Well, [livejournal.com profile] duriyah's research resolved my question a couple weeks ago of what those bright lights in the sky were. But it didn't resolve the most puzzling aspect -- why was I seeing them as having such length?

I figured that one out this past weekend when we were sitting out under the full moon. I noticed Jupiter, and noticed that it had length. Then I moved my head to look directly at it.... and it was just a point. Moved my head back so it's in the corner of my vision, and it gets length again.

I finally realized that it was the optical lens distortion toward the edge of my glasses!

Having worn glasses since sixth grade, and being very nearsighted without them, I normally never even notice that distortion. I often forget that the glasses are there, and almost always forget that the correction introduces some distortion when I'm not looking straight ahead.

Anyone else watch the moon go down this evening? Wow, yet another time I wish I had a telephoto lens on my digital camera. (I've had to accept the fact that the lens on my digital is too wide-angle to get any good moon shots, ever, and I've gotten too spoiled by the instant gratification of digital to go back to my old all-manual film SLR.)

But I'm wondering about the identity of the bright thing in the sky near (left of) the moon tonight. I've been noticing it and a similar one in the south (but higher, maybe 30 degrees up) around dusk for weeks now. (Obviously the first one is not always next to the moon.) Their brightness makes them stand out, and I would assume that they're planets, probably Venus by the moon tonight.

Except for one thing: They sometimes appear to have length, rather than being little balls or points of light. Maybe 5-10 times longer than wide.

Planets don't have such proportions, unless the rings of Saturn have become a lot thicker lately. I wondered about satellites, but they either visibly move across the sky or don't set in the west with the rest of the sky. Similarly, these aren't airplanes.

I suppose comets could be a possibility, but I think I would've heard about comets this bright.

So I figure planets remain the most likely answer, combined with some weird atmospheric phenomenon that's blurring the light across a distance rather than just causing twinkling.

So has anyone else seen what I'm talking about?


(BTW, I realize that this could all be a localized phenomenon around Canton, but I did at least see the higher southern one Friday night on I-70 about 30-60 miles east of Columbus.)

Last Monday my latest new toy arrived, a small 5-megapixel digital camera, the result of redeeming an Amazon.com gift certificate.

After a bit of image editing, the best of the results so far.... )


Maybe one of these days I'll get a printer to go with it....


Update: A handy book for tips on various aspects of digital photography is Digital Photography Hacks by Derrick Story.
