so often the case in any hobby, it isn’t always as easy as it seems. On the surface, it’s a walk in the park, but as you fall deeper and deeper into “the hole”, the ease you once saw slowly slips away. With most hobbies, if not all of them, the further down the hole you go, the lighter your wallet becomes.

    A while ago I wrote a couple pieces on shooting and developing film. It is a trip back into the past, before our cameras became miniature computers or just another accessory on our phones.

    I find it fun to rely on myself to get a sharp negative that has been properly exposed. The more I do it, the better I feel I've become. This motivates me even more. There are film cameras which have automatic focusing and aperture and shutter functions that can help improve my shots. A few of them are in my back room but so far, I’ve managed to avoid using them. I’ve stuck with the manual cameras.

    After developing a roll of film, I had been scanning them onto my computer. By using Photoshop I was able to adjust the pictures, correcting the brightness or contrast along with cropping them to provide an image that was similar to the one I had envisioned when I depressed the shutter. It was simple and didn’t take much time and I could accomplish it while sitting at my desk next to the window, with my coffee close at hand.  I was pleased with the results and they were easily shared with others.

    While talking with one of my friends, she told me that her husband had an enlarger and if I wanted it I could have it. We got together and I was given 4 or 5 boxes of gear! Inside there were 3 different enlargers, timers, lenses, red lights, film reels, tanks and a whole bunch of other gear. WOW, where do I start?

    I didn’t have a place I could put an enlarger. It would need to be DARK, a darkroom, light will ruin photographic paper! Darkness is a prerequisite. Many years ago, I should say, decades ago, I had made a darkroom in the back of my garage using black plastic. Later I made one out of a coal cellar. 

    While running my options around in my head, I decided to put the enlargers together. There were three of them, a larger unit and two smaller duplicates. The bigger enlarger excited me more but I decided to tackle ones that I was more familiar with, I had used enlargers like these in the past. They were Omega C700’s, a fairly simple design.

    Using an on-line manual they were quickly assembled. I put a negative in the holder and turned off my lights and turned it on and an image showed up on the baseboard! I adjusted the focus and it looked good! The image was square and everything seemed in focus. 


     The bigger enlarger, a Beseler 45MXT came next. Thankfully there was a manual included with it. I have to say it was like putting a 3-d jig saw puzzle together. Included was an exploded view with all the parts listed, complete with the size and length of the bolts. This was important since a few were missing, and I needed to visit the local hardware store to get replacements.

    The light source is a cold light, bought after the enlarger was purchased. It worked but the diffuser lens was missing. It is a piece of glass about 7 ¼ inches in diameter. I found ONE on line, in Canada but I was too cheap to pay the same amount for shipping as I did for the lens. I started looking around to see if I could find another one or to “Mickey Mouse” something together. I finally found some plastic sheeting at a hobby store that would work, or at least I hoped.

    Now, the next problem, where do I set these up? They did look kinda cool sitting in my living room, but I couldn’t use them there. I have a nice spot in my basement, unfortunately it leaks when it rains. I don’t want any water falling on this equipment!

    I cleared off some of my workbench. It is far from ideal but for testing purposes, it would work fine. There are open floor joists above it with water pipes and drains going through them. Shelves sit behind it with jars of screws, bolts, nuts and nails in them. Dust and cobwebs are everywhere.

    A wall of dark plastic helped shield the little light leaks coming from the kitchen. I did a few tests to see if I could see any others. I went in and turned all the lights off and stood there, searching for any light. I found a few small leaks and they were quickly covered over.

    Next, I brought in one of the smaller enlargers and set it up, hung a safe light near-by and set up a table to hold my trays. It was time for the first attempt!

    I bought a pack of 8x10 glossy paper, 25 sheets for my first try. The developer and the other chemicals were all new. I mixed them, filled my trays, selected a negative and did a test strip. Then…the big moment, I put a piece of paper into the easel and hit the button. A minute later, an image was looking up at me in the developer tray. Next it went into the stop bath, then the fixer and then off to the stationary tub where I wash the prints. Turning the lights on, I was pleased. It could use a bit of dodging, but for my first picture in decades, I was happy!

   I started cutting the paper into smaller pieces. A single sheet of paper is too expensive to waste on making test prints. This is a wonderful example of what I was talking about earlier. None of the essentials are cheap; chemicals, the paper and of course, same with the film!

    A couple days of making prints with the small enlarger got me excited about what the bigger machine could do. I didn't have enough room so I turned my toolbox 90 degrees to free up a little more space.  I re-dusted and removed the new cobwebs and then Ann Marie helped me get it into the basement. It just fit through the door; it was NOT a one person move.

    Finally the day came, everything was hooked up, all my essential supplies were at hand. It was time to try it out. Everything seemed to be working fine. This enlarger can handle up to a 4x5 negative but I don’t have a lens capable of handling one that large. I can envision my hole getting deeper... I was happy to see that I can make prints with my medium format negatives.

    I jumped a bit deeper into the hole and ordered another box of paper. This one was a smaller size but a larger quantity. 100 sheets of pearl finish 5X7 paper, more money falling around me in the hole. Another thing I am spending more of, is time, but after seeing the prints developing in my trays, it is all worthwhile.

    There are a few things which need fixed in the near future but for the time being, I’m able to print pictures onto paper!

    Looking at my prints, once again I realize that to make a good picture, it takes more than just good equipment; you need good subject matter, a good negative and we can’t forget, a bit of skill. (I’ll always be working on that!) It is exciting when all of these prerequisites come together. Meanwhile, I’ll keep trying to do my best, trying to get everything aligned, doing it the old-fashioned way, using a good old shovel to dig my hole by hand!

Rainy Day

Sitting in a small coffee shop, I look out of the window and watch as the traffic goes by. Thinking as the cars speed by, it seemed as if I’ve been doing this a lot, staring out the window.  So much of the day has spent doing this as compared to going outside and breathing in the fresh air. The weather tends to enforce this, the driving rain just isn’t inviting.

    It is another typical grey Pittsburgh day. The promise of rain came true, it has arrived. “Dismal” could be used to describe the day. There are no bright colors, nothing shines. Even the hoods and sides of the cars appeared muted.

    It is hard to be optimistic on days such as this. The chores around the house had been finished, a prescription still needs to be picked up at the local pharmacy and after that, the days plans will be completed.

    A fresh urn of coffee is being brewed, that is something worth looking forward to! A donut sits in a brown paper bag on the table. Decisions, decisions, should I wait for the coffee or just dig in, that is the question. I chose to wait for the coffee and continue to stare out the window and think.

    Looking at the uninspiring parking lot, the rain increases to a downpour. Going out to the car will involve getting drenched. The view from the window is a perfect spot to wait it out. Especially since a fresh cup of coffee is now in my hand.

    I had the idea that I would go out in search for some photos. A grey day didn’t mean that there wasn’t anything worth taking a picture of. The opportunities are endless no matter what the weather might present.

    Halfway through my cup of coffee the rain tapers off a bit, enough that I can make the “run” to the car. Back on the road, people in a hurry speed past me, their tires splashing my windshield and obscuring my view. The rains intensified again as I slowly make my way towards my pharmacy and then my nice, dry house.

    Thinking about photography, I realized that the only way I’d get any pictures today would involve getting very wet in the process. Still…the shots are always there, constantly changing as the day progresses and the weather changes. They are there; I just have to SEE them, I just have to get a little wet.

    The rain tapers off a bit so I take a short drive to a favored spot. Wildlife occasionally show themselves here, perhaps something will today.

    The rain has slowed to a mist, so I get out and take a short walk. I take a few pictures but nothing excites me. The rain increases again and I return to the car with nothing of importance stored in the camera.

    Then, it’s back to the quiet solitude of my home. A fresh cup of home brewed coffee, a partially read book to read and then, maybe a few more minutes of staring out the window…thinking about the pictures I could’ve gotten.


Spending Time

During the hot days of the last week, I found myself indoors more than out.  This can be a good thing since I can put a little more effort i...
