When I put that last one up on Flickr I titled it "Acid Indigestion".
I'm guessing the guy probably doesn't have too bad a problem with light pollution. He is located in a quiet old part of town without too many street lights and he is sort of shielded on a couple of sides by some very nearby mini-mountains. We're quite a bit outside Tokyo.
Click here and the little red tag shows precisely where the home observatory is located. In fact, if you click on the "+" button enough times or move the slider all the way up, that little building itself is on the map and the red tag is squarely on it.
Pete, the answer to the museum reference mystery is easily revealed if you click on the photo and enlarge it. I composed the photo that way on purpose, just to see if people pay attention to detail.
That Tak 28/3.5 has sat around in my bag unused for most of the time I've had it. But I'm finding on walkabout photography I absolutely love the thing. I've been very pleased with the job it has done over the last several days.
EDIT: Found
a site giving a concise explanation of the Jizo statue.
The red caps and capes that are usually placed on them are meant as a sign of gratitude for Jizo's protection (or a palliative to ward off his wrath) and since this was New Years, a time that holds a significance on a level with Christmas (although of a different nature, of course) they were provided with new attire. Sort of like your depression-era relatives who regaled you with stories of getting a new pair of shoes but once a year and having to make them last.
