When we moved to Eastern Washington, the thought was to put an observatory in the yard of wherever our home turned out to be. However, I found there was nearly as much light pollution in our new location as there was at our previous home over on the Seattle side of the Cascades. So, what to do?
I started in 2013 looking for a spot to build a little observatory and maybe a cabin if the place was far from home. I found some pretty good spots but as I’d close in on making a decision, I found lots of little issues that would turn me off. I’ll list a few:
- Distance from home: After looking at lots of properties, I decided to limit my search to those within a 1 hour drive to fit my lifestyle.
- Elevation: I found there are inversion layers that often cover this area, and the layers are often quite low. As such there are times when the night is clear if you can get above the layers of fog/cloud. A few thousand feet seems to be enough.
- Access: Several properties looked great, but getting to/from them was difficult and/or hazardous. Difficult I can deal with. A thousand foot drop off a snow covered narrow dirt road….Nope!
- Snakes: Some properties I found were in areas with LOTs of rattlers. Not what I want to deal with.
- Area Growth: Is the area going to change soon? More houses, power lines, higher taxes, etc.
Just a few of the things you’ll be thinking about if you decide to build an observatory. I can almost guarantee your decision will end up like like mine….. a raging bundle of competing compromises.
So, Where did I end up: I found a property 35 minutes from home, up on a bluff East of the Columbia river. Undeveloped land at 4200 ft, with nothing but sagebrush. No power, no water… no utilities at all. About 1.5 miles of rough, barely maintained dirt road off the highway. Because the road isn’t plowed, getting back to the property in the winter is very difficult (the snow’s been light this year so I might be able to make it…. may I’ll try at the new moon).
Here’s a couple pictures of the land and the night sky from there:
So that’s that! Now to start working on building the observatory.
