My attempt to document 40 sunrises in Eastern Cincinnati. Spring 2011.

Sunrise 71: The Cincinnati Observatory (Pinhole Solargraph Camera, Clear Blue Skies, Flowers)

I realized that I haven’t had too many “bike shots” recently. This small patio is where I sat and enjoyed the sunrise. I met a jogger who said that I was the only person she’s ever seen enjoying the sunrise here at her favorite spot.

Pinhole Camera! Ironically (or, perhaps not) the pinhole camera technology dates back to the late 1830s. Only a few years later, the 11″ lens now located in the Mitchell Building (the smaller of the two building on the Observatory’s campus) will be constructed.

This morning I got up with plenty of time to spare. The sunrise was around 6:30am and I was at the Mt. Lookout United Dairy Farmers filling up my thermos ($.99 for the entire 26oz! And free on Mondays! UDF rules) by 6:20am. I read the weather forcast last night so I knew that this morning was supposed to be “clear” with only 10-20% cloud cover.

The forecast was right! After the foggy sunrises of the last week the beautiful clear sunrise was a welcome change. To honor this clear morning Tuesday I continued past Ault Park and ventured on over to the historic Cincinnati Observatory on Observatory Ave. I have never actually seen the sunrise at the Observatory because I normally only swing by on on the way back from Ault Park. With the sun moving all over the sky this summer I wasn’t even sure if the view of the sun would be appropriate. As it turns out the sun has moved far enough back to the right that there were no trees blocking Sol as he came up over the ridge line. I was impressed with just how perfect of a sunrise spot the Observatory actually is, but I can’t be too surprised considering that astrological alignment is basically their biggest concern!

The history alone of the Cincinnati Observatory is worth checking out. I have always found it interesting that the original lens in the large building was originally in Mt. Adams but it was moved to this site due to the pollution building up in the city. I never realized that they didn’t actually move the building from Mt. Adams, just the hardware. So while the lens itself dates back to the mid 1800s, this building dates back to the move to Mt. Lookout in 1873. You can find the cornerstone of the original Mt. Adams building to the back right of the new building, dating back to 1843. Now that I think about it, this may be the oldest building stone in Mt. Lookout. I’m sure this isn’t actually true, but as it stands currently it holds the Ault Park Sunrise record. This even pre-dates the 1850s construction of Crusade Castle & Vineyard.
The cornerstone, borrowed from Sunrise 41.

At the Cincinnati Observatory, the sun rose up from the break in the trees.

Not a cloud in the sky. A beautiful summer morning that you’d expect to see just after a storm.

This spot is out in front of the main Observatory Building (built in 1873). There is a circular brick patio with a handful of benches lining the outside it. It has all the great things that you’d expect to see at a true Cincinnati historic site. Murdock Fountains, late 1800s street lamps, Ohio Historical Markers, A memorial sundial, pre-1900s buildings, and a dedication by John Adams on the corner stone.

Looking East from the patio at the second building on the campus. This smaller “Mitchell” building has the original Merz und Mahler 11-inch telescope that dates back to 1843. The “main” building houses the 1904 16″ Alvan Clark & Sons telescope. Thanks wikipedia!

Looking towards the main building across the sundial memorial.

To the west of the main building I saw a funny contraption sitting on the lawn. Upon closer inspection (and with no physical contact whatsoever, of course!) I realized that it is a pinhold solargraph camera.

I imagine the purpose of this camera is to capture the sun’s path for the 31-day period between June 28 and July 28. They’re almost done! I’d like to see the results of this camera and I hope that they publish it. It’d be neat to see the same thing for a month of sunrises, too.

I wonder how they compensate for the possibility of the camera being blown over by the wind?

Outside the Observatory there are two big flower pots.

The red / white combination of flowers made for a great arrangement. Considering how my own flower pot experiment is failing miserably, I took mental notes and physical pictures.

Classy Arrangement. Maybe next time I try this at home I’ll use this as inspiration.

  1. Hello!

    I’m happy to see that you’ve discovered my pinhole solargraph camera! It is pretty much exactly what you determined it to be – a device for taking a picture that records the sun’s path across the sky over the period of a month or more.

    The camera you found should provide a wide-angle field of view, showing the sun’s path starting at the eastern horizon and continuing up the sky until about noontime… so it will indeed capture a month’s worth of sunrises! This particular pinhole solargraph camera is also unusual in two respects, however: It is an unusually short exposure, only 1 month (normal exposure time is 3 or 6 months, to capture the full range of the sun’s apparent seasonal movement); and it is mounted on a tilted “equatorial” axis, paralell to the axis of the Earth’s rotation (whereas most solargraph cameras are vertical). It should be interesting to see what the results will be!

    I also have a number of other, more traditional pinhole solargraph cameras scattered around the Observatory’s grounds. They lack the tilted axis and might be left out for up to 6 months. But good luck finding them! Of the 10 cameras I made, 4 were easily visible – and 3 of those were quickly vandalized and destroyed! You found the 4th. The remaining 6, well… they’re smaller, well hidden, and fairly inaccessible. You might spot 4 of those on your next visit… if you have a VERY good eye.

    I do not yet have any plans to publish the results on the internet. But, if you would like to send me your email address, I will be happy to send you a copy of the picture from the camera you discovered, after I open that camera later this week!

    Oh, and thank you for your thoughtful and well-written treatment of the Observatory and its history!

    • Leo, Thank you for stopping by! It is quite interesting that you found out about this article the day it was published. May I ask how you found it? It is unfortunate that your other cameras were vandalized, that’s a real shame. Was it that they were too hidden and maybe people didn’t know what they were? The 4th remaining pinhole camera is incredibly obvious, I am glad to see it hasn’t been vandalized.

      I am very interested in checking out the results of your pinhole solargraph camera! And now that you have alluded to the smaller hidden ones, I’ll make it a point to try and see if I can track any of them down.

      Thanks again for stopping by. I try to feature the Observatory a few times a month. I always find something new and interesting it seems like! Any idea what sits at the original location in Mt. Adams? I’m not even sure where the original location is. Blaine

      I would also love to see a picture of the 30 days that your pinhole camera captured! Have you considered posting it online? I just made a pinhole camera for my class and I didn’t have much luck with my images… 😦

    Hello, My name is Debbie and i have recently come across your web page while searching for information about pinhole cameras for a photography class i am taking. I am fascinated and impressed with your pinhole camera uses and techniques. I am interested in learning how to do a time lapse photo such as you have done and would like to know what you used for your photo paper. I have a couple of pinhole cameras that i recently made for my class and have been playing around with them for a negative and a positive paper. My times have only been 4 minutes and i am curious how you go about getting a picture without over exposing you picture. I would love to hear back from you so i can try such a project as you have mastered yourself. Please contact me via email. Thank you
