Chasing the moon

The March "super moon" got me started (crazed? loony?) photographing the moon again. This time I'm creating a test sequence, if you will, using the OM 300mm with the E-P2 and adapters. I bought the used OM 300mm to get a bigger image of the moon over the Zuiko Digital 50-200mm zoom. It was cheaper than buying either the EC-20 or a telescope and I can easily task the 300mm for other terrestrial uses.

Why do I keep doing this, especially when there's other resources like Nasa's Lunar Reconnaissance Orbiter (LRO)? Because there's something deeply satisfying in doing it yourself, even if it's no where near as detailed. There's something magical watching the terminator crawl across the surface of the moon, picking out craters in deep shadow. I'll never grow tired watching it happen, no matter how many times it repeats. That curvature, those shadows, show that the moon is a real body in space, something you can walk on. So close, and yet so far.

Even at 300mm, or 600mm effective focal length with the E-P2's sensor, the size of the moon's image compared to the size of the frame is small. To achieve what I would consider an effective image size, I'd want something to gives me four times the image size, or 1200mm (2400mm effective focal length). We're talking about a very expensive conventional optic here; for example the Canon EF1200mm 1:5.6 L sells used for $99,000. That is, if you can find one.

Maybe I really will get that telescope after all. My wife is going to kill me...

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

first night for the gingersnaps

The first night has passed and the two have managed to survive, in spite of what their tiny hearts might have thought when first arriving. Greebo, the larger of the two, has been in hiding the entire time so far. Ponder has spent the time zipping in and out of hiding spots, checking things out, and learning just how comfortable pillows are for resting your head.

During the night I felt the tiny body of Ponder hitting the bed as he leaped up on the side, and then climbed to the top to run around on top of me. At least once he play-attacked my fingers. He might be small but his claws are still quite sharp.

When I got up in the morning the bowl of cat kitten food was fairly well depleted. It's been refilled and fresh water put in the big dish on the floor. I'm assuming that both Greebo and Ponder are feeding and drinking. I have seen Greebo under the furniture peeking out at me when I went looking for him. I'm leaving him alone while he continues to adjust.

So far the guys h…

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…
